FAQ

What is the core voltage requirement for the XCKU5P-L2FFVB676E?

The XCKU5P-L2FFVB676E requires a tightly regulated 0.85 V ±3% core supply (VCCINT) delivered to its dedicated power rails. This voltage powers the programmable logic fabric, CLBs, and interconnect resources. Deviation beyond tolerance risks timing violations or functional failure. The XCKU5P-L2FFVB676E datasheet specifies strict transient response and ripple limits to ensure reliable operation under dynamic logic switching loads.

Does the XCKU5P-L2FFVB676E support PCIe Gen4 x16 in endpoint mode?

Yes, the XCKU5P-L2FFVB676E includes a hardened PCIe Gen4 x16 endpoint block compliant with PCI Express Base Specification Revision 4.0. It supports all standard transaction types, MSI/MSI-X interrupt delivery, and ASPM L0s/L1 power states. The XCKU5P-L2FFVB676E can operate as either root port or endpoint without external PHY, enabling direct attachment to host CPUs or downstream devices in accelerator cards.

How many GTY transceivers does the XCKU5P-L2FFVB676E have, and what is their maximum line rate?

The XCKU5P-L2FFVB676E integrates 24 GTY transceivers, each capable of NRZ operation up to 32.75 Gb/s and PAM4 operation up to 58 Gb/s. These transceivers support protocols including 100G Ethernet, CPRI/eCPRI, and proprietary high-speed serial links. The XCKU5P-L2FFVB676E's GTY lanes are distributed across eight quads, with independent reference clock inputs per quad for flexible board-level routing.

Is the XCKU5P-L2FFVB676E pin-compatible with other Kintex UltraScale+ devices in the same package?

No, the XCKU5P-L2FFVB676E is not pin-compatible with other Kintex UltraScale+ devices in the FFVB676 package. While physical ball count and footprint match, I/O bank assignments, transceiver locations, and power rail allocations differ across speed grades and density variants. Migration between XCKU3P-L2FFVB676E and XCKU5P-L2FFVB676E requires PCB redesign due to incompatible pin functions and voltage domain mapping.

What configuration modes does the XCKU5P-L2FFVB676E support?

The XCKU5P-L2FFVB676E supports JTAG, Master SelectMAP, Slave SelectMAP, and Quad-SPI configuration modes. JTAG is used for boundary scan and debug; SelectMAP enables high-speed parallel loading via microcontroller or processor; Quad-SPI allows boot from serial flash with fast read speeds. The XCKU5P-L2FFVB676E also supports secure fallback configuration and dual-bitstream redundancy for mission-critical deployments.
