From the project
MISRC Is a multi channel RF capture device for FM RF, S-Video, CVBS RAW capture and anything else, but intended and supported for the decode family of projects vhs-decode, ld-decode, hifi-decode.
Hardware - Firmware - Software - Usage example
MISRC is a device to capture two signals at 12-bit and up to 40 MSPS (20 Mhz bandwith) (This could be extended to 80 MSPS in the future) and an additional 8-bit's (2-bit's for v2.5) of binary (auxiliary data) over USB 3.0.
It is intended to capture modulated tape deck RF for software demodulation, but also baseband CVBS/S-Video (Composite) video signals for software decoding, and can be used as a direct stream Oscilloscope but limited to 2vpp input voltage.
