Si51210 Data Sheet Two Output Factory Programmable Clock Generator KEY FEATURES The factory programmable Si51210 is the industrys lowest power, smallest footprint and frequency flexible programmable clock generator targeting low power, low cost and Generates up to 2 CMOS clock outputs from 3 to 170 MHz 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 170 MHz. The Accepts crystal or reference clock input device is factory programmed to provide customized output frequencies and control 3 to 165 MHz reference clock input input such as frequency select, spread spectrum on, power down and output enable. 8 to 48 MHz crystal input Center spread spectrum can also be programmed to reduce EMI to meet board level Programmable FSEL, SSONb, PD, and system requirements.
