MK1709 - Low EMI Clock Generator

General Description

The MK1709 generates a low EMI output clock from a clock input.

The part is designed to dither the LCD interface clock for flat panel graphics controllers.

Key Features

  • Packaged in 8-pin SOIC (MK1709S) and in 8-pin TSSOP (MK1709AG).
  • 8-pin TSSOP available in lead (Pb) free package Provides a spread spectrum output clock Supports flat panel controllers Guaranteed to +85°C operation Accepts a clock input, provides same frequency dithered output.
  • Good for all VGA modes from 80 to 167 MHz.
  • Peak reduction by 7dB - 14dB typical on 3rd - 19th odd harmonics.

MK1709 Low EMI Clock Generator Description The MK1709 generates a low EMI output clock from a clock input. The part is designed to dither the LCD interface clock for flat panel graphics controllers. 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 MK1709 offers centered spread from a high speed clock input. Refer to the MK1714-01/02 for a crystal input and the widest selection of input frequencies and multipliers. ICS offers many other clocks for computers and computer peripherals. Consult us when you need to remove crystals and oscillators from your board.
