PRELIMINARY DATASHEET  
TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS290  
Description  
Features  
The ICS290 field programmable spread spectrum clock  
synthesizer generates up to eight high-quality,  
high-frequency clock outputs including multiple reference  
clocks from a low-frequency crystal input. It is designed to  
replace crystals, crystal oscillators and stand alone spread  
spectrum devices in most electronic systems.  
Packaged as 20-pin TSSOP  
Eight addressable registers  
Replaces multiple crystals and oscillators  
Output frequencies up to 200 MHz at 3.3 V  
Configurable Spread Spectrum Modulation  
Input crystal frequency of 5 to 27 MHz  
Clock input frequency of 3 to 166 MHz  
Up to eight reference outputs  
Up to two sets of four low-skew outputs  
Operating voltages of 3.3 V  
Controllable output drive levels  
TM  
Using ICS’ VersaClock software to configure PLLs and  
outputs, the ICS290 contains a One-Time Programmable  
(OTP) ROM for field programmability. Programming  
features include input/output frequencies, spread spectrum  
amount, eight selectable configuration registers and up to  
two sets of four low-skew outputs.  
Using Phase-Locked Loop (PLL) techniques, the device  
runs 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 Pb (lead) free packaging  
The ICS290 is also available in factory programmed custom  
versions for high-volume applications.
