Re: I need to interface a PIC32 micro to 1000BASE-SX SFP module
Its an option, but there are risks changing the micro core:
* It's a very noisy environment - short circuit test of this 60KV PSU may cause a crash. Clocks can run slower, but the core voltage is lower. (Only recently moved from 5V PICs and that took some convincing internally!)
* Much of the code is presently tied to the internal micro peripheral set. input capture/timer counter hardware blocks. Porting that is going to be painful. I guess as always, looking for the easy modification to the existing 100BASE-FX ethernet design. If I was starting the design from scratch, well...
