Hi, I'm using UG293(AD9613) with HSC-ADC-EVALCZ board.


I'm have a question with fpga coding about spi controlling.


I thought SPI signals go USB chip to FPGA and then goes to ADC. But when I was looking at fpga code in ftp site(ad9643) the output of csb was not in there.


1. The question is does SPI signals goes directly USB chip to ADC?


2. Second question is there a way to control spi signals with fpga?


3. Can I get a documentation with this kind of things? I read AN 877 and AN 878, but I couldn't understand about this.
