High speed (1GSPS) Analog signal processing with Jetson

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier

Hi,

I’m considering an application where I’ll need to process analog signal sampled at ~1GSPS@12bit for processing on the GPU. There seems to be quite few PCIe based sampling cards in the market that in theory could be connected to Jetson, but I’m concerned whether such application exceeds the platform I/O capabilities.

Does anyone has experience with applications that uses such RF ADC converters and these levels of I/O bandwidth? Any pitfalls I should be aware of?

Thanks,
Jacky

Have some discussion on here.

@ShaneCCC, Thanks for the pointer.
However, the thread is rather old (2015) and AFAIU talks about older tegra platforms where the latest Xavier has 8x PCIE Gen 4 which should be able to support up to 15.7 GB/s.

Thanks,
Jacky
