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

External Box or Cable Assembly
Applications
Three implementations external to the display such as
external box products or cable assemblies are shown
in Figures 6, 7, and 8.
MAX3816A External to Display, In Series
Advantages (See Figure 6)
Long cable reach.
The MAX3816A acts as a buffer between the source
and display. Hence, source reflections are isolated
to the source side of the MAX3816A, protecting dis-
play circuits from possible double clocking due to
stair-step waveforms caused by very long cables
with reflections.
The MAX3816A can be turned off (DRVR_EN assert-
ed low) to isolate source and display buses. The dis-
play bus can then operate independently of
source-cable loading or malfunctions. Also, multiple
MAX3816As can be used in parallel as an input mux
to display, with only one “on” at a time.
Consideration
Only one series-connected MAX3816A is allowed on a
bus. Two or more series-connected MAX3816A ICs will
not function. If multiple MAX3816A ICs are expected,
use the parallel applications in Figures 7 and 8.
