Higher-Order RGB + S ync
V ideo Multiplexing
Higher-order RGB video multiplexers can be realized
by paralleling several MAX463/MAX464s. Connect LE
one in use. Since the disabled output resistance of the
MAX463/MAX464 is 250k
, several devices may be
paralleled to form larger RGB video multiplexer arrays
without signal degradation. Connect series resistors at
each amplifier's output to isolate the disabled output
capacitance of each paralleled device, and use a
MAX469 or MAX470 to drive the output coaxial cables
(see Figure 7).
Paralleling MAX 466s to S witc h
1-of-4 RGB + S ync S ignal Inputs
Figure 8 shows a 1-of-4 RGB + sync video mux/amp
circuit. The 1k
disabled output resistance limits the
number of paralleled MAX465/MAX466s to no more
than two. The amplifier outputs are connected after a
22
isolation resistor and ahead of a 50
back-termi-
nation resistor, which isolates the active amplifier out-
put from the capacitive load (5pF typ) presented by the
inactive output of the second MAX466. Impedance
mismatching is minimal, and the signal gain at the
cable end is near 1. This minimizes ringing in the out-
put signals. For multiplexing more than two devices,
see the section Higher Order RGB + Sync Video
Multiplexing, above.
