6.3 P2 I/O Signal Requirements
6.3.1 VGA
6.3.2 ESD
This section provides the information necessary to interface with the P2 I/O
signals, without using a XVME-9640 RTM module.
For proper operation of the VGA display, 150ohm termination to GND is
required on the CRT_REAR_RED, CRT_REAR_GREEN and CRT_REAR_BLUE
signals. Failure to apply this termination may result in poor display quality
and improper operation of Intel® HD Graphics control panel in Windows®.
Also for proper monitor detection, the REAR_DDC_CLK and REAR_DDC_DATA
lines should be level shifted to +5V. See the following for suggested interface
schematic:
It is strongly suggested that ESD protection be included in interface circuitry
on the VGA and USB ports. Failure to do so may cause damage the XVME-
6500 in the event of an ESD discharge into the I/O pins.
