78 This specification is limited by the I/O maximum frequency. The maximum achievable I/O frequency is different for each I/O standard and is dependent on design and system specific factors. Ensure proper timing closure in your design and perform HSPICE/IBIS simulations based on your specific design and system setup to determine the maximum achievable frequency in your system.
