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 (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 …
