Transmit Clock Input
TCLK is the input facility clock used to sample the incoming TPOS/TNEG data. If
TCLK is absent, pulled "Low", or pulled "High", the transmitter outputs at TTIP/
TRING sends an all zero signal to the line. TPOS/TNEG data can be sampled on
either edge of TCLK selected by TCLKE.
N
OTE
:
TCLKE is a global setting that applies to all 8 channels.

Transmit All Ones for Channel
Hardware Mode Only
Setting this pin “High” enables the transmission of an all ones pattern to the line
from TTIP/TRING. If this pin is pulled “Low”, the transmitters operate in normal
throughput mode.
N
OTE
:
Internally pulled “Low” with a 50k
resistor for all channels. This feature is
available in Host mode by programming the appropriate channel register.

Transmit On/Off Input
Upon power up, the transmitters are powered off. Turning the transmitters On or
Off is selected through the microprocessor interface by programming the appropri-
ate channel register while in Host mode. However, if TxONCNTL is set "High" in
the appropriate global register or if in Hardware mode, the activity of the transmitter
outputs is controlled by the TxON pins.
N
OTE
:
TxON is ideal for redundancy applications. See the Redundancy
Applications Section of this datasheet for more details. Internally pulled
"Low" with a 50K
resistor.
