MK1704ALF

LOW EMI CLOCK GENERATOR
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 aclock 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.
