General Description

The DS1080L is a low-jitter, crystal-based clock gener-

ator with an integrated phase-locked loop (PLL) to gen-

erate spread-spectrum clock outputs from 16MHz to

134MHz. The device is pin-programmable to select the

clock multiplier rate as well as the dither magnitude.

The DS1080L has a spread-spectrum disable mode

and a power-down mode to conserve power.

Applications
