Overview

Description

The 650-41 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.
