ESCRIPTION
The ICS8 73034 is a low skew, high perfor-
mance Differential-to-2.5V, 3.3V LVPECL/ECL
Clock Generator a n d a m e m b e r o f t h e
HiPerClockS TM
family of High Perfor mance
Clock Solutions from ICS. The ICS873034
is characterized to operate from either a 2.5V or a 3.3V
power supply. Guaranteed output and par t-to-par t skew
characteristics make the ICS873034 ideal for those
clock distribution applications demanding well defined
perfor mance and repeatability.
F
EATURES
