Note: For eye height position estimation in EMIF interfaces, refer to the PCB Design Guidelines (HSSI, EMIF, MIPI, True Differential, PDN) User Guide: Agilex™™ 5 FPGAs and SoCs. The eye mask estimation methodology defined in the PCB Design Guidelines (HSSI, EMIF, MIPI, True Differential, PDN) User Guide: Agilex™™ 5 FPGAs and SoCs takes precedence over specifications in HSIO Differential LVSTL I/O Standards Specifications table.
77 Percentage of P-leg and N-leg crossing relative to the midpoint of P-leg and N-leg signal swings.
78 Each sub-bank can only support a single voltage tolerance. The VCCIO_PIO tolerance can be extended to ±5% if the entire HSIO sub-bank is operating in any of the following modes. Else, you must supply the VCCIO_PIO voltage rail with a ±3% voltage supply tolerance.
  • PHYLITE mode
  • GPIO mode
