ICS180-51

Low EMI Clock Generator

Description

The ICS180-51 generates a low EMI output clock from

a clock or crystal input. The device uses ICS’

proprietary mix of analog and digital Phase-Locked

Loop (PLL) technology to spread the frequency

spectrum of the output, thereby reducing the frequency

amplitude peaks by several dB.

The ICS180-51 offers center spread selection of

+/-0.625% and +/-1.875%. Refer to the MK1714-01/02

for the widest selection of input frequencies and

multipliers.

ICS offers a complete line of EMI reducing clock

generators. Consult us when you need to remove

crystals and oscillators from your board.

Features

•

Pin and function compatible to Cypress W180-51

Packaged in 8-pin SOIC

Provides a spread spectrum output clock

Accepts a clock input and provides same frequency

dithered output

•

Input frequency of 8 to 28 MHz

•

Peak reduction by 7dB - 14dB typical on 3rd - 19th

odd harmonics

•

Spread percentage selection for +/-0.625% and

+/-1.875%

•

Operating voltage of 3.3 V and 5 V

•

Advanced, low-power CMOS process
