max4355 16 x 16 nonblocking video crosspoint switch with i/o buffers ______________________________________________________________________________________ 29 detailed description the max4355 is a highly integrated 16 ? 16 nonblock- ing video crosspoint switch matrix. all inputs and out-puts are buffered, with all outputs able to drive standard 75 reverse-terminated video loads. a 3-wire interface programs the switch matrix and ini-tializes with a single update signal. the unique serial interface operates in one of two modes: complete matrix mode (mode 1) or individual output address mode (mode 0). in the functional diagram, the signal path of the max4355 is from the inputs (in0 in15), through the switching matrix, buffered by the output amplifiers, andpresented at the output terminals (out0 out15). the other functional blocks are the serial interface and con-trol logic. each of the functional blocks is described in detail below. analog outputs the max4355 outputs are high-speed voltage feed-back amplifiers capable of driving 150 (75 back-ter- minated) loads. the gain, a v = +1v/v or +2v/v, is selectable through programming bit 4 of the serial con-trol word. amplifier compensation is automatically opti- mized to maximize the bandwidth for each gain selec-tion. each output can be individually enabled and dis- abled through bit 5 of the serial control word. when disabled, the output is high impedance, presenting typ- ically a 4k load, and 3pf output capacitance, allowing multiple outputs to be connected together in buildinglarge arrays. on power-up (or asynchronous reset ), all outputs are initialized in the disabled state to avoidoutput conflicts in large-array configurations. the pro- gramming and operation of the max4355 is output referred. outputs are configured individually to connect to any one of the 16 analog inputs, programmed to the desired gain (a v = +1v/v or +2v/v), or disabled in a high-impedance state. analog inputs the max4355 offers 16 analog input channels. eachinput is buffered before the crosspoint switch matrix, allowing one input to cross-connect to up to 16 outputs. the input buffers are voltage feedback amplifiers with high-input impedance and low-input bias current. this allows the use of very simple input clamp circuits. max4355 16 x 16 switch matrix power-on reset serial interface thermal shutdown decode logic disable all outputs latches 256 16 16 matrix register 96 bits update register 16 bits enable/disable a v * a v * a v * a v * *a v = +1v/v or +2v/v a0?3 mode in0in1 in2 in15 din sclk update ce reset out0out1 out2 out15 v cc v ee dgnd v dd doutaout agnd functional diagram downloaded from: http:///
max4355 16 x 16 nonblocking video crosspoint switch with i/o buffers 30 ______________________________________________________________________________________ switch matrix the max4355 has 256 individual t-switches making a16 x 16 switch matrix. the switching matrix is 100% nonblocking, which means that any input may be rout- ed to any output. the switch matrix programming is output referred. each output may be connected to any one of the 16 analog inputs. any one input can be rout- ed to all 16 outputs with no signal degradation. digital interface the digital interface consists of the following pins: din,dout, sclk, aout , update , ce , a3 a0, mode, and reset . din is the serial data input; dout is the serial data output. sclk is the serial data clock that clocksdata into the data input registers (figure 2). data at din is loaded at each falling edge of sclk. dout is the data shifted out of the 96-bit complete matrix mode (mode = 1). din passes directly to dout when in individual output address mode (mode = 0). the falling edge of update latches the data and pro- grams the matrix. when using individual outputaddress mode, the address recognition output aout drives low when control word bits d13 to d10 matchthe address programming inputs (a3 a0) and update is low. table 1 is the operation truth table. programming the matrix the max4355 offers two programming modes:individual output address mode and complete matrix mode. these two distinct programming modes are selected by toggling a single mode pin high or low. both modes operate with the same physical board lay- out. this flexibility allows initial programming of the ic by daisy-chaining and sending one long data word while still being able to address immediately and update individual outputs in the matrix. individual output address mode (mode = 0) drive mode to logic low to select mode 0. individualoutputs are programmed through the serial interface ce update sclk din dout mode aout reset operation/comments 1 x x x x x x 1 no change in logic. 01 d i d i-96 11 1 data at din is clocked on the negativeedge of the sclk into the 96-bit complete matrix mode register. dout supplies original data in 96 sclk pulses later. 00xxx111 data in the serial 96-bit completematrix mode register is transferred into parallel latches that control the switching matrix. 01 d i d i 01 1 data at din is routed to the individualoutput address mode shift register. din is also connected directly to dout so that all devices on the serial bus may be addressed in parallel. 00xd i d i 00 1 the 4-bit chip address a 3 to a 0 is compared to d 13 to d 10 . if equal, the remaining 10 bits in the individualoutput address mode register are decoded, allowing reprogramming for a single output. aout signals a successful individual matrix update. x x xxxxx 0 asynchronous reset. all outputs aredisabled. other logic remains unchanged. table 1. operation truth table downloaded from: http:///

disabled. the out-puts may be enabled by sending a new 96-bit data word or a 16-bit individual output address word. a reset is initiated from any of three sources. reset can be driven low by external circuitry to initiate a reset, orreset can be pulled low by internal circuitry during power-up (power-on reset) or thermal shutdown. since driving reset low only clears the output buffer enable bit in the matrix control latches, reset can be used to disable all outputs simultaneously. if no newdata has been loaded into the 96-bit complete matrix mode register, a single update restores the previous matrix control settings. power-on reset the power-on reset ensures all output buffers are in adisabled state when power is initially applied. a v dd voltage comparator generates the power-on reset.when the voltage at v dd is less than 2.5v, the power- on-reset comparator pulls reset low through internal circuitry. as the digital supply voltage ramps up cross-ing 2.5v, the max4355 holds reset low for 40ns (typ). connecting a small capacitor from reset to dgnd extends the power-on-reset delay. see reset delay vs. reset capacitance in the typical operating characteristics. thermal shutdown the max4355 features thermal shutdown protectionwith temperature hysteresis. when the die temperature exceeds +150 c, the max4355 pulls reset low, dis- abling the output buffers. when the die cools by 20 c, the reset pulldown is deasserted, and output buffers remain disabled until the device is programmed again. applications information building large video-switching systems the max4355 can be easily used to create largerswitching matrices. the number of ics required to implement the matrix is a function of the number of input channels, the number of outputs required, and whether the array needs to be nonblocking. the most straightforward technique for implementing nonblock- ing matrices is to arrange the building blocks in a grid. the inputs connect to each vertical bank of devices in parallel with the other banks. the outputs of each build- ing block in a vertical column connect together in a wired-or configuration. figure 6 shows a 128-input, 32-output, nonblocking array using the max4355 16 x 16 crosspoint devices. the wired-or connection of the outputs shown in the diagram is possible because the outputs of the ic devices can be placed in a disabled or high-imped- ance output state. this disable state of the outputbuffers is designed for a maximum impedance vs. fre- quency while maintaining a low-output capacitance. these characteristics minimize the adverse loading effects from the disabled outputs. larger arrays are constructed by extending this connection technique to more devices. driving a capacitive load figure 6 shows an implementation requiring many out-puts to be wired together. this creates a situation where each output buffer sees not only the normal load impedance, but also the disabled impedance of all the other outputs. this impedance has a resistive and a capacitive component. the resistive components reduce the total effective load for the driving output. total capacitance is the sum of the capacitance of all the disabled outputs and is a function of the size of the matrix. also, as the size of the matrix increases, the length of the pc board traces increases, adding more capacitance. the output buffers have been designed to drive more than 30pf of capacitance while still main- taining a good ac response. depending on the size of the array, the capacitance seen by the output can exceed this amount. there are several ways to improve the situation. the first is to use more building-block crosspoint devices to reduce the number of outputs that need to be wired together (figure 7). in figure 7, the additional devices are placed in a sec- ond bank to multiplex the signals. this reduces the number of wired-or connections. another solution is to put a small resistor in series with the output before the capacitive load to limit excessive ringing and oscilla- tions. figure 8 shows the graph of the optimal isolation resistor vs. capacitive load. a lowpass filter is created from the series resistor and parasitic capacitance to ground. a single r-c does not affect the performance at video frequencies, but in a very large system there may be many r-cs cascaded in series. the cumulative effect is a slight rolling off of the high frequencies caus- ing a "softening" of the picture. there are two solutions to achieve higher performance. one way is to design the pc board traces associated with the outputs such that they exhibit some inductance. by routing the traces in a repeating "s" configuration, the traces that are nearest each other exhibit a mutual inductance increas- ing the total inductance. this series inductance causes the amplitude response to increase or peak at higher frequencies, offsetting the rolloff from the parasitic capacitance. another solution is to add a small-value inductor to the output. downloaded from: http:///
max4355 36 ______________________________________________________________________________________ crosstalk signal and board routing issues improper signal routing causes performance problemssuch as crosstalk. the max4355 has a typical crosstalk rejection of -62db at 6mhz. a bad pc board layout degrades the crosstalk rejection by 20db or more. to achieve the best crosstalk performance: 1) place ground isolation between long critical sig-nal pc board trace runs. these traces act as a shield to potential interfering signals. crosstalk canbe degraded by parallel traces as well as directly above and below on adjoining pc board layers. 2) maintain controlled-impedance traces. design as many of the pc board traces as possible to be 75 transmission lines. this lowers the impedance of thetraces, reducing a potential source of crosstalk. more power is dissipated due to the output buffer driving a lower impedance. 3) minimize ground-current interaction by using agood ground plane strategy. in addition to crosstalk, another key issue of concern isisolation. isolation is the rejection of undesirable feed- through from input to output with the output disabled. the max4355 achieves a -110db isolation at 6mhz by selecting the pinout configuration such that the inputs and outputs are on opposite sides of the package. coupling through the power supply is a function of the quality and location of the supply bypassing. use appropriate low-impedance components and locate them as close as possible to the ic. avoid routing the inputs near the outputs. power-supply bypassing the max4355 operates from a single +5v or dual ?vto ?v supplies. for single-supply operation, connect all v ee pins to ground and bypass all power-supply pins with a 0.1? capacitor to ground. for dual-supplysystems, bypass all supply pins to ground with 0.1? capacitors. power in large systems the max4355 has been designed to operate with splitsupplies down to ?v or a single supply of +5v. operating at the minimum supply voltages reduces the figure 7. 64 x 16 nonblocking matrix with reduced capacitiveloading in (0?5) in (16?1) in (32?7)in (48?3) outputs (0?5) outputs (16?2) 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out in (64?9) in (80 95) in (96?11) in (112?27) max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 max4355 figure 6. 128 x 32 nonblocking matrix using 16 x 16 crosspoint devices in (0?5) in (16?1) in (32?7)in (48?3) outputs (0?5) 16in 16 out 16in 16 out 16in 16 out 16in 16 out 16in 16 out max4355 max4355 max4355 max4355 max4355 16in 16 out max4355 16 x 16 nonblocking video crosspoint switch with i/o buffers downloaded from: http:///
max4355 16 x 16 nonblocking video crosspoint switch with i/o buffers ______________________________________________________________________________________ 37 power dissipation by as much 40% to 50%. at +5v, themax4355 consumes 195mw (0.76mw/point). driving a pc board interconnect or a cable (a v = +1v/v or +2v/v) the max4355 output buffers can be programmed toeither a v = +1v/v or +2v/v. the +1v/v configuration is typically used when driving a short-length (less than3cm), high-impedance "local" pc board trace. to drive a cable or a 75 transmission line trace, program the gain of the output buffer to +2v/v and place a 75 resistor in series with the output. the series terminationresistor and the 75 load impedance act as a voltage- divider that divides the video signal in half. set the gainto +2v/v to transmit a standard 1v video signal down a cable. the series 75 resistor is called the back-match, reverse termination, or series termination. this 75 resistor reduces reflections, and provides isolation,increasing the output-capacitive-driving capability. matrix programming the max4355 s unique digital interface simplifies pro- gramming multiple max4355 devices in an array.multiple devices are connected with dout of the first device connecting to din of the second device, and so on (figure 9). two distinct programming modes, indi- vidual output address mode (mode = 0) and complete matrix mode (mode = 1), are selected by toggling a single mode control pin high or low. both modes oper- ate with the same physical board layout. this allows ini- tial programming of the ic by daisy-chaining and sending one long data word while still being able to address immediately and update individual locations in the matrix. individual output address mode (mode 0) in individual output address mode, the devices areconnected in a serial bus configuration, with the data routing gate (figure 3) connecting din to dout, mak- ing each device a virtual node on the serial bus. a sin- gle 16-bit control word is sent to all devices simultaneously. only the device with the corresponding chip address responds to the programming word, and updates its output. in this mode, the chip address is set through hardware pin strapping of a3 a0. the host then communicates with the device by sending a 16-bitword consisting of 2 don t care msb bits, 4 chip address bits, and 10 bits of data to make the wordexactly 2 bytes in length. the 10 data bits are broken down into 4 bits to select the output to be programmed; 1 bit to set the output enable; 1 bit to set gain; and 4 bits to select the input to be connected to that output. in this method, the matrix is programmed one output at a time. complete matrix mode (mode 1) in complete matrix mode, the devices are connected ina daisy-chain fashion where n x 96 bits are sent to pro- gram the entire matrix, and where n = the number of max4355 devices connected in series. this long data word is structured such that the first bit is the lsb of the last device in the chain and the last data bit is the msb of the first device in the chain. the total length of the data word is equal to the number of crosspoint devices to be programmed in series times 96 bits per crosspoint device. this programming method is most often used at startup to initially configure the switching matrix. +5v single-supply operation with a v = +1v/v and +2v/v the max4355 guarantees operation with single +5vsupply and gain of +1v/v for standard video input sig- nals (1vp-p). to implement a complete video matrix switching system capable of gain = +2v/v while operat- ing with +5v single supply, combine the max4355 crosspoint switch with maxim s low-cost, high-perfor- mance video amplifiers optimized for single +5v supplyoperation (figure 10). the max4450 single and max4451 dual op amps are unity-gain-stable devices that combine high-speed performance with rail-to- rail outputs. the common-mode input voltage range extends beyond the negative power-supply rail (groundin single-supply applications). the max4450 is avail- able in the ultra-small 5-pin sc70 package, while the max4451 is available in a space-saving 8-pin sot23. the max4383 is a quad op amp available in a 14-pin 0 10 5 2015 25 30 0 500 optimal isolation resistance vs. capacitive load capacitive load (pf) isolation resistance ( ) 200 100 300 400 figure 8. optimal isolation resistor vs. capacitive load rail-to-rail is a registered trademark of nippon motorola, ltd. downloaded from: http:///
