PRELIMINARY
Although HDB3 coding is normally used with single rail NRZ data, the transmit line
encoder accepts either dual rail or single rail data. Bipolar violations in an incoming dual
rail data stream are converted to valid data pulses.
4.2.7
AIS Insertion
An unframed all-ones signal can be inserted into the transmitted data stream. To fulfill
the required accuracy, a reference clock of
±
20 ppm is needed on pin REFCLK.
If local loop configuration and AIS insertion is selected together, the AIS signal is looped
back to RDOP/RDON.
4.3
Framer Interface
The interface to the receive framer is realized by RDOP, RDON and RCLK. Data at
RDOP/N are clocked off with either the rising (RPE
=
1) or falling edge (RPE
=
0) of RCLK.
Alternatively a single rail signal can be selected to be output on pin RDOP (DR/SR
=
0).
Bipolar violation indications are output on pin RDON/BPV in this case.
Data from the framer interface are sampled at XDIP and XDIN on the active edge of the
XCLK. The active edge can be the rising (XPE
=
1) or falling edge (XPE
=
0) of XCLK.
Alternatively a single rail signal can be used on pin XDIP (DR/SR
=
0).
Note: Selection of dual rail/single rail mode is common to receive and transmit direction.
