Product details

Description

The ICS181-51 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.

Features

Pin and function compatible to Cypress W181-51 Packaged in 8-pin SOIC Provides a spread spectrum output clock Accepts a clock input and provides same frequency dithered output.
Input frequency of 28 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.
