Features:
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.
Specifications:
Supply Voltages: VDD = 3.3V ±0.3V
Frequency range: 14.318 MHz
≤ Fin ≥ 80 MHz
Cyc to Cyc jitter: <150ps
Output duty cycle 45-55%
Guarantees +85°C operational condition.
