SPREAD SPECTRUM CLOCK SYNTHESIZER
Description
The ICS650-41 is a spread spectrum clock synthesizer
intended for video projector applications. It generates 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. For the 50 MHz output, the modulation rate is
50 kHz.
In addition to the EMI optimized clock signal, the device
generates a 48 MHz clock for USB.
