ICS514MT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 ICS514 LOCO™ is the most cost effective way to generate a high quality, high frequency clock output from a 14.31818 MHz crystal or clock input. The name LOCO stands for LOw Cost Oscillator, as it is designed to replace crystal oscillators in many electronic systems. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard, inexpensive crystal to produce output clocks up to 66.66 MHz.
