ICS8752  
LOW SKEW, 1-TO-8  
LVCMOS CLOCK MULTIPLIER/ZERO DELAY BUFFER  
GENERAL DESCRIPTION  
FEATURES  
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”.  
Fully integrated PLL  
Eight LVCMOS outputs, 7Ω typical output impedance  
Selectable LVCMOS CLK0 or CLK1 inputs for  
redundant clock applications  
Input/Output frequency range: 18.33MHz to 240MHz  
at VCC = 3.3V 5ꢀ  
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.  
VCO range: 220MHz to 480MHz  
External feedback for “zero delay” clock regeneration  
Cycle-to-cycle jitter: 75ps (maximum),  
(all outputs are the same frequency)  
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.  
Output skew: 100ps (maximum)  
Bank skew: 55ps (maximum)  
The low impedance LVCMOS outputs of the ICS8752 are  
designed to drive terminated 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.  
Full 3.3V or 2.5V supply voltage  
0°C to 70°C ambient operating temperature  
Available in both standard and lead-free RoHS-compliant  
packages

ground.  
LVCMOS CONTROL PINS:  
All control pins have internal pull-ups or pull-downs; additional  
resistance is not required but can be added for additional  
protection. A 1kΩ resistor can be used.
