Transmit Line Templates
The DS26334 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
transmit template is selected via the TS[2:0] bits in the TS register. Transmit impedance matching is selected using
the TIMPOFF and the TIMPRM bits of the same register. When transmit impedance matching is enabled TIMPRM
will select between 75
and 120 impedance if an E1 template is selected, and between 100 and 110
impedance if a T1/J1 template is selected. In E1 mode, if 75
is selected via the TIMPRM bit, the output pulse
amplitude will be 2.37V, if 120
is selected via the TIMPRIM bit, the output pulse amplitude will be 3.0V.
The E1 pulse template is shown in Figure 5-7 and the T1 pulse template is shown in Figure 5-6.
