LOW EMI CLOCK GENERATOR DATASHEET MK1704A The MK1704A is an upgraded version of the MK1704 and is recommended for all new designs. It offers more reduction in the frequency amplitude peaks and will support frequencies up to 140 MHz. The MK1704A generates a low EMI output clock from a clock input. The part is designed to dither the LCD interface clock or other clocks for flat panel graphics controllers. The MK1704A uses IDT’ proprietary mixture of analog and digital Phase Locked Loop PLL technology to synthesize the frequency. It also uses IDT’ patented technique to spread the frequency spectrum of the output, thereby reducing the frequency amplitude peaks by several dB. IDT offers many other clocks for computers and computer peripherals. Consult IDT when you need to remove crystals and oscillators from your board.

DATASHEET

MK1704A

The MK1704A is an upgraded version of the MK1704 and is recommended for all new designs. It offers more reduction in the frequency amplitude peaks and will support frequencies up to 140 MHz.

The MK1704A generates a low EMI output clock from a clock input. The part is designed to dither the LCD interface clock or other clocks for flat panel graphics controllers. The MK1704A uses IDT’ proprietary mixture of analog and digital Phase Locked Loop PLL technology to synthesize the frequency. It also uses IDT’ patented technique to spread the frequency spectrum of the output, thereby reducing the frequency amplitude peaks by several dB.

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