Total board thickness must be no greater than 62 mils (1575 µ).
Traces must be referenced to a plane on an adjacent PCB layer.
The reference plane must be either GND or the V
driver.
The reference layer must remain uninterrupted for its full length from device to
device.
All IOB output buffers must drive controlled impedance traces with characteristic
impedance of 50Ω ± 10%.
Total capacitive loading at the far end of the trace (input capacitance of receiving
device) must be no more than 10 pF.
