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 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 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.
IDT offers many other clocks for computers and computer
peripherals. Consult us when you need to remove crystals
and oscillators from your board.
