DS1080L

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 ±1.5% ♦ Spread-Spectrum Disable Mode ♦ Low Cycle-to-Cycle Jitter ♦ Power-Down Mode with High-Impedance Output ♦ Low Cost ♦ Low Power Consumption ♦ 3.0V to 3.6V Single-Supply Operation ♦ -40°C to +125°C Temperature Operation ♦ Small 8-Lead µSOP Package DS1080L Applications Automotive Cable Modems Cell Phones Computer Peripherals Copiers Infotainment PCs Printers www.DataSheet4U.com Pin Configuration PART DS1080L+ Ordering Information TEMP RANGE -40°C to +125°C PIN-PACKAGE 8 µSOP TOP VIEW X1 GND CMSEL 1 2 8 7 X2 VCC SSO PDN +Denotes lead-free package.
