Integrated Device Technology Spread Spectrum Clock Generator MK5818SLF

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.
