Description

The MK1707D generates a low EMI output clock from a crystal clock input. The part is designed to dither the LCD interface clock for flat panel graphics controllers. The device uses ICS’ 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 MK1707D offers centered spread from a wide range of input clock frequencies. ICS offers many other clocks for computers and computer peripherals. Consult ICS when you need to replace multiple crystals and oscillators from your board.
