SY89228U Datasheet (Micrel Semiconductor)

SY89228U, Clock Divider

The SY89228U is a precision, low jitter 1GHz ÷3, ÷5 clock divider with an LVPECL output.

A unique FailSafe Input (FSI) protection prevents metastable output conditions when the input clock voltage swing drops significantly below 100mV or input is removed.

The differential input includes Micrel’s uni
