Overview
SY89844U Precision LVDS Runt Pulse Eliminator 2:1 MUX with 1:2 Fanout and Internal Termination General Description The SY89844U is a low jitter LVDS, 2:1 input multiplexer (MUX) optimized for redundant source switchover applications.
Unlike standard multiplexers, the SY89844U unique 2:1 Runt Pulse Eliminator (RPE) 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 DC voltage (voltage between the pins of the differential input drops below 100mV).
The differential input includes Micrel’s unique, 3-pin input termination architecture that allows customers to in...
