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