Integrated Circuit Systems ICS513
The ICS513 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. The device also has a power down mode that turns off the clock outputs when both select pins are low.| Part No. | ICS513 |

DESCRIPTION
Using Phase-Locked-Loop (PLL) techniques, the device uses a standard, inexpensive crystal to produce output clocks up to 100 MHz. Stored in the chip’s ROM is the ability to generate 5 different output frequencies, allowing one chip to work in different speed processor systems. In this mode, the internal PLL is not running.
