2.2 Line Interfaces
The transmitted line signals are shown in
output sequence are shown. Separate signal pins provide the appropriate output
signal for positive and negative pulses. The outputs are a full clock period wide
and change on positive clock transitions of the TCLKO pin. For additional
information on the TXPOS and TXNEG outputs refer to Transmitter Outputs in
the Transmitter Operation section in this chapter
however, this encoding can be disabled to send AMI data without any zero code
suppression. Transmit NRZ data, prior to B3ZS/HDB3 encoding, is also available
on the RDAT[7]/TXNRZ pin when parallel mode is not selected and on the
RXCCK/TXNRZ pin when PPDLONLY mode is selected.
