FIELD PROGRAMMABLE TRIPLE OUTPUT SS VERSACLOCK SYNTHESIZER

Description

The ICS343 is a low cost, triple-output, field programmable

clock synthesizer. The ICS343 can generate three output

frequencies from 250 kHz to 200 MHz, using up to three

independently configurable PLLs. The outputs may employ

Spread Spectrum techniques to reduce system

electro-magnetic interference (EMI).

Using IDT’s VersaClock™ software to configure the PLL

and output, the ICS343 contains a One-Time

Programmable (OTP) ROM to allow field programmability.

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.

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 ICS343 is also available in factory-programmed

custom versions for high-volume applications.
