Si51211 Data Sheet

Three Output Factory Programmable Clock Generator

KEY FEATURES

The factory programmable Si51211 is a low power, small 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 3 outputs up to 170 MHz. The device is factory pro-

grammed 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.

• Generates up to 3 CMOS clock outputs

from 3 to 170 MHz

• Accepts crystal or reference clock input

• 3 to 165 MHz reference clock input

• 8 to 48 MHz crystal input

• Programmable FSEL, SSONb, PD, and OE

input functions

Applications

• Digital still camera

• IP phone

• Crystal/XO replacement

• EMI reduction

• Smart meter

• Portable devices
