Notes:
1. Outputs at integer-related frequencies and using the same driver format. See "3.10.3. Programmable Initial Phase
2. The maximum step size is only limited by the register lengths; however, the MultiSynth output frequency must be kept
between 5 MHz and Fvco/8.
3. Update rate via I2C is also limited by the time it takes to perform a write operation.
4. Default value is 0.5% down spread.
5. Default value is ~31.5 kHz.
