RE: Specifying Discovery
I'm glad we are all on the same page here. Our standard can only supply
parametrics, not implementations. We simply must make sure that we do a
careful job in specifying those parameters.

Representing the IC vendor community, I couldn't agree more. Each vendor
bring specific expertise and specific process capabilities to the Discovery
task. Therefore innovation and competition are encouraged by defining
criteria, and leaving methodology to the implementer.

I agree.... The parameters of the loop belong in the Standard, the
way you measure them is implementation (not in the Standard).

I'm sure others have already thought of this, but having a dialog
might help us get to completion sooner, so here goes.
Now that there is a discovery method on the table I began thinking
about how we specify it. Seems to me we only need to specify the identity
network on the PD end, some sort of simple limitations on the PSE discovery
signals, and then put an annex in the standard showing a proven
implementation. The actual method used to do discovery in the PSE should be
left to the individual implementor. Things like radiated and conducted
noise, noise susceptibility, ESD susceptibility, etc. need not be in the
spec., but an annex might point out the relevant documents governing them.
I'm sure I've missed a few things here, but seems to me the actual spec.
part is pretty short. Comments??
