4.5.4 QRSS Generation

The XRT83SL314 can transmit a QRSS random sequence to a remote location from TTIP/TRING. The

polynomial is shown in Table 12.

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".
