I am planning to user FPGA GPIO to control data loading, Does it require SPI or Can I directly interface?
FPGA IO does comes with SPI bus.
Can you suggest some hardware SPI.
You need to implement a hardware SPI into your FPGA to interface with the AD9835.
That being said, Im not sure what do you mean by directly interface.
I didn't know that FPGA comes now with dedicated SPI blocks...
The SPI is only the communication protocol, still not fully understand your question, sorry.
Do you refer to electrical specification?
FPGA's does comes with SPI Logic levels not the Hardware, One need to write HDL logic or use IP.
I got the solution. Thanks.
