This section provides the performance characteristics
of some common functions and designs implemented in the Versal AI Edge devices. These values are subject to the same guidelines as the
AC Switching Characteristics section.
In each of the following performance tables, the I/O bank type is either
XPIO or HDIO.

- XPHY I/O is supported
through the Advanced I/O Wizard available with the Vivado Design Suite. The performance values assume a source-synchronous
interface. For asynchronous interfaces, see the
Advanced I/O Wizard LogiCORE IP Product Guide
(PG320).
- Package skews are not
included and should be removed through PCB routing.
- For multi-bank interfaces, the
performance is specified at 1066.5 Mb/s.
- For multi-bank interfaces, the
performance is specified at 533.25 Mb/s.
- SDR specifications are a subset of the
DDR specifications.

- The Versal device package pinout files specify XPIO
bank performance (XPIOperf). See ASCII package files information in the
Versal
Adaptive SoC Packaging and Pinouts Architecture Manual
(AM013).
- Dual in-line memory module (DIMM)
includes SODIMM and UDIMM.
- The QDRIV XP performance values are for
18-bit interfaces, for 36-bit interfaces the maximum performance is 933
MHz.
- The RLDRAM3 maximum performance with
burst length 2 (BL2) interfaces is 933 MHz in the -2L and -1L speed grades.
