DS1080L
Spread-Spectrum Crystal Multiplier
Ideal for Applications Requiring a Clock with a Precise Center Frequency, Yet Need to Modulate Frequency to Reduce EMI at the Center Frequency and Its Harmonics
|
Status
Active: In Production.
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.
