The ICS8523I-03 is a low skew, high performance 1-to-4
Differential-to-LVHSTL fanout buffer. The ICS8523I-03 has
two selectable clock inputs.The input pairs can accept most
standard differential input levels. The clock enable is
internally synchronized toeliminate runt pulses on the
outputs during asynchronousassertion/deassertion of the
clock enable pin.
Guaranteed output and part-to-part skew characteristics
make the ICS8523I-03 ideal for those applications
demanding well defined performance and repeatability.
