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 2.5s 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.
