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 50 compatible differential CML (currentmode 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 (DA01 and DB01) have a unique internal termination design that allows access to the termination network through VT pins. This feature allows the SY55858U  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.
