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 are requested using the ClockBuilder web-

based utility (www.silabs.com/ClockBuilder).

Functional Block Diagram

 Generates up to 8 non-integer-related

frequencies from 8 kHz to 160 MHz

 Exact frequency synthesis at each

output (0 ppm error)

 Highly linear VCXO gain (kv)

 Glitchless frequency changes

 Configurable Spread Spectrum

selectable at each output

 User-configurable control pins:



Output Enable (OEB_0/1/2)



Power Down (PDN)



Frequency Select (FS_0/1)



Spread Spectrum Enable (SSEN)

 Supports static phase offset

 Rise/fall time control

 Operates from a low-cost, fixed

frequency AT-cut, non-pullable

crystal: 25 or 27 MHz

 Separate voltage supply pins:



Core VDD: 2.5 V or 3.3 V



Output VDDO: 2.5 V or 3.3 V

 Excellent PSRR eliminates external

power supply filtering

 Low output period jitter: 100 ps pp

 Very low power consumption

(<40 mA)

 Available in 3 packages types:



10-MSOP: 3 outputs



24-QSOP: 8 outputs



20-QFN (4x4 mm): 8 outputs
