To improve the SSO noise margin, follow these recommendations.
  • Reduce the number of toggling outputs in the I/O bank. You can distribute the outputs to other I/O banks with better SSO noise margin.
  • Reduce the drive strength and slew rate of the outputs.
  • Consider adding an on-board series resistor at the receiver side. Altera recommends that you perform IBIS or SPICE simulations to determine the suitable series resistor value for your specific application.
