  1. chenshi started following High-Speed Pmod (ZYBO Z7-20 Board) and ZYBO Z7-20 Mechanical drawing (Physical dimension)

    The physical dimension of the mechanical drawing and the 3D model, which provided by Digilent do not match each other. I am wondering which one is correct. I would like to know the exact distance between 2 pmods.

    Hello guys, I am new here and I have a question related to the Zynq-7020 Development Board. I am planning to use the high-speed pmod to import a differential clock signal on the board. Currently, I am using package PIN U14 and U15, as they support SRCC. As the differential signals often have an impedance of 100 Ohm, the pmods are routed 80 Ohm differential according to the Zybo Z7 Board Reference Manual. I am wondering if it could cause reflection to the signals and how to avoid it. Thank you very much
