Notes:
1. DNP (Do Not Populate).
2. The value of the series resistors on video data, clock, and timing
connections should be determined by board signal integrity test.
3. For analog power and ground isolation refer to PCB layout guide.
4. For impedance controlled signal layout refer to PCB layout guide.
