I'm interested in whether it would be possible to use the ADALM-PLUTO time-of-arrival localization. This requires a very stable clock. I wonder whether it will be possible to feed in an external reference clock? In the revision-B schematics, it looks like there is no connector or jumper to switch from the built-in 40MHz oscillator to an external clock.
Also, if I do feed the clock from an external source (even if this involves removing the 40MHz oscillator), how difficult will it be to switch from 40MHz to 10Mhz? I see that the AD9363 does support 10MHz clocks, but will it is reasonably easy to configure the firmware for this clock frequency?
Thanks, Sivan Toledo, Tel-Aviv University
External clock for ADALM-PLUTO SDR
AD recommends/necessary steps are:
- remove TCXO 40.0 MHz and
- provide the external synchronisation via C123
It would be very helpful if AD could foresee on the PCB a Land Pattern for the installation of Ultra Miniature Coaxial Connector, UMCC, Part No. 128-0711-201 from Emerson Network Power (or install this connector):
Therefore, the external synchronisation can be easily provided via UMCC:

Thanks in advance.
