Spread Spectrum Clock Generator
PRELIMINARY INFORMATION
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 ICS’ 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.
