Configuration
SDI mode provides the non-bonded (×1) transceiver channel datapath configuration
for HD- and 3G-SDI protocol implementations.
Cyclone IV GX transceivers configured in SDI mode provides the serialization and
deserialization functions that supports the SDI data rates as listed in
SDI functions such as scrambling/de-scrambling, framing, and cyclic redundancy
check (CRC) must be implemented in the user logic.
