10. Si5338 Registers
This section describes the registers and their usage in detail. These values are easily configured using
ClockBuilder Pro. See AN428 for a working example using Skyworks Solutions' F301 MCU.
10.1. Assembling the Si5338 Register Map
Once all of the desired features have been configured, the values should be collected into a single list in order to
write to the device. Collect register values for the required registers:
1. All MultiSynth, R, and P divider ratios
2. PLL parameters
3. Output driver parameters and multiplexors
4. Input multiplexors
5. Miscellaneous register values
And any additional/optional features:
6. Frequency inc/dec
7. Phase inc/dec
8. Initial phase offset
9. Spread spectrum
10.2. Miscellaneous Register Writes
The following register bits must also be written to ensure proper device functionality.
 Register 47[7:2] = 000101b
 Register 106[7] = 1b
 Register 116[7] = 1b
 Register 42[5] = 1b
 Register 6[7:5] = 000b
 Register 6[1] = 0b
 Register 28[7:6] = 00b
With the register information from 10.1 and 10.2, assemble the register map, and follow the procedure in Figure 9
of the Si5338 data sheet.
