Product Description (cont’d)
Two N-channel MOSFETs provide the level shifting
function required when the DDC controller or EDID
EEPROM is operated at a lower supply voltage than
the monitor. The gate terminals for these MOSFETS
(VCC_DDC) should be connected to the supply rail (typi-
cally 3.3V, 2.5V etc.) that supplies power to the trans-
ceivers of the DDC controller.

PIN DESCRIPTIONS
DESCRIPTION
This is a supply input for the SYNC_1 and SYNC_2 level shifters, video protection and the
DDC circuits.
Active high enable. Disables the Sync buffer outputs when low.
Video signal ESD protection channel. This pin is typically tied one of the video lines between
the controller device and the video connector.
Video signal ESD protection channel. This pin is typically tied one of the video lines between
the controller device and the video connector.
Video signal ESD protection channel. This pin is typically tied one of the video lines between
the controller device and the video connector.
Ground reference supply pin.
This is an isolated supply input for the DDC_1 and DDC_2 level-shifting N-FET gates.
An external 0.22uF bypass capacitor is required on this pin.
DDC signal input. Connects to the video connector side of one of the DDC lines.signal output.
DDC signal output. Connects to the monitor DDC logic.
