DS1080LU+

The DS1080LU+ is a spread spectrum crystal multiplier in 8 pin µSOP package. It 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. The PLL can dither the output clock about its centre frequency at a user selectable magnitude. Using the SMSEL(spread spectrum magnitude select) input the user selects the dither magnitude.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from -40°C to 125°C
• Selectable clock multiplier rates of 1x, 2x and 4x
• Centre spread spectrum dithering
• Selectable spread spectrum modulation magnitudes of ±0.5%, ±1.0% and ±1.5%
• Low cycle to cycle jitter
• Supply current is 15mA
