FAQ

What is the maximum supported DDR4 data rate for the XCKU040-2FBVA676E?

The XCKU040-2FBVA676E supports DDR4 memory interfaces up to 2400 MT/s with two independent 72-bit interfaces (64-bit data + 8-bit ECC). This capability is implemented via hardened memory controller IP and verified across industrial temperature range with JEDEC-compliant timing margins. The XCKU040-2FBVA676E achieves this performance using calibrated read/write leveling and on-die termination control.

Does the XCKU040-2FBVA676E include built-in PCIe Gen3 support?

Yes, the XCKU040-2FBVA676E integrates a hardened PCIe Gen3 x16 endpoint block compliant with PCI Express Base Specification 3.0. It supports both root port and endpoint configurations, includes AXI4 streaming interfaces, and delivers <100 ns transaction latency. The XCKU040-2FBVA676E requires no external PHY and meets PCIe electrical compliance when used with reference clock and layout guidelines.

What is the operating temperature range specified for the XCKU040-2FBVA676E?

The XCKU040-2FBVA676E is rated for industrial temperature operation from -40°C to +100°C case temperature. This rating applies to the FBVA676 package variant and is validated per JEDEC JESD22-A104 stress testing. The XCKU040-2FBVA676E maintains full functionality-including all GTY transceivers and memory controllers-across this range without derating.

How many GTY transceivers does the XCKU040-2FBVA676E provide?

The XCKU040-2FBVA676E includes 24 GTY transceivers, each capable of line rates from 10.3125 Gb/s to 16.3 Gb/s. These transceivers support protocols including 10/25G Ethernet, CPRI, and PCIe Gen3. The XCKU040-2FBVA676E allocates them across four quads, with dedicated reference clock inputs and shared PLLs per quad.

Is partial reconfiguration supported on the XCKU040-2FBVA676E?
