SY89846U Datasheet (Micrel Semiconductor)

SY89846U, LVPECL 1:5 Fanout

The SY89846U is a 2.5/3.3V, 1:5 LVPECL fanout buffer with a 2:1 differential input multiplexer (MUX).

A unique Fail-Safe Input (FSI) protection prevents metastable output conditions when the selected input clock fails to a DC voltage (voltage between the pins of the differential input drops signific
