Hi
The super stable means easily 1ppm which means about one second every 16 days.
Get a look to www.matel-fordahl.fr or www.kvg-gmbh.de . However my PCB can be
implemented with classics DIL14 pins 1 7 8 14 footprints for people who has
very bad computer clock or simply wants to put the clock outside the hot
computer box or even outside the hot computer room.
My goal is to keep internal machines on time to each other more than to keep an
absolute clock. The internal ntp is enough for that as networks are 100M or 1
giga. The PPS is used only to MY stratum 0 (my PCB has 2 outputs as the max232
has 2 but I am using only one for the ntpd).
The orphan mode is never used as long as a source is available. The 127.127.1.0
IS always available, it is this one that I need to get rid after the
initialization.
The problem is here: I need the local for initialization. But the local later
on makes a conflict because it is a bad source.
The time1 and time2 would have been the solution to adjust the phase on startup
but I don't want to do that on each power up. I can do that if I would be able
to use back quotes to call a script.
Cheers
I'd suggest not trying to use PPS but derive the system clocks
from your ocxo.
Otherwise you have a problem to synchronize the PPS to one of
your systems.
