I2C 2-Wire Extender for DDC in DVI,

HDMI, and VGA Interfaces

General Description

The MAX3816A DDC*/I2C extender automatically compen-

sates for excess load capacitance of long DVI™, HDMI™,

and VGA cables. A single MAX3816A placed at the dis-

play side of the link restores signal integrity bidirectionally

for both DDC clock and data over 0 to 60 meters of cable.

The MAX3816A features compensation for cable

capacitance with a guaranteed range up to 3000pF,

typically beyond 5000pF. The MAX3816A detects state-

change assertion by the logical “AND” of the source

side and display side. It asserts the new state with a

rail-to-rail slew-rate-limited driver capable of meeting

I2C rise- and fall-time requirements under the full load

of the cable. After assertion of the new state, a holdoff

period of 2.5µs prevents a subsequent state change

while the cable channel settles.

Under full load at 100kbps, the MAX3816A consumes

25mW, excluding pullup resistors. It is available in a

16-pin TSSOP package and operates from 0°C to +70°C.
