FAQ

What is the maximum supported data rate per transceiver lane for XCKU040-2FBVA900E?

The XCKU040-2FBVA900E supports up to 16.3 Gb/s per transceiver lane using its GTH transceivers. This rate is guaranteed for production operation under industrial temperature conditions (-40°C to +100°C junction) with proper board-level signal integrity design, including controlled impedance traces and appropriate AC coupling capacitor placement. The XCKU040-2FBVA900E transceivers also support lower rates including 1.25 Gb/s (Ethernet), 3.125 Gb/s (PCIe Gen1), and 8.0 Gb/s (PCIe Gen2) with built-in protocol adaptors.

Does XCKU040-2FBVA900E support PCIe Gen4?

No, the XCKU040-2FBVA900E does not support PCIe Gen4. It integrates hardened PCIe Gen3 x16 Root Port and Endpoint blocks operating at 8 GT/s per lane. While the transceivers can be configured for custom protocols up to 16.3 Gb/s, they lack the Gen4-specific PHY features such as PAM4 encoding, FLIT-based transport, and enhanced equalization required for PCIe Gen4 compliance. For Gen4 support, AMD recommends the Versal ACAP or newer Kria KV260 derivatives. The XCKU040-2FBVA900E remains fully compliant with PCIe Gen3 specifications including ASPM L0s/L1 and AER reporting.

What is the recommended configuration mode for XCKU040-2FBVA900E in production systems?

The recommended configuration mode for XCKU040-2FBVA900E in production systems is Master SPI BPI (Quad-SPI) from a single 128-Mb or larger flash device. This mode provides fast (~120 ms) and reliable configuration with CRC checking, dual-boot capability, and in-system programmability. The XCKU040-2FBVA900E supports fallback to secondary image on CRC failure, and its dedicated configuration I/Os tolerate 1.8 V signaling compatible with common NOR flash devices. JTAG is reserved for debug and programming during development-not for production boot.

Can XCKU040-2FBVA900E interface directly with DDR4-2400 memory?

Yes, the XCKU040-2FBVA900E includes a hardened DDR4 memory controller supporting up to four 64-bit interfaces running at 2400 MT/s with full ECC, address/command parity, and programmable read/write leveling. It supports standard DDR4 components with 1.2 V VDD/VDDQ, 16–24 ohm ODT, and 16–20 ns tRCD/tRP. The controller is validated with Micron MT40A512M16 and Samsung K4A8G085WB-BCPB modules. The XCKU040-2FBVA900E's I/O banks are configurable for 1.2 V SSTL12, matching DDR4 signaling requirements without level shifters.

Is partial reconfiguration supported on XCKU040-2FBVA900E?

Yes, partial reconfiguration is fully supported on XCKU040-2FBVA900E using Vivado Design Suite 2020.2 or later. The device allows dynamic swapping of logical partitions (RLTs) while keeping the static region-including PCIe, memory controllers, and clocking-operational. Verified use cases include adaptive filter updates in wireless baseband and protocol stack switching in test equipment. The XCKU040-2FBVA900E requires bitstream encryption enabled and configuration security locked to prevent unauthorized partial bitstream injection.
