Its Y-8F 600 version. Hopefully with western engines.
And as for communication system, JF-17s/FC-20s/Mirages/F-7PGs are equipped, being equipped and would be equipped with western communication system, european to be exact. And as per what i know, the ZDK-03 would also be having a western communication equipment, including data transfer equipment. Thus, all of these planes can communicate between each other, but my be due to US concerns & Swedish concerns, Erieye & F-16s are not directly linked with these assets, but then again, they may well connect them with each other, since whatever we are procuring from China, comes with western MIL-STD equipment and has western communication system, so if we can have the codes & system to link F-16s with Erieyes since they have western MIL-STD communication system, then we can link them with the Chinese planes which are coming with western MIL-STD & western communication system. I don't see a reason why can't we link them.
In the end, once again telling, all these assets would be connected with a ground control station, which will work as the command and control station for the whole battle theater, and they will communicate and give orders between the assets.
AESA is latest and much better.
