Software Defined Radio teardown: R820/RTL2832U Decap
Recently there has been much interest in two integrated circuit which were originally designed to receive FM radio and DVB-T TV (as used in Europe).
Some enterprising people quickly realised that since they were based on software-defined techniques they could be quickly re purposed for all sorts of clever things.
I bought one of Amazon and de-capped the two main ASICs inside.
The 1st one was the TV tuner from Rafael Micro, the R820
The 2nd is the COFDM demodulator from Realtek, the RTL2832U
