5.4.1 Transmit Line Templates
The DS26324 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 TS2-TS0 bits in the
using the TIMPOFF and the TIMPRM bits of the same register. When transmit impedance matching is enabled
TIMPRM will select between 75Ω and 120Ω impedance if an E1 template is selected, and between 100Ω and
110Ω impedance if a T1/J1 template is selected. In E1 mode, if 75Ω is selected via the TIMPRM bit, the output
pulse amplitude will be 2.37V, if 120Ω is selected via the TIMPRIM bit, the output pulse amplitude will be 3.0V.
The E1 pulse template is shown in
