The user can refer to the“ SERIALIZER/DESERIALIZER (SERDES) INTERFACE ”section in ADRV9026 user guide to know more about the JESD204B & JESD204C interface, In JESD204C standard. The sync word can contain the following information: 1. Pilot signal (used to mark the borders of the multiblocks and extended multiblocks) 2. CRC-3 signal (used for error detection) 3. CRC-12 signal (used for error detection) 4. FEC signal (used for error detection and correction) 5. Command channel (used for transmitting commands and status information)
ADRV9026 just support the CRC-12 sync word mode. This working mode is not configurable. The CRC-12 in ADRV9026 is just used to report the error and will not do any error correction.
I can’t find it in the user guide, how to configure FEC, please tell me.
What should I do if there is a data error in the 204C debugging process?(Use 26c_nonlinksharing)
We are checking on this. Will get back.
adrv9026_support said:4. FEC signal (used for error detection and correction)
This feature FEC signal (used for error detection and correction) is correctly not supported.
