I'm building a switched-mode amplifier that needs a digital bitstream as input. It's a full bridge and - due to the specific switching scheme - needs multiple control signals (say 8 bits in total). The sigma-delta bitstream runs at frequencies up to 10MHz, so I need 10MB/s signals. Although the pattern could be generated in an MCU, it would really be a lot easier if I could use Matlab/Simulink/Python on a PC. So then I need a device with either a very large memory (say 100s * 10MB/s = 1GB), or send it in real-time to the amplifier. In our lab we have very nice equipment with large buffers, but I want something cheaper and more portable, so I'm aiming for streaming now.
Does anybody know a 'cheap' (< 1k€) device that can do this?
Searching online I seem to end up in 2 directions:
1) very expensive testing equipment
2) something like FT232H, which is nice, but I'm not sure it reaches the spec and frankly, I don't feel like the datasheet digging, programming, debugging, etc. I might have to - and will - do it eventually, but it would be great if something like this already existed.
Any help appreciated!
