GENERAL DESCRIPTION
The ICS87952I is a low voltage, low skew LVCMOS/
LVTTL clock generator and a member of the
HiPerClockS family of High Performance Clock
Solutions from ICS. With output frequencies up to
180MHz, the ICS87952I is targeted for high
performance clock applications. Along with a fully integrated PLL,
the ICS87952I contains frequency configurable outputs and an
external feedback input for regenerating clocks with “zero delay”.
For test and system debug purposes, the nPLL_EN input al-
lows the PLL to be bypassed. When HIGH, the MR/nOE input
resets the internal dividers and forces the outputs to the high
impedance state.
The low impedance LVCMOS/LVTTL outputs of the ICS87952I
are designed to drive terminated transmission lines. The effec-
tive fanout of each output can be doubled by utilizing the ability
of each output to drive two series terminated transmission lines.
