Note 1:
Connect LOAD (pin 8) to +5V (internal 400
loads on at all outputs).
Note 2:
Program any one input to connect to any one output (see Table 1 or 2 for programming codes).
Note 3:
Turn on buffer at the selected output (see Table 1 or 2).
Note 4:
Drive the selected input with VIN, and measure VOUT at the -3dB frequency at the selected output.
Note 5:
Program each numbered input to connect to the same numbered output (IN0 to OUT0, IN1 to OUT1, etc.).
See Table 1 or 2 for programming codes.
Note 6:
Turn off all output buffers (see Table 1 or 2).
Note 7:
Drive all inputs with VIN and measure VOUT at any output.
Note 8:
Isolation (in dB) = 20log10 (VOUT/VIN).
Note 9:
Turn on all output buffers (see Table 1 or 2).
Note 10:
Drive any one input with VIN and measure VOUT at any undriven output.
Note 11:
Crosstalk (in dB) = 20log10 (VOUT/VIN).
Note 12:
Drive all but one input with VIN and measure VOUT at the undriven output.
