LOCO™ PLL CLOCK GENERATOR
IDT™ / ICS™ LOCO™ PLL CLOCK GENERATOR
Description
The ICS513 LOCO
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 100 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.
