General Description

The DS1080CL is a low-jitter, crystal-based clock generator with an integrated phase-locked loop (PLL) to generate spread-spectrum clock outputs from 8MHz to 64MHz. The device is pin programmable to select the clock multiplier rate as well as the dither magnitude. The DS1080CL has a spread-spectrum disable mode and a power-down mode to conserve power.
