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.
