    GPIO synchronized output


      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.
