DATASHEET

LOW EMI CLOCK GENERATOR

Description

The ICS181-02 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 ICS181-02 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.

IDT offers a complete line of EMI reducing clock

generators. Consult us when you need to remove

crystals and oscillators from your board.

ICS181-02
