Re: [softrock40] Re: Raspberry PI stand alone SDR?
I can't find ANY complete spec data on the Broadcom chip ....not even the packaging and pinouts. Some even say that's the way they (Broadcom) want it. The only info is through the Rasberry Pi "next level assembly" and it's presently defined I/O appears to be limited for SDR use...... mainly dual high speed ADC/DAC capability, small color graphics display capability, DSP/MAC emphasis, etc. The intent is clearly an overall "PC" type of function which will be interesting in itself (low $$) but is outside this niche market (.....my 30 sec opinion). I give it the Rasberry.

It has a powerful GPU in it that could probably easily do the DSP required for 48 or 96kHz bandwidth. Unfortunately, that part of the Broadcom chip does not have open access to it. The OS does the access through a binary blob driver.

- In an article they explained that UK suppliers capable of making them in quantity could not meet their price point and those that could were unable to supply them in quantity.
However they've said that production in the UK in future may be an option.

Not quite as early as I promised, but hey, at least now I can go back to lurking without being called a tease, right?
