Is it possible to access the analog interface of the LMS7002 on the LimeSDR??? (To transmit/receive a PAL/NTSC video signal)
You can find the schematics here:
If you look at the datasheet for the LMS7002M, to find out the analogue pin names https://wiki.myriadrf.org/LimeMicro:LMS7002M_Datasheet#Package_outline_and_pin_description
And then cross reference those names to the page 4 of the schematic (IC1C - “Baseband external IO”), it is reasonably clear that none of them are used.
And you can verify that by looking at all the pin headers, which are only on the digital side of the board, none of them are for analogue interfaces.
