Will it do 100 meters or more, in bad neighborhoods?
I'm not the right person to ask but since it is expected to maintain
between 2.5 and 100 nanosecond sync with CPE nodes (cable modems) I assume
it requires RF techniques not readily available (or cost effective) outside
a cable plant.
The DOCSIS time interface is "fun" in that it uses two different
frequencies to provide the transfer, so you get an interpolation
function from relatively benign frequencies. Will make your crystal
supplier happy.
Cheers,
Magnus
