DATASHEET  
FIELD PROGRAMMABLE DUAL OUTPUT SS VERSACLOCK SYNTHESIZER  
ICS252  
Description  
Features  
The ICS252 is a low cost, dual-output, field programmable  
clock synthesizer. The ICS252 can generate two output  
frequencies from 314 kHz to 200 MHz using up to two  
independently configurable PLLs. The outputs may employ  
Spread Spectrum techniques to reduce system  
electro-magnetic interference (EMI).  
8-pin SOIC package  
Two addressable registers  
Input crystal frequency of 5 to 27 MHz  
Clock input frequency of 3 to 150 MHz  
Output clock frequencies up to 200 MHz  
Configurable Spread Spectrum Modulation  
Using ICS’ VersaClock software to configure the PLL and  
output, the ICS252 contains a One-Time Programmable  
(OTP) ROM to allow field programmability. Programming  
features include 4 selectable configuration registers.  
Operating voltage of 3.3 V  
Replaces multiple crystals and oscillators  
Controllable output drive levels  
The device employs Phase-Locked Loop (PLL) techniques  
to run from a standard fundamental mode, inexpensive  
crystal, or clock. It can replace multiple crystals and  
oscillators, saving board space and cost.  
Advanced, low-power CMOS process  
Available in RoHS 5 (green) or RoHS 6 (green and lead  
free) compliant package  
The device also has a power-down feature that tri-states the  
clock outputs and turns off the PLLs when the PDTS pin is  
taken low.  
The ICS252 is also available in factory programmed custom  
versions for high-volume applications.
