GENERAL DESCRIPTION
The ICS8752I is a low voltage, low skew
LVCMOS clock generator and a member of
the HiPerClockS™ f amily of High Performance
Clock Solutions from ICS. With output fre-
quencies up to 240MHz, the ICS8752I is tar-
geted for high performance clock applications. Along with a
fully integrated PLL, the ICS8752I contains frequency
configurable outputs and an external feedback input for re-
generating clocks with “zero delay”.
Dual clock inputs, CLK0 and CLK1, support redundant clock
applications. The CLK_SEL input determines which reference
clock is used. The output divider values of Bank A and B are
controlled by the DIV_SELA0:1, and DIV_SELB0:1, respectively.
For test and system debug purposes, the PLL_SEL input
allows 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 outputs of the ICS8752I 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 trans-
mission lines.
