Equivalent DC Circuit at LOUT Pins for Calculation of R1 and R2
Series Resistor Calculations
Equation 1
Equation 2
Equation 3
Let R1 = R2
Equation 4
Notes:
N = 2
RL = 50 ohms
VLOUT = 2.326 V
ILOUT = 7.5 mA
Equation 5
Equation 5 should be used to determine the value of R1 and R2 for the particular transformer used by each customer.

Notes:
1. RSEC is the DC impedance of the transformer secondary (IC side of transformer).
2. RPRIM is the DC impedance of the transformer primary (line side of transformer).
3. RCORD is the DC impedance of the TE connecting cord; typically 4–6 ohms.
4. N is the transformer turns ratio (N = 2 for Am79C30A/32A).
5. RL is the S-interface line impedance (50 ohms).
6. ILOUT is the desired load current for the CCITT transmission templates (7.5 mA for 50-ohm line).
7. VLOUT is the nominal output voltage from the DSC/IDC line driver.
