ESCRIPTION
The ICS8523I-03 is a low skew, high perfor-
mance 1-to-4 Differential-to-LVHSTL fanout buffer
HiPerClockS™
and a member of the HiPerClockS family of High
Performance Clock Solutions from ICS. The
ICS8523I-03 has two selectable clock inputs.
The input pairs can accept most standard differential input
levels. The clock enable is internally synchronized to
eliminate runt pulses on the outputs during asynchronous
assertion/deassertion of the clock enable pin.
ICS
Guaranteed output and part-to-part skew characteristics
make the ICS8523I-03 ideal for those applications demand-
ing well defined performance and repeatability.
