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