Product details

Description

The ICS181-53 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.

Features

Pin and function compatible to Cypress W181-53 Packaged in 8-pin SOIC Provides a spread spectrum output clock Accepts a clock input and provides same frequency dithered output.
Input frequency of 46 to 75 MHz for Clock input.
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 pr.
