TDATA0 DI Transmit Data - Port 0. In the Unipolar mode, the data to be transmitted

onto the line from port 0 is input at this pin.

42

4

ECE0 DI Encoder Enable - Port 0. In the Unipolar mode, a High on this pin enables

the B8ZS or HDB3 encoder and decoder for port 0.

43

5

BPV0 DO Bipolar Violation - Port 0. In the Unipolar mode this indicator output goes

High when a bipolar violation is received at port 0.

44

6

RDATA0 DO Receive Data - Port 0. In the Unipolar mode, RDATA is a Non-Return-to-

Zero (NRZ) output. RDATA is stable and valid on the rising edge of

RCLK.

34

40 RDATA1 DO Receive Data - Port 1. In the Unipolar mode, RDATA is a Non-Return-to-

Zero (NRZ) output. RDATA is stable and valid on the rising edge of

RCLK.

BPV1 DO Bipolar Violation - Port 1. In the Unipolar mode this indicator output goes

High when a bipolar violation is received at port 1.

ECE1 DI Encoder Enable - Port 1. In the Unipolar mode, a High on this pin enables

the B8ZS or HDB3 encoder and decoder for port 1.

TDATA1 DI Transmit Data - Port 1. In the Unipolar mode, the data to be transmitted

onto the line from port 1 is input at this pin.
