Honored ContributorADC acquisition with FPGA
Hi, I´m trying to interface an ADC9254 (from ti) converter in VHDL with board DSP Development Board for Stratix II Edition, in order to do an acquisition for signal, but i´m new in this type of de...

Honored ContributorHello,
there's no ADC9254 from TI. I presume you meant AD9254 from Analog Devices. VHDL wise, Interfacing the FPGA with the ADC is, in itself, quite trivial: use the ADC's Data Output Clock to register the ADC's Data Output signals. You'll also need to set some ADC parameters. IIRC, most of them can be set through configuration pin. In a worse case scenario, you'll need a small state machine to implement the SPI protocol.
