DS1080L Spread-Spectrum Crystal Multiplier General Description Features The DS1080L is a low-jitter, crystal-based clock gener- Generates Spread-Spectrum Clocks from 16MHz ator with an integrated phase-locked loop (PLL) to gen- to 134MHz erate spread-spectrum clock outputs from 16MHz to Selectable Clock Multiplier Rates of 1x, 2x, and 4x 134MHz. The device is pin-programmable to select the clock multiplier rate as well as the dither magnitude. Center Spread-Spectrum Dithering The DS1080L has a spread-spectrum disable mode Selectable Spread-Spectrum Modulation and a power-down mode to conserve power. Magnitudes of 0.5%, 1.0%, and 1.5% Spread-Spectrum Disable Mode Applications Low Cycle-to-Cycle Jitter Automotive Power-Down Mode with High-Impedance Output Cable Modems Low Power Consumption Cell Phones 3.0V to 3.6V Single-Supply Operation Computer Peripherals -40C to +125C Temperature Operation Copiers Small 8-Lead SOP Package Infotainment PCs Printers Ordering Information Pin Configuration PART TEMP RANGE PIN-PACKAGE DS1080LU+ -40C to +125C 8 SOP TOP VIEW DS1080LU/V+ -40C to +125C 8 SOP DS1080LU/V+T -40C to +125C 8 SOP + DS1080LU+T -40C to +125C 8 SOP X1 1 8 X2 +Denotes a lead(Pb)-free/RoHS-compliant package.
