Hello, we have done a previous design with DS90UB926 and DS90UB949 with great success.
On a new display board (DS90UB926) we see a noisy and distorted image sometimes. Usually it will go away after a few power cycles.
The only difference we can see from our previous design is the ground vias under the DS90UB926. Previously we used a 3x3 array however in this design there are less an they are scattered.
Can TI confirm noisy/distorted outputs may be a symptom of a poor ground?
