The MK5814C device generates a low EMI output clock from a clock or crystal input. The device is designed to dither a high emissions clock to lower EMI in consumer applications. Using IDT's proprietary mix of analog and digital Phase Locked Loop (PLL) technology, the device spreads the frequency spectrum of the output and reduces the frequency amplitude peaks by several dB. The MK5814C offers both centered and down spread from a high-speed clock input. The multiplier is a fixed 4x. For different multiplier configurations, use the MK5811C (1x) or MK5812 (2x). IDT offers many other clocks for computers and computer peripherals. Consult IDT when you need to remove crystals and oscillators from your board.
