PRELIMINARY
Data Sheet
Transmitter. Dedicated external resistors (10 … 12.5 ) are required for the transmitter
in order to
• Adjust the output voltage to the pulse mask (nominal 750 mV according to ITU-T
• Meet the output impedance of a minimum of 20

Receiver. At the receiver, 8 k
recommended to use two resistors per line, as shown in
possible to place a high resistance between the transformer and the diode protection
circuit (required to pass 96-kHz input impedance test of ITU-T I.430). The remaining
resistor protects the VIP receiver from input current peaks.
