[AK2504A]
MS0143-E-01 - 12 - 2004/01
Logic Data Interface
AK2504A can handle Positive/Negative data and NRZ data.
Positive/Negative data Interface
If NRZ pin = Low, the transmitter accepts Positive/Negative transmit data on TPDATA/TNDATA and the receiver
outputs Positive/Negative received data on RPDATA/RNDATA. In this mode, B3ZS/HDB3 Encoder/Decoder is
disable. Transmit and Received data is output transparently.
NRZ data Interface
If NRZ pin = High, the transmitter accepts NRZ transmit data on TPDATA (TNDATA should be tied to VSS).
The receiver outputs NRZ received data on RPDATA. In this mode, B3ZS/HDB3 Encoder/Decoder is enable.
LCV alarm will be indicated on RNDATA whenever a bipolar violation is detected in the incoming data stream.

Line Code Violation
If a bipolar violation not corresponding to the appropriate coding rule or a code error is detected in the incoming
data stream, LCV is set high for one bit period. The violation pulse corresponding to the appropriate coding rule is
removed from the incoming data.
