Hi,
I have a question on this article:
Drive Multiple GPIO Pins Simultaneously in FX3™ - KBA212557
I need to produce 2 simultaneously output (somehow SPI in high freq) : CLK up to 28.8MHz and MOSI which should be synchronized with an input clock to FX3
I am wondering that if I use from the mentioned article, Can I get this frequency on gpio?
As in Increasing Frequency of Bit-Banged GPIO Clock in EZ-USB® FX3™ - KBA90267 , there is a limitation for frequency range.
If no, how can i get these signals from Fx3 without using GPIF II? I have only 3 pins free on FPGA and no more for using GPIF II.
Thanks

Hi,
Now, I used another way to get the desired results:Synchronized serial IN interface in GPIF .
I wanted to send a clock and get data, frame sync(SOF) and clock at the same time as output which are synchronized with the input clock. so now i had to split that input clock and use it as output as well.
Thanks
