ICS181-52

DATASHEET LOW EMI CLOCK GENERATOR ICS181-52 Description The ICS181-52 generates a low EMI output clock from a clock or crystal input. The device uses IDT’s proprietary mix of analog and digital Phase Locked Loop (PLL) technology to spread the frequency spectrum of the output, thereby reducing the frequency amplitude peaks by several dB. The ICS181-52 offers center spread selection of +/-0.625% and +/-1.875%. Refer to the MK1714-01/02 for the widest selection of input frequencies and multipliers. IDT offers a complete line of EMI reducing clock generators. Consult us when you need to remove crystals and oscillators from your board. Features Pin and function compatible to Cypress W181-52 Packaged in 8-pin SOIC Provides a spread spectrum output clock Accepts a clock input and provides same frequency dithered output Input frequency of 28 to 48 MHz for Clock input Peak reduction by 7dB - 14dB typical on 3rd - 19th odd harmonics Spread percentage selection f...
