Afraid David M is right - the last PHY we used that did not require an NDA for access to the datasheet was the 1Gb National part on ROACH. It is unfortunate, but unavoidable at the moment. Hopefully the PHY will not need much discussion in terms of applications, so only people who need to get involved with the actual hardware design will need to sign NDA's.
