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, protection, and backplane distribution
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.
