Overview
Rev 1; 3/06 Spread-Spectrum Crystal Multiplier General Description The DS1080L is a low-jitter, crystal-based clock generator with an integrated phase-locked loop (PLL) to generate 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.
Features ♦ Generates Spread-Spectrum Clocks from 16MHz to 134MHz ♦ Selectable Clock Multiplier Rates of 1x, 2x, and 4x ♦ Center Spread-Spectrum Dithering ♦ Selectable Spread-Spectrum Modulation Magnitudes of ±0.
5%, ±1.
0%, and ±1.
