    FX3 VIO1 voltage selection for the CYUSB301X family

    user_370633663

      I need some help selecting the optimum voltage for VIO1. In particular, I am interested in anyone's real-life experience of using different voltages (1.8, 2.5, and 3.3 volts) at different frequencies. For example, if the FX3 is operated at 100 MHz, can the I/Os be truly driven at 3.3 volts?, Or do I need to go for 1.8 volts to minimize noise?

       

      What would be (really) nice to have  is a table that shows the maximum frequency that can be reliably achieved at each voltage.

       

      Thanks,
