MAX3816A
I2C 2-Wire Extender for DDC in DVI,
HDMI, and VGA Interfaces
______________________________________________________________________________________

MAX3816A External to Display, In Parallel
Advantages (See Figure 8)
Medium-long cable reach.
In parallel mode, the MAX3816A is very tolerant of
noncompliant DDC sources and sinks.
The MAX3816A can be turned off if another
MAX3816A or speed-up device is being used on the
same DDC.
The MAX3816A can be turned off without isolating
the display from the source side, letting DDC oper-
ate straight through unassisted or assisted.
Consideration
Long cable reflections can reach display circuits since
the MAX3816A is not used as a buffer between source
and display. Hence, very long cables could cause dou-
ble-clocking at display circuits due to stair-step rise/fall
waveforms due to reflections.
