SINGLE-CHANNEL CROSSTALK (NOTES 1, 5, 9–11)
7 x 75Ω
Connect LOAD to +5V (internal 400Ω loads on at all outputs).
Program any one input to connect to any one output. See Table 1 or 2 for programming codes.
Turn on the buffer at the selected output (Table 1 or 2).
Drive the selected input with V
Program each numbered input to connect to the same numbered output (IN0 to OUT0, IN1 to OUT1, etc., for the MAX4456;
also IN4 to OUT0, IN5 to OUT1, etc., for the MAX4360.) See Table 1 or 2 for programming codes.
Turn off all output buffers (Table 1 or 2).
Drive all inputs with V
Isolation (in dB) = 20log
Turn on all output buffers (Table 1 or 2).
