GENERAL DESCRIPTION

The ICS8752 is a low voltage, low skew LVCMOS clock

generator. With output frequencies up to 240MHz, the

ICS8752 is targeted for high performance clock applcations.

Along with a fully integrated PLL, the ICS8752 contains

frequency configurable outputs and an external feedback

input for regenerating clocks with “zero delay”.

Dual clock inputs, CLK0 and CLK1, support redundant clock

applications. The CLK_SEL input determines which refer-

ence 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 ICS8752 are

designed to drive ter minated transmission lines. The

effective fanout of each output can be doubled by

utilizing the ability of each output to drive two series

terminated transmission lines.

FEATURES

• Fully integrated PLL

• Eight LVCMOS outputs, 7Ω typical output impedance

• Selectable LVCMOS CLK0 or CLK1 inputs for

redundant clock applications

(all outputs are the same frequency)

• Output skew: 100ps (maximum)

• Bank skew: 55ps (maximum)

• Full 3.3V or 2.5V supply voltage

• 0°C to 70°C ambient operating temperature
