Description
The ICS4231-03 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 ICS4231-03 offers four different center and down
spread selections. 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 W42C31-03
Packaged in 8-pin SOIC (Pb free available)
Provides a spread spectrum output clock
Accepts a clock or crystal input and provides same
frequency dithered output
Input clock frequency of 10 to 33 MHz
Peak reduction by 8dB - 14dB typical on 3rd - 19th
odd harmonics
Spread percentage selections of ±1.875%, ±1.0%,
and -2.0%
Operating voltage of 5V
Advanced, low-power CMOS process
