LOW EMI CLOCK GENERATOR DATASHEET MK5814 The MK5814 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 ICS’ 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 MK5814 offers both centered and down spread from a high-speed clock input. The multiplier is a fixed 4x. For different multiplier configurations, use the MK5811 1x or MK5812 2x . ICS offers many other clocks for computers and computer peripherals. Consult ICS when you need to remove crystals and oscillators from your board.

DATASHEET

MK5814

The MK5814 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 ICS’ 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 MK5814 offers both centered and down spread from a high-speed clock input. The multiplier is a fixed 4x.

For different multiplier configurations, use the MK5811 1x or MK5812 2x .

ICS offers many other clocks for computers and computer peripherals. Consult ICS when you need to remove crystals and oscillators from your board.
