Three implementations external to the display such as
external box products or cable assemblies are shown
in Figures 6, 7, and 8.
• 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

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,

MAX3816As can be used in parallel as an input mux
to display, with only one “on” at a time.
