Or remove the OCXO from the Thunderbolt and feed the GPS receiver with the FE5680 10MHz. Either modify the FE5680 for EFC och program a uC to get time/freq error from the receiver (bytes 6 to 9 in message 0x8F-A7). Then close the loop by adjusting 5680 frequency through RS232 from the same uC. Depending on use, you can retain the good Tbolt ocxo and lock it with a PLL to the 5680 10MHz. -- Björn _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
