Receive Data
in case of LOS
DCO-R
The intrinsic jitter generated in the absence of any input jitter is not more than 0.035 UI.
In digital bipolar line interface mode the clock and data recovery requires HDB3 coded
signals with 50% duty cycle.
5.1.6
The B8ZS line code or the AMI (ZCS, zero code suppression) coding is provided for the
data received from the ternary or the dual-rail interface. All code violations that do not
correspond to zero substitution rules are detected. The detected errors increment the
code violation counter (16 bits length). In case of the optical interface a selection
between the NRZ code and the CMI Code (1T2B) with B8ZS or AMI postprocessing is
provided. If CMI code is selected the receive route clock is recovered from the data
stream. The CMI decoder does not correct any errors. In case of NRZ coding data is
latched with the falling edge RCLKI.
When using the optical interface with NRZ coding, the decoder is bypassed and no code
violations are detected.
Additionally, the receive line interface contains the alarm detection for Alarm Indication
Signal AIS (Blue Alarm) and the loss-of-signal LOS (Red Alarm).
The signal at the ternary interface is received at both ends of a transformer.
