VTxDet - VTxDetO
VNDet = voltage at noise detector output
VRef = reference voltage (about 1.9 V) see figure 2.
VTxDet = Voltage at transmit detector output.
VTxDetO
=
voltage at transmit detector output at the point
when the voltage at the noise detector starts
moving when a signal at transmit channel input is
gradually increased (threshold, typical value 30 mV)
2. Depends on V+. Channels are tracking.
