General Description
The MAX3816A DDC*/I2C extender automatically compensates for excess load capacitance of long DVI™, HDMI™, and VGA cables. A single MAX3816A placed at the display side of the link restores signal integrity bidirectionally for both DDC clock and data over 0 to 60 meters of cable.
FEATUREs
