VCO coarse tuning

This chapter describes the algorithm for VCO coarse tuning, which finds the optimum
SWC_VCO[7:0] value.

VCO coarse tuning algorithm goes through 3 following phases:

1.

Initialization: sets the static control words for the synthesizer

2.

Decision:

monitors

the

two

digital

outputs

from

the

synthesizer

(COARSE_STEPDONE and COARSE_COMPO) and makes a decision on the correct
value of every bit of SWC_VCO[7:0]. Input control bit of COARSE_START will be
used to start each cycle.

3.

Normal mode setting: controls are set back to the values needed for normal synthesizer
operation.

Below are two similar algorithms, one for the SXT/SXR and other CGEN. Algorithms differ
mainly in the configuration register addresses.
