LOW EMI CLOCK GENERATOR The MK5811A 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 MK5811A offers both centered and down spread from a high-speed clock input. For different multiplier configurations, use the MK5812 (2x) or MK5814 (4x).

MK5812S General Description
LOW EMI CLOCK GENERATOR The MK5812 generates a low EMI output clock from a clock or crystal input. The part 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, reducing the frequency amplitude peaks by several dB. The MK5812 offers both centered and down spread from a high speed clock input. The device offers a 2x fixed multiplier.
For different multiplier configurations, use the MK5811 (1x) or the MK5814 (4x).
