General Description

The ICS85304I-01 is a low skew, high performance 1-to-5

Differential-to-3.3V LVPECL fanout buffer. The ICS85304I-01 has

two selectable clock inputs. The CLKx, nCLKx pairs can accept most

standard differential input levels. The clock enable is internally

synchronized to eliminate runt clock pulses on the outputs during

asynchronous assertion/ deassertion of the clock enable pin.

Guaranteed output and part-to-part skew characteristics make the

ICS85304I-01 ideal for those applications demanding well defined

performance and repeatability.

Features
