Bit
Name
Description
7-
Reserved.
6
OE
This bit determines the output of the Line Driver, i.e., the output on the TTIPn and TRINGn pins.
0: High-Z. (default)
1: Normal operation.
5
T_OFF
This bit determines whether the transmitter is powered down.
0: Normal operation. (default)
1: Power down.
4
THZ_OC
This bit determines the output of the Line Driver, i.e., the output on the TTIPn and TRINGn pins when TOC is detected.
0: The output current is limited to 100 mAp-p. (default)
1: The output current is limited to 100 mAp-p within the first 1 ms after the TOC is detected and then the output is in High-Z state
when the TOC is detected for more than 1 ms.
3
T_SING
This bit determines the transmit line interface.
0: Transmit Differential line interface. Both TTIPn and TRINGn are used to transmit signal to the line side. (default)
1: Transmit Single Ended line interface. Only TTIPn is used to transmit signal. TRINGn should be left open.
2 - 0
T_TERM[2:0] These bits select the impedance matching mode of the transmit path to match the cable impedance.
010: The 120
internal impedance matching is selected for E1 120 twisted pair cable (with transformer).
011: The 75
internal impedance matching is selected for E1 75 coaxial cable (with transformer).
110: The 120
internal impedance matching is selected for E1 120 twisted pair cable (transformer-less).
111: The external impedance matching is selected for E1 120
twisted pair cable or E1 75 coaxial cable (with transformer).
