kr 19-6068; Rev 1; 10/11 Spread-Spectrum Crystal Multiplier 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.
Features ♦ Generates Spread-Spectrum Clocks from 8MHz to 64MHz ♦ Selectable Clock Multiplier Rates of 1x, 2x, and 4x ♦ Center Spread-Spectrum Dithering ♦ Selectable Spread-Spectrum Modulation Magnitudes of ±0.
