LOW EMI CLOCK GENERATOR
Description
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’s proprietary mixture of analog and
digital Phase Locked Loop (PLL) technology to synthesize
the frequency. It also uses IDT’s 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.
