The SY55858U is a low-voltage, high-speed dual 2 x 2
crosspoint switch with a flexible input that accepts CML
or PECL, and a 50
compatible differential CML (current-
mode logic) output. The non-blocking design allows any
input to connect to any output. Varying the state of the
select inputs allows SY55858U to be used in backup,
fault tolerant, protection and backplane distribution
applications.
The signal inputs (DA
0–1
and DB
0–1
) have a unique
internal termination design that allows access to the
termination network through V
T
pins. This feature allows
the device to easily interface to other logic standards
such as AC-coupled or DC-coupled PECL/LVPECL
signals. For applications that require a single-channel
2 x 2 crosspoint, consider the SY55854.
