APPLICATIONS

■Redundantclockdistribution

■AllSONET/SDHclockdistribution

■AllFibreChanneldistribution

■AllGigabitEthernetclockdistribution

The SY58036U 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 400mV LVPECL

(100K temperature compensated), with extremely fast rise/

fall times guaranteed to be less than 80ps.

The SY58036U 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 SY58034U or for 800mV

LVPECL outputs the SY58035U. The SY58036U is part of

Micrel’s high-speed, Precision Edge® product line.
