The ICS181-01LF is a low EMI clock generator that produces a spread spectrum output clock from a clock or crystal input. It utilizes a combination of analog and digital Phase-Locked Loop (PLL) technology to minimize frequency amplitude peaks, achieving a peak reduction of 7dB to 14dB on odd harmonics from the 3rd to the 19th. The device supports input frequencies ranging from 28 MHz to 75 MHz and offers selectable down spread percentages of -1.25% and -3.75%. This clock generator is pin and function compatible with the Cypress W181-01 and is packaged in an 8-pin SOIC format. It operates at supply voltages of 3.3 V or 5 V and is available in an industrial temperature range of -40¬8C to +85¬8C. The ICS181-01LF requires minimal external components, including a decoupling capacitor, and is designed for optimal performance with specific PCB layout recommendations to reduce EMI.
