NOTICE - The following device(s) are recommended alternatives:

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.
