11 years agoRF filter with FPGA / CPLD
Hello to all. first of all I hope not wrong section of this forum. I studied electronics, I know very well for C ++ and assembly MCU. in recent times I have found out what are the FPGA and CPL...

11 years agomany thanks for the quick response
I have thought of using FPGA to create a low pass filter or high-pass that can be programmed externally by MCU. I thought about using this http://www.ebay.it/itm/altera-fpga-cpld-programmer-usb-blaster-compatible-lc-maxii-epm240-dev-board-/141315924702?var=&hash=item20e715e2de"]http://www.ebay.it/itm/altera-fpga-cpld-programmer-usb-blaster-compatible-lc-maxii-epm240-dev-board-/141315924702?var=&hash=item20e715e2de%22]http://www.ebay.it/itm/altera-fpga-cpld-programmer-usb-blaster-compatible-lc-maxii-epm240-dev-board-/141315924702?var=&hash=item20e715e2de (http://www.ebay.it/itm/altera-fpga-cpld-programmer-usb-blaster-compatible-lc-maxii-epm240-dev-board-/141315924702?var=&hash=item20e715e) like you said, there are models that reach 200/400mhz but that of the link on the PCB has a crystal from 50mhz I wonder if the speed of the quartz corresponds to that of the sampling rate or the integrated circuit has another internal clock faster? last question : the fpga they process only digital pins? I have to add an external ADC?
