DESCRIPTION

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 50Ω 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

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.

APPLICATIONS

SONET/SDH optical transport

Backplane redundancy

Add-drop Multiplexers
