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.
Key Features
Accepts a high-speed input and provides a precision ÷3 and ÷5 sub-rate, LVPECL output.
Fail-Safe Input.
Prevents oscillations when input is invalid.
Guaranteed AC performance over temperature and supply voltage:.

ternal Termination General Description 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 unique, 3-pin internal termination architecture that allows the input to interface to any differential signal (AC- or DCcoupled) as small as 100mV (200mVPP) without any level shifting or termination resistor networks in the signal path. The outputs are 800mV, 100Kcompatible LVPECL with fast ri
