RDA5815 Interesting all in one tuner IC.

Post by 2W0ODS » Sun Nov 25, 2018 7:52 am

This looks a very interesting all in one tuner on one IC, it can tune down to 250MHz and does not require a balun or much supporting hardware.

I think one of my satboxes has one of these so going to have a play around, certainly useful for Es'hail2 if I can get it to go sub 950MHz, but more interestingly is building something Minitioune compatible or similar.

I have recently had to write some code to control that chip and while the datasheet says it will go down to 250 MHz
the programmers guide and the register map I have don't show you how to program outside of the standard
950 MHz to 2.1 GHz range sadly.

P.S YesI know your original post was from almost 2 years ago (I am just a bit slow).

Hello Charles! You have the documentation for the RDA5815. I really need it. Could you share with me.

Hi Charles,
I am also looking for RDA5815 programming guide. If you still have it, would you mind sharing it with me too?
Thanks
