ESCRIPTION
The ICS853006 is a low skew, high performance
1-to-6 Differential-to-2.5V/3.3V LVPECL/ECL
HiPerClockS™
Fanout Buffer and a member of the HiPerClock ™
S
family of High Performance Clock Solutions from
ICS. The ICS853006 is characterized to operate
from a 2.5V or a 3.3V power supply. Guaranteed output and
part-to-part skew characteristics make the ICS853006 ideal
for those applications demanding well defined performance
and repeatability.
