SKYWORKS SI51214-B11522-GMR

The factory programmable Si51214 is the industry’s lowest power, smallest footprint and frequency flexible programmable clock generator targeting low power, low cost and high volume consumer and embedded applications. The device operates from a single crystal or an external clock source and generates 1 to 2 outputs up to 133 MHz. The device is factory programmed to provide customized output frequencies and control input such as frequency select, spread spectrum on, power down and output enable. Center spread spectrum can also be programmed to reduce EMI to meet board level system requirements.
