    Regarding FX3 microSD Card Interface

    sunny.watts_3337731

      Hi,

       

      We are using USB FX3 controller CYUSB3035-BZXC in one our design.

       

      We are planning to use S-Port on FX3 controller for microSD card interface. As per the hardware guidelines document (http://www.cypress.com/file/139936/download),
      all the microSD interface signals should be length matched and the length should not exceed than 5 inches .


      In our layout, we kept the length of all these signals between 4.22 – 4.25 inches. Please let us know if we shall keep the length of all these signals same with tolerance of +/-0.030 inches. Please let us know if the clock signal should also be kept of same length or not?

       

      Thanks & Regards,

      Sunny Watts
