Line Side Output Circuits
Figure 12 illustrates the output circuit required for operating the MRT device for a 34368 kbit/s application. The
transformer and resistors shown assure that the output waveform meets the CCITT mask for 34368 kbit/s
transmission and that the MRT device is operated within the current limits of the TTL24mA output parameters
on page 10. The transformer should have a frequency response of 0.1 - 100 MHz with an insertion loss of 1dB,
maximum.

Figure 13 shows a variation of the circuit in Figure 12. This circuit improves performance in applications when
a plastic device is mounted in a socket. The additional low-pass filter compensates for possible overshoot
caused by inductance created by the device/socket interface. The transformer should have a frequency
response of 0.1 - 100 MHz with an insertion loss of 1dB, maximum.
Figure 13. Line Side Output Circuit Outline (34368 kbit/s)
The peak voltage and current output requirements for 6312 and 8448 kbit/s operation are different from that
required for 34368 kbit/s operation. The output circuit in Figure 14 illustrates the output circuit required for
6312 kbit/s and 8448 kbit/s operation. The transformer should have a frequency response of .01 - 50 MHz with
an insertion loss of 1dB, maximum. The transformer, drivers and resistors assure that the output waveform
meets the CCITT masks for these rates and that the MRT device is operated within the current limits of the
TTL24mA output parameters on page 10.
