SPREAD SPECTRUM CLOCK SYNTHESIZER
Description
The ICS650-44 is a spread spectrum clock synthesizer
intended for video projector and digital TV applications. It
generates three copies of an EMI optimized 50 MHz clock
signal (EMI peak reduction of 7 to 14 dB on 3rd through
19th harmonics) through the use of Spread Spectrum
techniques from a 25 MHz crystal or clock input. The
modulation rate is 50 kHz.
