I find the MicroZed board has a USB3320 on it. And I find there is another newer USB3340 from Microchip. The major difference is USB3340 has built-in 1.8V regulator. Then we only need to route a 3.3V power rail to it. After more thinking, I find there may be some power sequence problem. Because FPAG may power on latter than the PHY chip. I have two questions now:
Any suggestion? Thanks.
