SY54017AR
Low Voltage 1.2V/1.8V CML 2:1 MUX 3.2Gbps, 2.5GHz
General Description
The SY54017AR is a fully differential, low voltage 1.2V/1.8V CML 2:1 MUX. The SY54017AR can process clock signals as fast as 3.2GHz or data patterns up to 3.2Gbps. The differential input includes Micrel's unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled from a 2.5V driver) as small as 100mV (200mVPP) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an internal voltage reference is provided to bias the VT pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 95ps. The SY54017AR operates from a 2.5V 5% core supply and a 1.8V or 1.2V 5% output supply and is guaranteed over the full industrial temperature range (-40C to +85C). The SY54017AR is part of Micrel's (R) high-speed, Precision Edge product line. Datasheets and support documentation can be found on Micrel's web site at: www.micrel.com.

Pin Description
Pin Number 16,1 4,5 2 3 Pin Name IN0, /IN0 IN1,/IN1 VT0 VT1 Pin Function Differential Inputs: These input pairs are the differential signal inputs to the device. They accept differential signals as small as 100mV (200mVPP). Each input pin internally terminates with 50 to the VT pin. Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin. This pin provides a center-tap to a termination network for maximum interface flexibility. An internal high impedance resistor divider biases VT to allow input AC-coupling. For AC-coupling, bypass VT with a 0.1F low ESR capacitor to VCC. See "Interface Applications" subsection and Figure 2a. This single-ended TTL/CMOS-compatible input selects the inputs to the multiplexer. Note that this input is internally connected to a 25k ohm pull-up resistor and will default to a logic HIGH state if left open. Positive Power Supply: Bypass with 0.1uF//0.01uF low ESR capacitors as close to the VCC pin as possible. Supplies input and core circuitry. Output Supply: Bypass with 0.1uF//0.01uF low ESR capacitors as close to the VCCO pins as possible. Supplies the output buffer. Ground: Exposed pad must be connected to a ground plane that is the same potential as the ground pin. CML Differential Output Pair: Differential buffered copy of the input signal. The output swing is typically 390mV. See "Interface Applications" subsection for termination information.

1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB. yJB and qJA values are determined for a 4-layer board in still-air number, unless otherwise stated. 4. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.

Notes: 6. 7. 8. 9. Input-to-Input skew is the difference in time between both inputs and the output for the same temperature, voltage and transition. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the respective inputs. Random jitter is measured with a K28.7 pattern, measured at fMAX. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2 -1 PRBS pattern.

10. Cycle-to-cycle jitter definition: the variation period between adjacent cycles over a random sample of adjacent cycle pairs. tJITTER_CC = Tn -Tn+1, where T is the time between rising edges of the output signal. 11. Total jitter definition: with an ideal clock input frequency of fMAX (device), no more than one output edge in 10 output edges will deviate by more than the specified peak-to-peak jitter value. 12. Crosstalk induced jitter is defined as the added jitter that results from signals applied to the adjacent channel. It is measured at the output while applying a similar, differential clock frequencies that are asynchronous with respect to each other at the adjacent input.

Interface Applications
For Input Interface Applications, see Figures 4a through 4f and for CML Output Termination, see Figure 5a through Figure 5d. CML Output Termination with VCCO 1.2V For VCCO of 1.2V, Figure 5a, terminate the output with 50-to-1.2V, DC coupled, not 100 differentially across the outputs. If AC-coupling is used, Figure 5d, terminate into 50to-1.2V before the coupling capacitor and then connect to a high value resistor to a reference voltage. Do not AC couple with internally terminated receiver. For example, 50 ANY-IN input. AC-coupling will offset the output voltage by 200mV and this offset voltage will be too low for proper driver operation. CML Output Termination with VCCO 1.8V For VCCO of 1.8V, Figure 5a and Figure 5b, terminate with either 50-to-1.8V or 100 differentially across the outputs. AC- or DC-coupling is fine. Input AC Coupling The SY54017AR input can accept AC-coupling from any driver. Bypass VT with a 0.1F low ESR capacitor to VCC as shown in Figures 4c and 4d. VT has an internal high impedance resistor divider as shown in Figure 2a, to provide a bias voltage for AC-coupling.
