Protection Circuit for Transmitter
Figure 29
Figure 29
The external resistors (5 ... 10 W ) are required in order to adjust the output voltage to the
pulse mask on the one hand and in order to meet the output impedance of minimum 20 W
(transmission of a binary zero according to ITU-T I.430) on the other hand.
Two mutually reversed diode paths protect the device against positive or negative
overvoltages on both lines.
An ideal protection circuit should limit the voltage at the SX pins from – 0.4 V to V
+ 0.4 V. With the circuit In

becoming active if the 96 kHz test signal is applied while no supply voltage is present.
