The original post simply mentioned EBU. Thus the confusion.
I think they mean SMPTE 12M LTC. VITC would also be possible, and not
completely without its merrits, but I doubt it.

I think it would count as stratum 1, since you are 1 hop
away from a master time source.

I might go for the Garmin one to start with, and see how it all works..
and then move up to a more reliable source of timing source in the
future...
When you say Reliable, what exactly do you all mean---
does it loose time?
Does it loose lock to the satellites?
because it's only millisecond

Yup.

Yup. That URL is for the LVC version. The PC version is the one powered
from a cigarette lighter. (Your first line above says PC when I assume you
mean LVC.)

Hi
The Thunderbolt has a GPS and an OCXO inside it. It's built in smarts align a
PPS created from the OCXO to the GPS PPS. This allows the PPS to be more stable
than a normal GPS PPS (less jitter). It also provides holdover on the PPS if
and when GPS sat's are not available.

For less money, you can get a Thunderbolt on the e-place. It will get you a lot

Thunderbolts show up regularly on eBay for $60 plus about $25 in shipping.
There are standard NTP drivers that appear to work ok with them.
