Description

LOW EMI CLOCK GENERATOR
The ICS4231-03 generates a low EMI output clockfrom a clock or crystal input. The ICS4231-03 uses IDT'sproprietary mix of analog and digital Phase LockedLoop (PLL) technology to spread the frequencyspectrum 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.

IDT offers a complete line of EMI reducing clockgenerators. Consult us when you need to removecrystals and oscillators from your board.
