2.7
TRANSMIT DRIVER POWER SUPPLY
All transmit driver power supplies must be 5.0 V or 3.3 V.
In E1 mode, despite the power supply voltage, the 75 /120 lines
are driven through a pair of 9.5 series resistors and a 1:2 transformer.
In T1 mode, only 5.0 V can be selected, 100 lines are driven
through a pair of 9.1 series resistors and a 1:2 transformer.
In harsh cable environment, series resistors are required to improve
the transmit return loss performance and protect the device from surges
coupling into the device.
2.8
POWER DRIVER FAILURE MONITOR
An internal power Driver Failure Monitor (DFMON), parallel
connected with TTIPn and TRINGn, can detect short circuit failure
between TTIPn and TRINGn pins. Bit SCPB in register GCF decides
whether the output driver short circuit protection is enabled. When the
short circuit protection is enabled, the driver output current is limited to a
typical value: 180 mAp. Also, register DF, DFI and DFM will be available.
When DFMON will detect a short circuit, register DF will be set. With a
short circuit failure detected, register DFI will be set and an interrupt will
be generated on pin INT.
2.9
TRANSMIT LINE SIDE SHORT CIRCUIT
In E1 or T1 with 5 V VDDT, a pair of 9.5 serial resistors connect
with TTIPn and TRINGn pins and limit the output current. In this case,
the output current is a limited value which is always lower than the
typical line short circuit current 180 mAp, even if the transmit line side is
shorted.
