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.
