Multiplexed chroma signal is input on this bus.
I (Connected to ground.)
- External OSD select input. (Connected to ground.)
- External OSD luma input. (Connected to ground.)
O Test outputs. These pins should be left unconnected for normal operation.
I Active low test input. This pin should be tied to VDD for normal operation.
I Active high test inputs. This pin should all be tied to VSS for normal operation.
Digital power connections. Connect to the digital +3.3 volt power supply
-
and decouple to the digital ground plane.
- Digital ground connections. Connect to the digital ground plane.
Analog current sink return for the video DAC circuits.
-
Connect to the analog ground plane.
- Analog power connections for the clock PLL circuits.
- Analog power connections for the video DAC circuits.
