DESCRIPTION
The SY58018U is a 2.5V/3.3V precision, high-speed, 2:1
differential MUX capable of handling clocks up to 4GHz
and data up to 5Gbps.
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 800mV, 100k
compatible, LVPECL, with extremely fast rise/fall times
guaranteed to be less than 110ps.
The SY58018U operates from a 2.5V ±5% supply or a
3.3V ±10% supply and is guaranteed over the full industrial
temperature range of –40°C to +85°C. For applications that
require CML outputs, consider the SY58017U or for 400mV
LVPECL outputs the SY58019U. The SY58018U is part of
Micrel’s high-speed, Precision Edge™ product line.
All support documentation can be found on Micrel’s web
site at www.micrel.com.

Notes:
8. High frequency AC parameters are guaranteed by design and characterization.
9. 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-to-input skew
does not include the output skew.
10. 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.
11. RJ is measured with a K28.7 comma detect character pattern, measured at 10.7Gbps and 2.5Gbps/3.2Gbps.
12. DJ is measured at 2.5Gbps/3.2Gbps, with both K28.5 and 223 – 1 PRBS pattern.
13. 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.
14. 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.
15. Crosstalk is measured at the output while applying two similar frequencies that are asynchronous with respect to each other at the inputs.
