[802.3af] Gain in the DC/DC

[R karam <rkaram@xxxxxxxxx>]

Hi Yair

it seems like no vendor is willing to sign up for a freq F say the 77hz you picked
with zero tolerance, we are talking about integrating the oscillators...
so if we add 30% tolerance and say for lack of better data today we go to 100hz
now we are looking at 70-130hz range, what is the 'gain' of dc/dc converters in
this freq range?  what do we expect the 40-100mv at the input of the PD to
look like at the output of the converter where the audio is?

again, i am doing my homework, i mean work-work.

also Please note that what Dan brought up is important all testing must be with
cat-3 cables... NOT CAT-5.
