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. (See Section 4.1.1)
3. For analog power and ground isolation refer to PCB layout guide.
4. For critital 3G signal layout refer to PCB layout guide.
5. For impedance controlled signals refer to PCB layout guide.
