SY89846U Description

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 significantly below 100mV). The differential input includes Micrel’s unique, 3-pin internal termination architecture that can...
