These output signals are used to indicate some sort of fault condition within
the Transmit Output signal path.
This output pin will toggle "High" anytime the Transmit Drive Monitor cir-
cuitry either, via the corresponding MTIP and MRING input pins or inter-
nally, detects no bipolar pulses via the Transmit Output line signal (e.g., via
the TTIP_n and TRING_n output pins) for 128 bit-periods.
This output pin will be driven "Low" anytime the Transmit Drive Monitor cir-
cuitry has detected at least one bipolar pulse via the Transmit Output line
signal within the last 128 bit periods.
Hardware Mode: Transmit Clock Invert
Host Mode: Serial Clock Input:
Hardware mode
This input pin is used to select the edge of the TxCLK_n input that the
Transmit Section of all channels will use to sample the TPDATA_n and
TNDATA_n input pins.
Setting this input pin “High” configures all three Transmitters to sample the
TPData_n and TNData_n data on the rising edge of the TxClk_n .
Setting this input pin “Low” configures all three Transmitters to sample the
TPData_n and TNData_n data on the falling edge of the TxClk_n .
Host Mode
In the Host Mode this pin functions as SClk input pin please refer to the pin
descriptions for the Microprocessor interface.
