DESCRIPTION
The SY58034U is a 2.5V/3.3V precision, high-speed 1:6
fanout buffer capable of handling clocks up to 6GHz. A
differential 2:1 MUX input is included for redundant clock
switchover applications.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows the device 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 50Ω source
terminated CML, with extremely fast rise/fall times
guaranteed to be less than 60ps.
s Unique input termination and VT pin accepts DC-
The SY58034U operates from a 2.5V ±5% supply or a
coupled and AC-coupled inputs (CML, PECL, LVDS) 3.3V ±10% supply and is guaranteed over the full industrial
s Unique input isolation design minimizes crosstalk
temperature range of –40°C to +85°C. For applications that
s Internal 50Ω output source termination
require LVPECL outputs, consider the SY58035U or
SY58036Uwww.DataSheet4U.com Multiplexers. The SY58034U is part of Micrel’s
s 400mV CML output swing (RL = 50Ω)
high-speed, Precision Edge™ product line.
s –40°C to +85°C temperature range
All support documentation can be found on Micrel’s web
s Available in 32-pin (5mm × 5mm) MLF™ package

Notes:
8. High frequency AC electricals are guaranteed by design and characterization.
9. Output-to-output skew is measured between outputs under identical input conditions.
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. 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.
12. Random jitter is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps to 3.2Gbps.
13. 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.
14. Crosstalk is measured at the output while applying two similar clock frequencies that are asynchronous with respect to each other at the inputs.
