ICS180-51 Datasheet Low Emi Clock Generator

Manufacturer: Renesas

Overview: DATASHEET LOW EMI CLOCK GENERATOR ICS180-51.

General Description

The ICS180-51 generates a low EMI output clock from a clock or crystal input.

The device uses IDT’s 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%.

Key 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 Block Diagram.
