6.3.1 Transmit Line Templates
The DS26303 the transmitters can be selected individually to meet the pulse masks for E1 and T1/J1 mode. The
T1/J1 pulse mask is shown in the transmit pulse template and can be configured on an individual LIU basis. The
TIMPRM pin/bit is used to select the internal transmit terminating impedance of 100 /110 for T1/J1 mode or
75 /120 for E1 mode. The T1 pulse mask is shown in
Figure 6-2
and the E1 pulse template is shown in
Figure 6-3
.
