ICS180-03

Low EMI Clock Generator

Description

Features

The ICS180-03 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.

• Pin and function compatible to Cypress W180-03

• Packaged in 8-pin SOIC

• Provides a spread spectrum output clock

• Accepts a clock input and provides same frequency

dithered output

• Input frequency of 15 to 28 MHz

The ICS180-03 offers down spread selection of -1.25%

and -3.75%. Refer to the MK1714-01/02 for the widest

selection of input frequencies and multipliers.

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

odd harmonics

• Spread percentage selection for -1.25% and -3.75%

• Operating voltage of 3.3 V and 5 V

ICS offers a complete line of EMI reducing clock

generators. Consult us when you need to remove

crystals and oscillators from your board.

• Advanced, low-power CMOS process
