PRELIMINARY DATASHEET

TRIPLE PLL FIELD PROGRAMMABLE VCXO CLOCK

Description

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.

Using IDT’s VersaClock

software to configure PLLs 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.

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.
