General Description

The ICS8546-01 is a low skew, high performance 1-to-6 Crystal

Oscillator-to-LVDS Fanout Buffer. The ICS8546-01 has selectable

crystal, single ended or differential clock inputs. The single-ended

clock input accepts LVCMOS or LVTTL input levels and translate

them to LVDS levels. The CLK1, nCLK1 pair can accept most

standard differential input levels. The output enable is internally

synchronized to eliminate runt pulses on the outputs during

asynchronous assertion/ deassertion of the clock enable pin.

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

ICS8546-01 ideal for those applications demanding well defined

performance and repeatability.
