Figure 7.2 W6692 wiring configuration in te applications
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.
