ICS503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 ICS503 is a member of the LOCO™ family, the most cost effective way to generate a high quality, high frequency clock output from a low frequency crystal or clock input. The name LOCO stands for LOw Cost Oscillator, as it is designed to replace crystals and crystal oscillators in most electronic systems. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 160 MHz.
