philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 5 associated link controller. the received data is also transmitted out the other active cable ports. the cable status, bus initialization and arbitration states are monitored through the cable interface using differential comparators. the outputs of these comparators are used by internal logic to determine cable and arbitration status. the tpa channel monitors the incoming cable common-mode voltage value during arbitration to determine the speed of the next packet transmission. the tpb channel monitors the incoming cable common-mode voltage for the presence of the remotely supplied twisted-pair bias voltage, indicating the cable connection status. the pdi1394p11a provides a nominal 1.85 v for driver load termination. this bias voltage, when seen through a cable by a remote receiver, is used to sense the presence of an active connection. the value of this bias voltage has been chosen to allow inter-operability between transceiver chips operating from either 5 v nominal supplies, or 3.3 v nominal supplies. this bias voltage source should be stabilized by using an external filter capacitor. when not powered, the pdi1394p11a prevents the bias voltage from erroneously powering up the part as is seen in some other phys. 8.0 recommended operating conditions symbol parameter condition limits unit symbol parameter condition min typ max unit v dd dc supply voltage source/non-source power node 2.7 3.3 3.6 v v ih high level input voltage cmos inputs 2.0 5.5 v v il low level input voltage cmos inputs 0.8 v v id100 differential input voltage cable inputs, 100mbit operation 142 260 mv v id200 differential input voltage cable inputs, 200mbit operation 132 260 mv v idarb differential input voltage cable inputs, during arbitration 171 262 mv v c common mode voltage tpb cable inputs, 100mbit or speed signaling off, source power node 1.165 2.515 v v ic100 common mode v oltage tpb cable inputs, 100mbit or speed signaling off, nonsource power node 1.165 2.015 v v cs common mode voltage tpb cable inputs, 200mbit or speed signaling, source power node 0.935 2.515 v v ic200sp common mode v oltage tpb cable inputs, 200mbit or speed signaling, nonsource power node 0.935 2.015 v receive in p ut jitter tpa, tpb cable inputs, 100mbit operation 1.08 ns recei v e inp u t jitter tpa, tpb cable inputs, 200mbit operation 0.5 ns receive in p ut skew between tpa and tpb cable inputs, 100mbit operation 0.8 ns recei v e inp u t ske w between tpa and tpb cable inputs, 200mbit operation 0.55 ns i o /i o out p ut current i o /i o sysclk 16 16 ma i ol /i oh o u tp u t c u rrent , i ol /i oh control, data, cna, c/lkon 12 12 ma i o output current tpbias outputs 3 1.3 ma f xtal crystal frequency parallel resonant fundamental mode crystal 24.5735 24.576 24.5785 mhz t amb operating ambient temperature range in free air 0 +70 c

philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 11 17.1 arbitrated (short) bus reset a 1394-1995 software initiated bus reset assumes that the state of the bus is unknown when reset occurs and requires that the reset be long enough to permit the longest transaction to finish and still complete reset (167 m s min. to 250 m s max.). the total duration of bus initialization is longer than the nominal isochronous cycle time (125 m s) and may disrupt two isochronous periods. this compels device designers to add additional buffer depth to preserve the smooth flow of isochronous data from the perspective of their application. if a node that initiates a reset arbitrates for control of the bus prior to asserting reset, arbitration time can be shortened significantly (1.3 m s min. to 80 m s max.). this 1394a concept is known as arbitrated (short) bus reset, and is incorporated in the pdi1394p11a. the testm2 (pin 21) pins is used to enable arbitrated (short) bus reset mode. in 1394-1995 mode, this pin is tied high. in this mode, an arbitrated bus reset cannot be initiated from this node and will be treated as a alongo bus reset if initiated by another node. in accordance with the 1394-1995 spec, all bus resets on the entire bus will be alongo. to enable arbitrated (short) bus reset mode, set testm2 low. with the part in this mode, writing a 1 to the isbr (initiate short bus reset) bit (bit 7) of phy register 9 initiates an arbitrated bus reset. this mode also allows the phy to recognize arbitrated bus resets initiated by other nodes. non-arbitrated bus resets can still be initiated from this node and are recognized and processed correctly when initiated by another node. 17.2 setting the cps trip point the cable power status (cps) pin (pin 23) is used to monitor the cable power. when cable power voltage has dropped too low for reliable operation, internal circuitry trips, which clears the cps bits in the phy registers (bit 7 of register 0, and bit 2 of register 6). this action causes a cable power status interrupt which sets the cpsint bit in the phy registers (bit 1 of register 6). this bit can be cleared by a hardware reset or by writing a 0 to the cpsint bit. however, if the cps input is still low, another cable-power status interrupt immediately occurs. the cable voltage at which these events occur is adjustable on the pdi1394p11a. the external resistor (r) needed to set the cps trip voltage (v cable ) to a desired voltage can be calculated using the following equation: r (v cable 1.85v) 10 a the external and internal circuitry associated with the cps pin is illustrated in figure 5. comparator v comp 1.85v v cable r phy cps i comp 10 m a sv00921 figure 5. some typical threshold voltage values and their associated resistor values are shown in table 1. table 1. typical threshold voltage values v cab l e (v) r (k w ) v cable detector tolerance % with: cable () ( ) r of 5% r of 2% 5 315 6.8 4.4 6 415 7.3 4.8 7 515 7.8 5.2 8 615 8.3 5.6 9 715 8.8 6.0

philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 13 18.0 external components and connections 18.1 logic reset input (reset, pin 1) forcing this pin low causes a bus reset condition on the active cable ports, and resets the internal logic to the reset start state. sysclk remains active. for power up (and after power down is asserted) a 2 ms delay is required to assure proper pll operation. an internal pull-up resistor is connected to v dd , so only an external delay capacitor is required. this input is a standard logic buffer and may also be driven by an open drain logic output buffer. the reset pin also has a n-channel pull-down transistor activated by the power down pin. for a reset during normal operation, a 10 s low pulse on this pin will accomplish a full phy reset. this pulse as well as the 2 ms power up pulse could be microprocessor controlled in which case the external delay capacitor would not be needed. for more details on using single capacitor isolation with this pin please refer to the philips isolation application note an2452. 18.2 link power status input (lps, pin 2) in a non-isolated implementation a 10k w resistor is connected to the v dd supplying the link layer controller to monitor the link's power status. in an isolated implementation a square wave with a minimum frequency of 500 khz can be applied to the lps pin to indicate the pin is powered. if the link is not powered on, the control i/o's (pins 11,12), data i/o's (pins 13 16) and sysclk output (pin 9) are disabled, and the pdi1394p11a will perform only the basic repeater functions required for network initialization and operation. this pin is equipped with bus hold circuitry. 18.3 link request input (lreq, pin 3) lreq is a signal from the link layer controller used to request the pdi1394p11a to perform some service. this pin is equipped with bus hold circuitry and supports an optional isolation barrier. 18.4 power down input (pd, pin 7) this input powers down all device functions with the exception of the cna circuit to conserve power in portable or battery powered applications. it must be held high for at least 3.5ms to assure a successful reset after power down. this pin is equipped with bus hold circuitry and supports an optional isolation barrier. 18.5 system clock output (sysclk, pin 9) provides a 49.152 mhz clock signal, synchronized with the data transfers, to the link layer controller. this pin supports an optional isolation barrier. 18.6 control i/os (ctl[0:1], pins[11,12]) these are bi-directional signals used in the communication between the pdi1394p11a and the link layer controller that control passage of information between the two devices. these pins are equipped with bus hold circuitry and support an optional isolation barrier. 18.7 data i/os (d[0:3], pins [13,14,15,16]) these are bi-directional information signals used in the communication between the pdi1394p11a and the link layer controller. these pins are equipped with bus hold circuitry and support an optional isolation barrier. 18.8 test mode control and isbr mode inputs (testm[1:2], pins[22,21]) these two logic signals are used in manufacturing to enable production line testing of the pdi1394p11a. for normal use these should be tied to v dd . to enable isbr (arbitrated (short) bus reset) mode, set testm1 high and testm2 low. see section 17.1 for more information on isbr mode. 18.9 cable power status input (cps, pin 23) this is normally connected to the cable power through an external resistor. the circuit drives an internal comparator which is used to detect the presence of cable power. this information is maintained in an internal register and is available to the link layer controller through a register read. see section 17.2 for information on setting the cps trip point. 18.10 bus or isochronous resource manager capable input or link-on output (c/lkon, pin 27) on hardware reset, this pin is used to set the default value of the contender status indicated during self-id. the bit value programming is done by tying the pin through a 10 k resistor to v dd (high, bus manager capable) or to gnd (low, not bus manager capable). using either a pull-up or pull-down resistor allows the link-on output to override the input value when necessary. after hardware reset, this pin is used as an output to signal the reception of a link-on packet. a 6.114 mhz signal is supplied until the lps input is active at which point the c/lkon output goes low. 18.11 power class bits 0 through 2 inputs (pc[0:2], pins [30,29,28]) used as inputs to set the bit values of the three power class bits in the self-id packet (bits 21, 22 and 23). these bits can be programmed by tying the pins high to v dd or low to gnd. 18.12 cable not active output (cna, pin 31) this pin outputs the cable connection status. if all ports are disconnected this pin outputs a high. if any port has a cable connected then this pin outputs a low. 18.13 twisted pair i/o's (tpa[1:3]+, pins [45, 40, 36], tpa[1:3], pins [44,39,35], tpb[1:3]+, pins [43,38,34], tpb[1:3], pins [42, 37, 33]) these pins send and receive differential data over the twisted pair cables. two series connected external 56 w cable termination resistors are required at each twisted pair. each unused tpb pin must be tied through a 5k w resistor to ground. the tpa pins can be left floating. 18.14 twisted pair bias outputs (tpbias[1:3], pins [46, 47, 48]) these outputs provide the 1.86 v nominal bias voltage needed for proper operation of the twisted pair cable drivers, and for signaling to the remote nodes that there is a valid cable connection. three tpbias outputs are provided for separate connection to each of the three tpa twisted pairs to provide electrical isolation. a 1 m f capacitor to ground must be connected to each tpbias pin whether it is used or not. 18.15 pll filter (filter, pin 54) this pin is connected to an external filter capacitor used in a lag-lead filter for a pll frequency multiplier running off of the crystal oscillator. 18.16 oscillator crystal (xl, pin 56 & xo, pin 57) these pins connect to a 24.576 mhz parallel resonant fundamental mode crystal. the optimum values for the external shunt capacitors are dependent on the specifications of the crystal used, the suggested values of 12 pf are appropriate for one specified for 15 pf loads.
philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 14 18.17 current setting resistor (r[0:1], pins [59,60]) an internal reference voltage is applied across the resistor connected between these two pins to set the internal operating and the cable driver output currents. a low tcr (<150ppm/ c temperature coefficient) with a value of 6.34 k w 1% should be used to meet the 1394 standard output voltage limits. 18.18 isolation barrier disable (iso, pin 62) when iso is high, busholder circuits are enabled on the lreq, pd, and lps input pins and on the ctl, and data bidirectional pins. this mode also allows isolation using a single 1nf capacitor per signal line. details for this kind of isolation can be found in the philips isolation application note an2452. when iso is low, busholder circuits are disabled and isolation can be realized by using the scheme explained in annex j of the 13941995 spec. 18.19 supply filters (avdd, pins [24, 25, 51, 55], dvdd, pins [5,6,19,20], and pllvdd, pin 58) a combination of decoupling capacitors is suggested for each supply group, such as paralleled 10 m f and 0.1 m f. the high frequency 0.1 m f capacitors should be mounted as close as possible to the pdi1394p11a device supply leads. these supply lines are separated on the ic to provide noise isolation. they should be tied together at a low impedance point on the circuit board. individual filter networks are desirable. details of a phy-link interface supporting an optional isolation barrier are provided in annex j of the 1394 standard. 19.0 principles of operation the pdi1394p11a is designed to operate with a link layer controller. these devices use an interface such as described in annex j of the 1394 standard. the following describes the operation of the phy-link interface. 19.1 data transfer and clock rates the pdi1394p11a supports 100/200 mbit/s data transfer, and has four bi-directional data lines d[0:3] crossing the interface. in 100 mbit/s operation only d[0:1] pins are used, in 200 mbit/s operations all d[0:3] pins are used for data transfer. the unused d[n] pins are driven low. in addition there are two bi-directional control lines ctl[0:1], the 50 mhz sysclk line from the phy to the link, and the link request line lreq from the link to the phy. the pdi1394p11a has control of all the bi-directional pins. the link is allowed to drive these pins only after it has been given permission by the phy. the dedicated lreq request pin is used by the link for any activity which it wishes to initiate. when the phy has control of the bus the ctl[0:1] lines are encoded as follows: ctl [0:1] name description of activity 00 idle no activity is occurring (this is the default mode). 01 status status information is being sent from the phy to the link. 10 receive an incoming packet is being sent from the phy to the link. 11 grant the link has been given control of the bus to send an outgoing packet. when the link has control of the bus (phy permission) the ctl[0:1] lines are encoded as follows: ctl [0:1] name description of activity 00 idle the link releases the bus (transmission has been completed). 01 hold the link is holding the bus while data is being prepared for transmission or sending another packet without arbitrating. 10 transmit an outgoing packet is being sent from the link to the phy. 11 na none 19.2 request when the link layer controller wishes to request the bus, or access a register that is located in the pdi1394p11a, a serial stream of information is sent across the lreq line. the length of the stream will vary depending on whether the transfer is a bus request, a read command, or a write command. regardless of the type of transfer, a start bit of 1 is required at the beginning of the stream, and a stop bit of 0 is required at the end of the stream. bit 0 is the most significant, and is transmitted first. the lreq line will be required to idle low (logic level 0). 19.2.1 link layer controller bus request for a bus request, the length of the lreq data stream is 7 bits as follows: bit(s) name description 0 start bit indicates the beginning of the transfer (always 1) 13 request type indicates the type of bus request (see the table below for the encoding of this field) 45 request speed this should be 00 for pdi1394p11a's 100 mbit/s speed and 01 for 200 mbit/s speed. 6 stop bit indicates the end of the transfer (always 0) 19.2.2 link layer controller requests read register access for a read register request, the length of the lreq data stream is 9 bits as follows: bit(s) name description 0 start bit indicates the beginning of the transfer (always 1) 13 request type always a 100 indicating that this is a read register request 47 address the address of the phy register to be read 8 stop bit indicates the end of the transfer (always 0) 19.2.3 link layer controller requests write register access for a write register request, the length of the lreq data stream is 17 bits. the details of bits are as shown below: bit(s) name description 0 start bit indicates the beginning of the transfer (always 1) 13 request type always a 101 indicating that this is a write register request 47 address the address of the phy register to be written to 815 data the data that is to be written to the specified register address 16 stop bit indicates the end of the transfer (always 0)
philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 15 19.2.4 other requests and lreq the three bit request type field has the following possible values: bit(s) name description 000 immreq immediate request: upon detection of an idle, take control of the bus immediately (no arbitration) 001 isoreq isochronous request: arbitrate for the bus, no gaps 010 prireq priority request: arbitrate after a subaction gap, ignore fair protocol 011 fairreq fair request: arbitrate after a subaction gap, follow fair protocol 100 rdreg return the specified register contents through a status transfer 101 wrreg write to the specified register 110, 111 reserved reserved 19.3 operation of lreq sv00232 lr0 lr1 lr2 lr3 lr(n2) lr(n1) figure 8. lreq input sequence (each cell represents one sysclk sample time) for fair or priority access, the link requests control of the bus at least one clock after the phy-link interface becomes idle. if the link senses that the ctl pins are in a receive state (ctl[0:1] = 10), then it will know that its request has been lost. this is true anytime during or after the link sends the bus request transfer. additionally, the phy will ignore any fair or priority requests if it asserts the receive state while the link is requesting the bus. the link will then reissue the request one clock after the next interface idle. the cycle master uses a normal priority request to send a cycle start message. after receiving a cycle start, the link can issue an isochronous bus request. when arbitration is won, the link proceeds with the isochronous transfer of data. the isochronous request will be cleared by the phy once the link sends another type of request or when the isochronous transfer has been completed. the immreq request is issued when the link needs to send an acknowledgment after reception of a packet address to it. this request must be issued during packet reception. this is done to minimize the delays that a phy would have to wait between the end of a packet and the transmittal of an acknowledgment. as soon as the packet ends, the phy immediately grants access of the bus to the link. the link will send an acknowledgment to the sender unless the header crc of the packet turns out to be bad. in this case, the link will release the bus immediately; it will not be allowed to send another type of packet on this grant. to guarantee this, the link will be forced to wait 160 ns after the end of the packet is received. the phy then gains control of the bus and the ack with the crc error is sent. then the bus is released and allowed to proceed with another request. although highly improbable, it is conceivable that the two separate nodes will believe that an incoming packet is intended for them. the nodes then issue a immreq request before checking the crc of the packet. since both phys will seize control of the bus at the same time, a temporary, localized collision of the bus will occur somewhere between the competing nodes. this collision would be interpreted by the other nodes on the network as being a `zz' line state, not a bus reset. as soon as the two nodes check the crc, the mistaken node will drop its request and the false line state will be removed. the only side effect would be the loss of the intended acknowledgment packet (this will be handled by the higher-layer protocol). 19.4 read/write requests when the link requests to read the specified register contents, the phy will send the contents of the register to the link through a status transfer. if an incoming packet is received while the phy is transferring status information to the link, the phy will continue to attempt to transfer the contents of the register until it is successful. for write requests, the phy will load the data field into the appropriately addresses register as soon as the transfer has been completed. the link will be allowed to request read or write operations at any time. 19.5 status a status transfer is initiated by the phy when it has status information to transfer to the link. the phy will wait until the interface is idle before starting the transfer. the transfer is initiated by asserting the following on the control pins: ctl[0:1] = 01 along with the first two bits of status information on the d[0:1] pins. the phy maintains ctl[0:1] = 01 for the duration of status transfer. the phy may prematurely end a status transfer by asserting something other than ctl[0:1] = 01 on the control pins. this could be caused by an incoming packet from another node. the phy will continue to attempt to complete the transfer until the information has been successfully transmitted. there must be at least one idle cycle in between consecutive status transfers. the phy normally sends just the first four bits of status to the link. these bits are status flags which are needed by the link state machines. the phy sends an entire status packet to the link after a request transfer which contains a read request, or when the phy has pertinent information to send to the link or transaction layers. the only defined condition when the phy automatically sends a register to the link is after self-id, when it sends the physical-id register which contains the new node address. the definition of the bits in the status transfer are shown below.
philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 16 20.0 status request, length of stream: 16 bits bit(s) name description 0 arbitration reset gap indicates that the phy has detected that the bus has been idle for an arbitration reset gap time (this time is defined in the p1394 standard). this bit is used by the link in its busy/retry state machine. 1 subaction gap indicates that the phy has detected that the bus has been idle for a subaction gap time (this time is defined in the p1394 standard). this bit is used by the link to detect the completion of an isochronous cycle. 2 bus reset indicates that the phy has entered the bus reset state. 3 state time out or cps indicates that the phy stayed in a particular state for too long a period, which is usually the effect of a loop in the cable topology, or that the cable power has dropped below the threshold for reliable operation. 47 address these bits hold the address of the phy register whose contents will be transferred to the link. 815 data the data that is to be sent to the link. 21.0 status transfer timing 00 01 01 sv00233 phy ctl [0:1] 01 00 00 00 s[0,1] s[2,3] phy d [0:1] s[14,15] 00 00 figure 9. status transfer timing
philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 17 22.0 transmit when the link wants to transmit information, it will first request access to the bus through the lreq pin. once the phy receives this request, it will arbitrate to gain control of the bus. when the phy wins ownership of the serial bus, it will grant the bus to the link by asserting the `transmit' state on the ctl pins for at least one sysclk cycle, followed by idle for one clock cycle. the link will take control of the bus by asserting either `hold' or `transmit' on the ctl lines. `hold' is used by the link to keep control of the bus if it needs some time to prepare the data for transmission. the phy will keep control of the bus for the link by asserting a `data-prefix' state on the bus. it is not necessary for the link to use `hold' if it is ready to transmit as soon as bus ownership is granted. when the link is prepared to send data, it will assert `transmit' on the ctl lines as well as sending the first four bits of the packet on the d[0:3] lines (assuming 200 mb/s). the `transmit' state is held on the ctl pins until the last bits of data have been sent. the link will then assert `idle' on the ctl lines for one clock cycle after which it releases control of the interface. however, there will be times when the link will need to send another packet without releasing the bus. for example, the link may want to send consecutive isochronous packets or it may want to attach a response to an acknowledgment. to do this, the link will assert `hold' instead of `idle' when the first packet of data has been completely transmitted. `hold', in this case, informs the phy that the link needs to send another packet without releasing control of the bus. the phy will then wait a set amount of time before asserting `transmit'. the link can then proceed with the transmittal of the second packet. after all data has been transmitted and the link has asserted `idle' on the ctl pins, the phy will assert its own `idle' state on the ctl lines. when sending multiple packets in this fashion, it is required that all data be transmitted at the same speed. this is required because the transmission speed is set during arbitration and since the arbitration step will be skipped, there will be no way of informing the network of a change in speed. the pdi1394p11a includes a digital camera/single port phy interoperability enhancement. when a node is root (and consequently cycle master) and is sending isochronous data, it does not need to arbitrate for the bus (by default it would win any such arbitration). this fact was overlooked by some early 100 mbps single port phy manufacturers whose chips are too slow to handle the absence of the arbitration time. this causes their phys to see a header crc error and the packet to be discarded. the pdi1394p11a compensates for this by extending the data_prefix time before sending the packet. this makes the pdi1394p11a fully compatible with all existing 100 mbps phys on the market. 22.1 transmit timing waveforms 00 phy ctl [0:1] 11 00 zz zz zz zz zz 00 sv00235 zz zz zz 0000 phy d [0:3] 0000 0000 zzzz zzzz zzzz zzzz zzzz 0000 zzzz zzzz zzzz zz link ctl [0:1] zz zz 10 10 00 01 01 zz 10 10 00 zzzz link d [0:3] zzzz zzzz p 2 p n 0000 0000 0000 zzzz p 0 p 1 0000 zz phy ctl [0:1] zz zz zz zz zz 00 zz 11 00 zz 00 zzzz phy d [0:3] zzzz zzzz zzzz zzzz zzzz 0000 zzzz 0000 0000 zzzz 0000 10 link ctl [0:1] 10 01 01 01 10 zz 00 zz zz 10 zz p n1 link ctl [0:1] p n 0000 0000 0000 p 0 zzzz 0000 zzzz zzzz p 1 zzzz note: zz = high impedance state p 0 ? p n = packet data note: zz = high impedance state p0 => pn = packet data figure 10. transmit timing waveforms
philips semiconductors preliminary specification pdi1394p11a 3-port physical layer interface 1999 mar 10 18 23.0 receive when data is received by the phy from the serial bus, it will transfer the data to the link for further processing. the phy wil l assert `receive' on the ctl lines and `1' on each d pin. the phy indicates the start of the packet by placing the speed code on the data bus. the p hy will then proceed with the transmittal of the packet to the link on the d lines while still keeping the `receive' status on the ctl pins. once the packet has been completely transferred, the phy will assert `idle' on the ctl pins which will complete the receive operation. note : the speed is a phy-link protocol and not included in the crc. 23.1 receive timing waveforms sv00234 00 phy ctl [0:1] 10 10 10 00 10 10 10 00 0000 phy d [0:3] 1111 p 1 p n 0000 1111 spd p 0 0000 note: spd = speed code p 0 ? p n = packet data note: spd = speed code p 0 pn = packet data figure 11. receive timing waveforms the speed code for the receiver is as follows: d [0:3] data rate (mbit/s) 00xx 100 0100 200 note: x transmitted as 0, ignored on receive. 24.0 power class bits in selfid packet the settings of the pc[0:2] pins appear in the pwr field of the selfid packet. bit 21 is transmitted first, followed by bit 22 and then bit 23. pwr[21:23] description 000 node does not need power and does not repeat power. 001 node is self powered, and provides a minimum of 15 w to the bus. 010 node is self powered, and provides a minimum of 30 w to the bus. 011 node is self powered, and provides a minimum of 45 w to the bus. 100 node may be powered from the bus, and is using up to 1 w. 101 node may be powered from the bus, and is using up to 1 w. an additional 2 w is needed to enable the llc and higher layers. 110 node may be powered from the bus, and is using up to 1 w. an additional 5 w is needed to enable the llc and higher layers. 111 node may be powered from the bus, and is using up to 1 w. an additional 9 w is needed to enable the llc and higher layers.
