Field Programmable SS VersaClock Synthesizer

ICS251

DATASHEET

Description

Features

The ICS251 is a low cost, single-output, field programmable

clock synthesizer. The ICS251 can generate an output

frequency from 314 kHz to 200 MHz and may employ Spread

Spectrum techniques to reduce system electro-magnetic

interference (EMI).

• 8-pin SOIC package

• Four addressable registers

• Input crystal frequency of 5 to 27 MHz

• Clock input frequency of 3 to 150 MHz

• Output clock frequencies up to 200 MHz

• Configurable Spread Spectrum Modulation

• Operating voltage of 3.3 V

™

Using IDT’s VersaClock software to configure the PLL and

output, the ICS251 contains a One-Time Programmable

(OTP) ROM to allow field programmability. Programming

features include 4 selectable configuration registers.

• Replaces multiple crystals and oscillators

• Controllable output drive levels

The device employs Phase-Locked Loop (PLL) techniques to

run 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 RoHS compliant packaging

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 ICS251 is also available in factory programmed custom

versions for high-volume applications.
