8.2.1.2.10 Step 10: Ramp Compensation Selection

The Ramp compensation is selected to minimize the jitter. Higher ramp gives lower jitter but can worsen the transient response. The ramp compensation selection is a trade off between transient response and jitter.

Table 9 shows the available ramp selections.
