Spread-Spectrum Crystal Multiplier
General Description
The DS1080CL is a low-jitter, crystal-based clock gen-
erator 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.
