ICS650GI-44T集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 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.
