Description

Why does Video Timing Controller Generator reset early in relation to the Blanking Signals, if both the detector and the generator are enabled?

This only happens when the Detector and the Generator are both enabled, and the Detector is set up to only detect the Blanking inputs, but not the Sync inputs.

Solution

This is a known issue in the Video Timing Controller v5.01.a.

It is fixed in the Video Timing Controller v5.01.a Rev2 or later pcore patch, and in the Video Timing Controller v6.0.
