DATASHEET
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.
