PIN DESCRIPTION

PIN NO.

PIN NAME

DESCRIPTION

HSYNC_OUT

Horizontal sync signal buffer output. Connects to the video connector side of the

horizontal sync line.

HSYNC

Horizontal sync signal buffer input. Connects to the VGA Controller side of the

horizontal sync line.

3, 11

GNDD

Digital ground reference supply pin.

VRGB

VRGB supply pin. This is an isolated supply pin for the R, G and B ESD protection

circuits.

Blue signal video protection channel. This pin is typically tied to the B video line

between the VGA controller device and the video connector.

Green signal video protection channel. This pin is typically tied to the G video line

between the VGA controller device and the video connector.

Red signal video protection channel. This pin is typically tied to the R video line

between the VGA controller device and the video connector.

GNDA

Analog ground reference supply pin.

9, 16

VCC

VCC supply pin. This is the main supply input for the DDC_CLK and DDC_DATA pullup

resistors and ESD protection circuits. It is also connected to the sync buffers and to the

ESD protection diodes present on the HSYNC_OUT and VSYNC_OUT lines.

DDC_DATA

DDC data pin.

DDC_CLK

DDC clock pin.

VAUX

VAUX supply pin. This is the supply input for the 50kΩ pullups connected to the HSYNC

and VSYNC buffer inputs.

VSYNC

Vertical sync signal buffer input. Connects to the VGA Controller side of the vertical

sync line.

VSYNC_OUT

Vertical sync signal buffer output. Connects to the video connector side of the vertical

sync line.
