General Description

The ICS85314I-11 is a low skew, high performance 1-to-5

Differential-to-2.5V, 3.3V LVPECL fanout buffer. The ICS85314I-11

has two selectable differential clock inputs. The CLK0, nCLK0 and

CLK1, nCLK1 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

ICS85314I-11 ideal for those applications demanding well defined

performance and repeatability.
