Hi,
I'm designing with the Gowin FPGA and they have used this B50610C1KMLG from broadcom as the Ethernet PHY,Gowin has published the schematics for their eval board, But the problem with this part is that there is no datasheet for it, the question is where can I get the datasheet? is there a chinese or russian site containing the Data sheet, Also if there is an altium lib for this part, it would be nice too.
