SY89202U - Micrel Semiconductor

SY89202U Precision 1:8 LVPECL Fanout Buffer

The SY89202U is a precision, high-speed, integrated clock divider LVPECL fanout buffer capable of handling clocks up to 1.5GHz. Optimized for communications applications, the three independently controlled output banks are phase matched and can be configured for pass-through (÷1), ÷2 or ÷4 divide ratios. The differential input includes Micrel’s unique, 3-pin.
