ICS180-51

DATASHEET LOW EMI CLOCK GENERATOR ICS180-51 Description The ICS180-51 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 ICS180-51 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 W180-51 Packaged in 8-pin SOIC Provides a spread spectrum output clock Accepts a clock input and provides same frequency dithered output Input frequency of 8 to 28 MHz Peak reduction by 7dB - 14dB typical on 3rd - 19th odd harmonics Spread percentage selection for +/-0.625% and ...
