I am resuming my university optical transceiver project privately. That was limited, because to quote Hal Abelson:"If I have not seen as far as others, it is because giants were sitting on my shoulders!"
Nobody on my back now. I can transmit over 500 metres over POF. I want to do it without all the crazy restrictions of that project year. I need suggestions for a fast small fpga but maybe could use a PAL or other device (This was forbidden me in Project time).
Specs are:
400~500 Mhz clock
Less than 8 inputs
One or 2 outputs (depending on config).
The device application is adjustable fast period measurement. Coding is minimal. No cpu exists.
Please suggest devices, or possible candidates.
I had looked at the Xilinx Artix 7 (fast, & with free linux friendly software) but they're huge behemoths, and i only need a small thing. Achronix in India are shipping 1.5Ghz devices(!) but the price & size rules them out.
