General Description

The SY89837U is a low jitter, low skew, high-speed 1:8 fanout buffer with a unique, 2:1 differential input multiplexer (MUX) optimized for clock redundant switchover applications.

Unlike standard multiplexers, the SY89837U unique 2:1 runt pulse eliminator (RPE) input MUX prevents any short cycles or “runt” pulses during switchover.

In addition, a unique fail-safe input protection prevents metastable conditions when the selected input clock fails to a static DC differential voltage (differential input voltage drops below 200mV).
