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
appropriate channel register if this pin is pulled "High". If the TxON pin is
pulled "Low", all 14 transmitters are powered off.
N
OTES
:
1.
TxON is ideal for redundancy applications. See the Redundancy
Applications Section of this datasheet for more details.
2.
Internally pulled "Low" with a 50K
resistor.

Digital Monitor Output (Global Pin for All 14-Channels)
When no transmit output pulse is detected for more than 128 TCLK cycles on
one of the 14-channels, the DMO pin will go "High" for a minimum of one TCLK
cycle. DMO will remain "High" until the transmitter sends a valid pulse.
N
OTE
:
This pin is for redundancy applications to initiate an automatic switch to
the backup card. For individual channel DMO, see the register map.

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 can be selected to send an all ones or an all zero signal by pro-
gramming TCLKCNL. In addition, software control (TCLKE) allows TPOS/
TNEG data to be sampled on either edge of TCLK.
N
OTES
:
1.
TCLKE is a global setting that applies to all 14 channels.
2.
Internally pulled "Low" with a 50k
resistor.

TPOS/TDATA Input
Transmit digital input pin. In dual rail mode, this pin is the transmit positive
data input. In single rail mode, this pin is the transmit non-return to zero (NRZ)
data input.
