12.3 Concerning the maximum current consumption of the
DDC (DP_PWR) power supply
DDC power (DP_PWR in case of DisplayPort output) is supplied to the outputs of the VG-870B/871B.
The maximum currents supplied by the DDC power supply are as listed below.
• HDMI output: 0.050 A for each channels
• DVI output: 0.5 A total for 2 channels
• LVDS 4-channel output: 0.5 A total for channels 1 to 4, and max. 0.5 A per channel
• Parallel output (2 channels): 0.5 A total for channels 1 and 2, and max. 0.5 A per channel
• TV encoder output: 0.5 A total for all channels
• PC analog output: 0.5 A total for all channels
• DisplayPort output: 0.5 A total for all channels
1)
The DDC supply voltage is output as shown in the figure below.
DDC power supply output circuit
2)
The supply voltage differs depending on the output connector.
• HDMI output: Fixed at 5 V.
• DVI output: Fixed at 5 V.
• LVDS output: Can be switched between 5 V and 3.3 V using a rear panel switch.
• Parallel output: Can be switched between 5 V, 3.3 V, 2.5 V and 1.8 V using a rear panel switch.
• TV encoder output: Fixed at 5 V.
• PC analog output: Fixed at 5 V.
• DisplayPort output: Fixed at 3.3 V.
• The DDC power supply incorporates an overcurrent protection device, but do
not use a current which exceeds the rating.
• Do NOT supply power to the DDC power supply from the device connected to
the VG. If such the voltage of such a power supply is connected, both the VG
and the connected device may fail.
