ESCRIPTION
The ICS8344-01 is a low voltage, low skew
fanout buffer and a member of the HiPerClockS ™
HiPerClockS™
family of High Performance Clock Solutions from
IDT. The ICS8344-01 has two selectable clock in-
puts. The CLKx, nCLKx pairs can accept most
standard differential input levels. The ICS8344-01 is designed
to translate any differential signal level to LVCMOS/LVTTL lev-
els. The low impedance LVCMOS/LVTTL outputs are designed
to drive 50Ω series or parallel terminated transmission lines.
The effective fanout can be increased to 48 by utilizing the
ability of the outputs to drive two series terminated lines.
Redundant clock applications can make use of the dual clock
inputs which also facilitate board level testing. The clock
enable is internally synchronized to eliminate runt pulses on
the outputs during asynchronous assertion/deassertion of the
clock enable pin. The outputs are driven low when disabled.
The ICS8344-01 is characterized at full 3.3V, full 2.5V and mixed
3.3V input and 2.5V output operating supply modes.
