DATASHEET  
TRIPLE PLL FIELD PROGRAMMABLE SS VERSACLOCK SYNTHESIZER ICS345  
Description  
Features  
The ICS345 field programmable clock synthesizer  
generates up to nine high-quality, high-frequency clock  
outputs including multiple reference clocks from a  
low-frequency crystal or clock input. It is designed to  
replace crystals and crystal oscillators in most electronic  
systems.  
Packaged as 20-pin SSOP (QSOP) (Pb-free)  
Spread spectrum capability  
Eight addressable registers  
Replaces multiple crystals and oscillators  
Output frequencies up to 200 MHz at 3.3 V  
Input crystal frequency of 5 to 27 MHz  
Input clock frequency of 2 to 50 MHz  
Up to nine reference outputs  
TM  
Using IDT’s VersaClock software to configure PLLs and  
outputs, the ICS345 contains a One-Time Programmable  
(OTP) ROM to allow field programmability. Programming  
features include eight selectable configuration registers, up  
to two sets of four low-skew outputs, and optional Spread  
Spectrum outputs.  
Up to two sets of four low-skew outputs  
Operating voltages of 3.3 V  
Advanced, low-power CMOS process  
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.  
For one output clock, use the ICS341. For two output  
clocks, see the ICS342. For three output clocks, see the  
ICS343. For more than three outputs, see the ICS348.  
The ICS345 is also available in factory programmed custom  
versions for high-volume applications.
