Dear Altera, Please do not use Marvell components in your dev kits

I agree regarding the 88E1111. There's no reason to hold off on releasing that particular datasheet, but you'd have to take that up with Marvell. Altera's at the mercy of Marvell, or Broadcom or whomever they choose to go with and no, Altera doesn't have enough clout in this regard.

The reasons for not releasing the datasheets are legal...shouldn't be a surprise...and it's just the way it is.

Go look for PHY datasheets for Broadcom or Marvell. You'll find little available from their website. Broadcom, for instance, requires registration through something called "DocSafe" (NDA and Product Line Manager approval required) for most documents.
