The gain of the Transmit Amplifier, set by RS , determines
the programmed impedance of the device. The capacitor
CFB blocks the DC component of the loop current. The
ground symbols in the model represent AC grounds, not
actual DC potentials.
The Sense Amplifier is configured as a 4 input differential
amplifier with a gain of 3/4. The voltage at the output of the
sense amplifier (VSA) is calculated using superposition.
VSA1 is the voltage resulting from V1, VSA2 is the voltage
resulting from V2 and so on (reference Figure 4).
Where
∆V is equal to I
MRSENSE (RSENSE = 20Ω)
The voltage at VTX is equal to:
VTR is defined in Figure 4, note polarity assigned to VTR:
Setting VIN equal to zero in EQ 18, defining ZO = -VTR/∆IM
and substituting it into EQ18 will enable the user to
determine the required feedback to match the line
impedance at V2W as shown in Equation 19.
2-Wire Impedance Matching
ZO is the source impedance of the device and is defined as.
ZL is the line impedance and RP is the external protection
resistor. RS is defined as:
