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 50½ source

terminated CML, with extremely fast rise/fall times

guaranteed to be less than 60ps.

The SY58034U 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 LVPECL outputs, consider the SY58035U or

SY58036U Multiplexers. The SY58034U 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.
