If the signals are not used:
All these SDVO signals may be left open.
Remarks:
For the DDC signals, a voltage translator to 3.3V or 5V is needed.
Pair to Pair spacing: Pair to Pair matching: BUS to BUS spacing:
35mil = 0.9mm better than 25mm 20mil = 0.5mm
The AC coupling capacitors (100nF / 0402) must be placed near the device for the Tx signals only. The maximum number of vias per signal is less than 4.
Supported devices:
SiliConImage SIL1362 / SIL1364 (DVI)
Chrontel CH7021 (SDTV / HDTV / CRT)
EMV/EMI filters:
Chokes are needed.
