11 / 83 page  xr XRT83SL314 14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT REV. 1.0.1 8 TRANSMITTER SECTION NAME PIN TYPE DESCRIPTION TxON AC20 I 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. NOTE: TxON is ideal for redundancy applications. See the Redundancy Applications Section of this datasheet for more details. Internally pulled "Low" with a 50K Ω resistor. DMO Y4 O 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. NOTE: This pin is for redundancy applications to initiate an automatic switch to the backup card. For individual channel DMO, see the register map.

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 the appropriate global register. TPOS/TNEG data can be sampled on either edge of TCLK selected by TCLKE in the appropriate glo- bal register. NOTE: TCLKE is a global setting that applies to all 14 channels.

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. NOTE: Internally pulled "Low" with a 50K Ω resistor. |
