PRELIMINARY DATASHEET
SPREAD SPECTRUM CLOCK GENERATOR
MK5818
IDT SPREAD SPECTRUM CLOCK GENERATOR

MK5818
REV C 051310
Description
The MK5818 generates a low EMI output clock and a
reference clock from a clock or crystal input. The part is
designed to lower EMI through the application of spreading
a clock. Using IDT’ 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 depending on
spread range. The MK5818 offers a range of down spread
from a high speed clock or crystal input. The MK5818
generates one modulated (SSCLK) and unmodulated
(REFCLK) clock and is compatible with Cypress CY25818.
The modulated clock is controlled by the select pin, and the
unmodulated clock has the same frequency as the input
clock or crystal.
