ICS1523MT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

General Description

The ICS1523 is a low-cost, high-performance frequency generator. It is well suited to general purpose phase controlled clock synthesis as well as line-locked and genlocked high-resolution video applications. Using ICS’s advanced low-voltage CMOS mixed-mode technology, the ICS1523 is an effective phase controlled clock synthesizer and also supports video projectors and displays at resolutions from VGA to beyond UXGA.
