Description

The Si5350C generates free-running and/or synchronized clocks selectable on each

of its outputs. A dual PLL + high resolution MultiSynthTM fractional divider

architecture enables this user-definable custom timing device to generate any of the

specified output frequencies at any of its outputs. This allows the Si5350C to replace

a combination of crystals, crystal oscillators, and synchronized clocks (PLL). Custom

pin-controlled Si5350C devices can be requested using the ClockBuilder web-based

part number utility (www.silabs.com/ClockBuilder).
