The transmitter and receiver are implemented by differential circuits to increase signal to noise ratio (SNR). The nominal
differential line pulse amplitude at 100
termination is 750 mV, zero to peak. Transformers with 2:1 turn ration are needed at
transmitter and receiver for voltage level translation and DC isolation.
To meet the electrical characteristic requirements in I.430, some additional circuits are needed. At the transmitter side, the
external resistors (18 to 33
) are used to adjust the output pulse amplitude and to meet the transmitter active impedance (
20
) when transmitting binary zeros. At the receiver side, the 1.8 k
resistors protect the device inputs, while the 10 k
resistors
(1.8 k
+8.2 k
) limit the peak current in impedance tests. The diode bridge is used for overvoltage protection.
