Product Summary
The ICS514AM is a LOCO PLL Clock Generator. The ICS514AM 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. Stored in the ICS514AM ROM is the ability to generate 5 different output frequencies, allowing one chip to work in different speed processor systems. The ICS514AM 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.
