ï® XO replacement

The Si5350A is a highly-flexible, 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 MultiSynthTM architecture, the

Si5350A can generate any frequency up to 200 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).
