Description

e Si5350A is a user-definable custom clock generator that is ideally suited for

replacing crystals and crystal oscillators in cost-sensitive applications. Based on a

PLL + high resolution fractional divider MultiSynth

architecture, the Si5350A can

generate any frequency up to 160 MHz on each of its outputs with 0 ppm error.

Spread spectrum is selectable (on/off) on any of the outputs. Custom pin-controlled

Si5350A devices can be requested using the ClockBuilder web-based part number

utility (www.silabs.com/ClockBuilder).
