plb_gemac SerDes mode on V4-FX?

Hi,

Can anyone confirm if the plb_gemac_v1_01_a in SerDes/MGT mode is supported on the V4-FX family?

The datasheet (DS460) and MPD file for the core state only V2-Pro, however XAPP809 updated October last year mentions both V2-Pro and V4-FX. The reference design with this XAPP is for V2-Pro on ML300 however.

V2-Pro MGTs used refclk, refclk2, brefclk and brefclk2, while V4-FX uses refclk1, refclk2 and grefclk. It seems unlikely that the gemac core would work with V4-FX without explicit support. The VHDL is encrypted so I can't just go in and look.

Thanks,

John
