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 most electronic systems. Using Phase-Locked Loop (PLL) techniques, the device uses a standard, inexpensive crystal to produce output clocks up to 66.66 MHz. Stored in the chip’s ROM is the ability to generate five different output frequencies, allowing one chip to work in different speed processor systems. The device also has a power-down mode that turns off the clock outputs when both select pins are low. In this mode, the internal PLL is not running.
