DATA SHEET  
ICS270  
Triple PLL Field Programmable  
VCXO Clock Synthesizer  
Description  
Features  
Packaged as 20-pin TSSOP  
The ICS270 field programmable VCXO 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 and crystal oscillators in  
most electronic systems.  
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  
Up to eight reference outputs  
TM  
Using ICS’ VersaClock software to configure PLLs  
Up to two sets of four low-skew outputs  
Operating voltages of 3.3 V  
and outputs, the ICS270 contains a One-Time  
Programmable (OTP) ROM for field programmability.  
Programming features include VCXO, eight selectable  
configuration registers and up to two sets of four  
low-skew outputs.  
Controllable output drive levels  
Advanced, low-power CMOS process  
Available in Pb (lead) free packaging  
Using Phase-Locked Loop (PLL) techniques, the  
device runs from a standard fundamental mode,  
inexpensive crystal, or clock. It can replace VCXOs,  
multiple crystals and oscillators, saving board space  
and cost.  
The ICS270 is also available in factory programmed  
custom versions for high-volume applications.
