Transmit Bipolar Tip for Transceiver 1 to 16. These pins are differential line
driver tip outputs. These pins can be high impedance if:
If TXENABLE is low, TTIPn/TRINGn will be high impedance. Note that if
TXENABLE is low, the register settings for control of TTIPn/TRINGn are ignored
and output is high impedance.
The differential outputs of TTIPn and TRINGn can provide internal matched
impedance for E1 75 Ω , E1 120 Ω , T1 100 Ω , or J1 110 Ω . The user can turn off
internal termination.
Note: The two pins shown for each transmit bipolar tip (e.g., pins C5 and D5 for
TTIP1) should be tied together.
Transmit Bipolar Ring for Transceiver 1 to 16. These pins are differential line
driver ring outputs. These pins can be high impedance if:
If TXENABLE is low, TTIPn/TRINGn will be high impedance. Note that if
TXENABLE is low, the register settings for control of TTIPn/TRINGn are ignored
and output is high impedance.
The differential outputs of TTIPn and TRINGn can provide internal matched
impedance for E1 75 Ω , E1 120 Ω , T1 100 Ω , or J1 110 Ω . The user can turn off
internal termination.
Note: The two pins shown for each transmit bipolar ring (e.g., pins D6 and E6
for TRING1) should be tied together.
Transmit Enable. If this pin is pulled low, all transmitter outputs (TTIPn and
TRINGn) are high impedance. The register settings for tri-state control of
TTIPn/TRINGn are ignored if TXENABLE is low. If TXENABLE is high, the
particular driver can be tri-stated by the register settings.
