OSDC(0~4) Multiplexed chroma signal is input on this bus.
OSDC(5~9) I (Connected to ground.)
OSDSEL - External OSD select input. (Connected to ground.)
OSDY(0~9) - External OSD luma input. (Connected to ground.)
TEST(03~06)
O Test outputs. These pins should be left unconnected for normal operation.
TEST(00~02)
TESTB I Active low test input. This pin should be tied to VDD for normal operation.
TEST (0~2) 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
VDD -
and decouple to the digital ground plane.
VSS - Digital ground connections. Connect to the digital ground plane.
Analog current sink return for the video DAC circuits.
ISINK -
Connect to the analog ground plane.
AVDD - Analog power connections for the clock PLL circuits.
AVDD - Analog power connections for the video DAC circuits.
