Notes
1) In addition to the above test circuit:
Apply VIN JUN1 and measure VOUT TX2 and VOUT JUN1.
Apply VIN JUN2 and measure VOUT TX1 and VOUT JUN1
Apply VIN RX2 and measure VOUT TX1 and VOUT JUN1.
2) All ground connections are star configured (i.e., single
point ground).
CT (Crosstalk) calculation
Examples:
CT = 20xlog (VIN RX1/VOUT JUN2)
CT = 20xlog (VIN RX1/VOUT TX2)
