This section provides the performance characteristics of some common functions and designs implemented in the Zynq UltraScale+ RFSoCs. These values are subject to the same guidelines as the AC Switching Characteristics section.
In each of the following LVDS performance tables, the I/O bank type is either high performance (HP) or high density (HD).
In LVDS component mode:
- For the input/output registers in HP I/O banks, the Vivado tools limit clock frequencies to 312.9 MHz for all speed grades.
- For IDDR in HP I/O banks, Vivado tools limit clock frequencies to 625.0 MHz for all speed grades.
- For ODDR in HP I/O banks, Vivado tools limit clock frequencies to 625.0 MHz for all speed grades.

The following table provides the maximum data rates for applicable memory standards using the Zynq UltraScale+ RFSoC memory PHY. Refer to Memory Solutions for the complete list of memory interface standards supported and detailed specifications. The final performance of the memory interface is determined through a complete design implemented in the Vivado Design Suite, following guidelines in the UltraScale Architecture PCB Design User Guide (UG583), electrical analysis, and characterization of the system.
