ICS345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 ICS345 field programmable clock synthesizer generates up to nine high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal or clock input. It is designed to replace crystals and crystal oscillators in most electronic systems.
