ICS180-01

ICS180-01 www.DataSheet4U.com Low EMI Clock Generator Description The ICS180-01 generates a low EMI output clock from a clock or crystal input. The device uses ICS’ 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 ICS180-01 offers down spread selection of -1.25% and -3.75%. Refer to the MK1714-01/02 for the widest selection of input frequencies and multipliers. ICS 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 W180-01 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 -1.25% and -3.75% Operating voltage of 3.3 V and 5 V Advanced, low-power CMOS process Available in Pb (lead) free package Industrial temperature range available Block Diagram VDD FS2:1 SS% PLL Clock Synthesis and Spread Spectrum Circuitry CLK X1/CLKIN X2 Clock Buffer/ Crystal Oscillator GND MDS 180-01 B 1 l Revision 050405 tel (408 ) 29 7-120 1 l I n t e gra t e d C i r cu i t S y s t e m s l 5 25 Race Street, San Jo se, CA 9 512 6 w w w. i c st . c o m ICS180-01 LOW EMI CLOCK GENERATOR www.DataSheet4U....
