SY89465U Overview
The SY89465U is a low-jitter, 1:10 LVDS fanout buffer with a 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89465Us 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover. In addition, a unique Fail-Safe Input (FSI) protection prevents metastable conditions when the selected input clock...
