General Description

The SY55854U is a fully differential, CML, 2 x 2-crosspoint

switch. The non-blocking design allows any input to be

connected to any output. Varying the state of the select

inputs allows SY55854U to be used in backup, fault

tolerant,

applications.

SY55854U inputs can be terminated with a single resistor

between the true and the complement pins of a given

input.

The SY55854U is a member of Micrel’s new SuperLite

family of high-speed logic devices. This family features

very small packaging, high signal integrity, and flexible

supply voltage operation.
