ESCRIPTION
The ICS889832 is a high speed 1-to-4 Differential-
to-LVDS Fanout Buffer and is a member of the
HiPerClockS™
HiPerClockS
™
family of high performance
clock solutions from ICS. The ICS889832 is
optimized for high speed and very low output
skew, making it suitable for use in demanding applications
such as SONET, 1 Gigabit and 10 Gigabit Ethernet, and
Fibre Channel. The internally terminated differential input
and V
REF
_
AC
pin allow other differential signal families
such as LVPECL, LVDS, and SSTL to be easily interfaced
to the input with minimal use of external components. The
device also has an output enable pin which may be useful
for system test and debug purposes. The ICS889832 is
packaged in a small 3mm x 3mm 16-pin VFQFN package
which makes it ideal for use in space-constrained
applications.
