LOW EMI CLOCK GENERATOR DATASHEET MK1709 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.
