The differential input includes Micrel's unique, 3-pin input termination architecture that allows customers to interface to any differential signal (AC- or DC-coupled) as small as 100mV without any level shifting or termination resistor networks in the signal path. The outputs are 50 source terminated CML, with extremely fast rise/fall times guaranteed to be less than 60ps. The SY58017U operates from a 2.5V 5% supply or a 3.3V 10% supply and is guaranteed over the full industrial temperature range of -40C to +85C. For applications that require LVPECL outputs, consider the SY58018U or SY58019U Multiplexers with LVPECL outputs. The www..com SY58017U is part of Micrel's high-speed, Precision EdgeTM APPLICATIONS product line. s Redundant clock distribution All support documentation can be found on Micrel's web site at www.micrel.com. s OC-3 to OC-192 SONET/SDH clock/data distribution s Loopback s Fibre Channel distribution FUNCTIONAL BLOCK DIAGRAM IN0 50 VT0 50 /IN0 MUX IN1 50 VT1 50 /IN1 1 S TYPICAL PERFORMANCE 10.7Gbps Output 0 /Q0 SEL (TTL/CMOS) Output Swing (100mV/div.)

Tape and Reel. 16-Pin MLFTM PIN DESCRIPTION Pin Number 1, 2 3, 4 Pin Name IN0, /IN0 IN1, /IN1 Pin Function Differential Input: These input pairs are the differential signal inputs to the device. They accept differential AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally terminates to a VT pin through 50. Note that these inputs will default to an indeterminate state if left open. Please refer to the "Input Interface Applications" section for more details. Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin. The VT0 and VT1 pins provide a center-tap to a termination network for maximum interface flexibility. See "Input Interface Applications" section for more details. This single-ended TTL/CMOS compatible input selects the inputs to the multiplexer. Note that this input is internally connected to a 25k pull-up resistor and will default to a logic HIGH state if left open. No connect. Positive Power Supply: Bypass with 0.1F0.01F low ESR capacitors. 0.01F capacitor should be as close to VCC pin as possible. Differential Outputs: This CML output pair is the output of the device. Normally terminate with 100 across Q and /Q. See "Output Interface Applications" section. It is a logic function of the IN0, IN1, and SEL inputs. Please refer to the "Truth Table" for details.

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. Due to the limited drive capability, use for input of the same package only. 4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential (GND) on the PCB. JB uses 4-layer JA in still-air measurment, unless otherwise stated. 5.

High-frequency AC parameters are guaranteed by design and characterization. 10. Input-to-input skew is the difference in time from and input-to-output in comparison to any other input-to-output. In addition, the input-input skew does not include the output skew. 11. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the respective inputs. 12. RJ is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps. 13. DJ is measured at 2.5Gbps/3.2Gbps, with both K28.5 and 223-1 PRBS pattern. 14. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, Tn-Tn-1 where T is the time between rising edges of the output signal. 15. Total jitter definition: with an ideal clock input of frequency fMAX, no more than one output edge in 1012 output edges will deviate by more than the specified peak-to-peak jitter value. 16. Crosstalk is measured at the output while applying two similar frequencies that are asynchronous with respect to each other at the inputs.
