4.5.1
ATAOS (Automatic Transmit All Ones)
If ATAOS is selected by programming the appropriate global register, an AMI all ones signal will be transmitted
for each channel that experiences an RLOS condition. If RLOS does not occur, the ATAOS will remain inactive
until an RLOS on a given channel occurs. A simplified block diagram of the ATAOS function is shown in
FIGURE 17. SIMPLIFIED BLOCK DIAGRAM OF THE ATAOS FUNCTION
4.5.2
QRSS/PRBS Generation
The XRT83VSH314 can transmit a QRSS/PRBS random sequence to a remote location from TTIP/TRING. To
select QRSS or PRBS, see the register map for programming details. The polynomial is shown in Table 9.
4.6
Transmit Pulse Shaper and Filter
If TCLK is not present, pulled "Low", or pulled "High" the transmitter outputs at TTIP/TRING will automatically
send an all ones or an all zero signal to the line by programming the appropriate global register. By default, the
transmitters will send all zeros. To send all ones, the TCLKCNL bit must be set "High".
4.6.1
T1 Short Haul Line Build Out (LBO)
The short haul transmitter output pulses are generated using a 7-Bit internal DAC (6-Bit plus the MSB sign bit).
The line build out can be set to interface to five different ranges of cable attenuation by programming the
appropriate channel register. The pulse shape is divided into eight discrete time segments which are set to
fixed values to comply with the pulse template. The short haul LBO settings are shown in Table 10.
