Re: [casper] VDIF Packetizer

[Wael Farah]

Dear all, Very interested in this discussion and in both the VDIF and VITA49 packet formats for RFSoCs. Open-sourcing the blocks would definitely be welcome!

I also plan to write one for VITA49.2.

Opening the source would be very welcome! Thanks, Kaj   On Wed, 6 Mar 2024 at 22:21, Mayukh Bagchi <mayukh.bag...@queensu.ca> wrote: Hello Casperites, Hope you all are doing well. I have been working on an RFSoC-based backend for our BVEX (Balloon-borne VLBI Experiment) project. As a mobile K-band VLBI station we are using the RFSoC 4x2 for our IF stage for digitizing and storing the data. I have had a lot of help from the CASPER community in general in both setting up and troubleshooting the RFSoC so far.  Currently, I have deployed the spectrometer and a power meter which seem to be working fine. The next plan is to implement the 100 GbE and for that, I would first need to re-quantize the 14-bit data to 2 bits and then packetize it to VDIF standards to correlate with another ground station.  Any advice on a VDIF packetizer would be really helpful. I know the EHT uses a VIDF packetizer for the Roach 2s, Let me know if you have any questions.
