Description
The Si5350B combines a clock generator and VCXO function into a single device. A
flexible architecture enables this user definable custom timing device to generate
any of the specified output frequencies from either the internal PLL or the VCXO.
This allows the Si5350B to replace multiple crystals, crystal oscillators, and VCXOs.
Custom pin-controlled Si5350B devices can be requested using the ClockBuilder
web-based part number utility: www.silabs.com/ClockBuilder.
