Instruction Manual

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.
