Signal Name
Used to clock out the TXPOS/
TXNRZ and TXNEG outputs. Data
is clocked out on the rising or on
the falling edge of TCLKO
according to settings of bit
LTxCkRis at the Feature2(I)
Control register.
In rail mode or AMI mode, B3ZS/
HDB3/AMI encoder generates the
positive output. In unipolar
mode, generates the NRZ output.
