ICS91730

Features/Benefits

• ICS91730 is a Spread Spectrum Clock targeted for

Mobile PC and LCD panel applications that generates an

EMI-optimized clock signal (EMI peak reduction of 7-14

dB on 3rd-19th harmonics) through use of Spread

Spectrum techniques.

• ICS91730 focuses on the lower input frequency range of

14.318 to 80.00 MHz with a spread modulation of 20kHz

to 40kHz.
