[time-nuts] Synchronisizing a 100MHz TCXO with Tbold, pse help

How good is the TCXO? Put another way - do you know what it's close in (1 to
100 Hz) phase noise looks like?
Even with a hardware loop, you normally can make it narrow enough that most
TCXO's are unlikely to be degraded by the TBolt. No matter how you do it,
below some cut off frequency the TCXO will have to follow the TBolt...

Subject: [time-nuts] Synchronisizing a 100MHz TCXO with Tbold, pse help
I like to synchronisize a fine 100MHz TCXO with the
10MHz output of the Tbold. The TCXO has a EFC input.
I know this can be done
using a PLL but I do not want to add noise
to the very good noise parameters of the TCXO
cause the 100MHz signal is to be used to clock
a FPGA which controlles fast cascaded ADCs.
Has anybody a circuit diagram to use?
Thank you in advance
