ICS342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 ICS342 is a low cost, dual-output, field programmable clock synthesizer. The ICS342 can generate two output frequencies from 250 kHz to 200 MHz, using up to two independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI).
