do you know if there's a MY card that offers aes50?
Not at present. Yamaha currently make interfaces for Ethersound and Cobranet systems, but not AES-50. They might in the future, but I'm not aware of anything in the pipeline at the moment.

Although they have some using cat5 I'm guessing it has to be that specific protocol, is that correct?
Yes, AES-50 (also called SuperMac) is a layer-1 protocol that employs standard Ethernet cabling and connectors but operates under bespoke ‘media access control’ protocols which aren’t compatible with mainstream Ethernet or IP systems at all.
Ethersound and Cobranet are layer2 (data-link) protocols which wrap the digital audio data into standard data packets and can therefore operate within standard Ethernet networks – although some systems may still require dedicated audio-only networks to guarantee stable latencies and data capacities. Other (non-inter-compatible) Layer 2 systems include the AES-51 format, Allen & Heath’s ACE, Calrec’s Hydra system and Roland’s REAC format.
Full ‘Network’ or ‘Layer 3’ systems fully embrace the IP standard and are completely compatible with all standard networking systems (although most cannot be used over the Internet). The Institute of Electrical and Electronics Engineers (IEEE) is working on international standards for the transport of audio and video over Ethernet within the layer 3 protocol under the ‘AVB’ group, and presumably this will eventually become the ‘industry standard’ format. Current Layer 3 systems include ALC NetworX’s Ravenna, Audinate’s Dante, QSC Audio’s Q-LAN, and Telos Axia’s LiveWire... But for a future-proof system, AVB is probably the format to look out for.

My other thought was this company
I don't have any experience of that system but it appears to be a Layer 1 protocol design. Latency figures are very good.
