FAQ

What is the maximum supported data rate for GTY transceivers on the XCKU035-1FBVA900I?

The XCKU035-1FBVA900I supports GTY transceivers rated up to 16.3 Gb/s per lane. This enables compliance with 25G Ethernet, CPRI Option 7, and JESD204B/C standards. Actual achievable rates depend on PCB layout quality, reference clock stability, and signal integrity margins. The XCKU035-1FBVA900I datasheet specifies this as the guaranteed maximum under industrial temperature conditions.

Does the XCKU035-1FBVA900I support DDR4 memory interfaces?

Yes, the XCKU035-1FBVA900I integrates a hardened DDR4 memory controller supporting data rates up to 2,400 MT/s with ECC and AXI4 interface. It supports dual-rank, 64-bit wide configurations with programmable read/write leveling. The XCKU035-1FBVA900I documentation confirms compatibility with JEDEC-standard DDR4-2400 components and includes calibration sequences for reliable operation.

What is the operating temperature range for the XCKU035-1FBVA900I?

The XCKU035-1FBVA900I is rated for industrial temperature operation from –40°C to +100°C case temperature. This rating applies to the FBVA900 package variant and is validated per AMD's qualification testing. Thermal design must account for 28 W typical power dissipation, and derating curves are provided in the XCKU035-1FBVA900I thermal management guide.

Can the XCKU035-1FBVA900I be configured via Quad-SPI flash?

Yes, the XCKU035-1FBVA900I supports master Quad-SPI configuration mode using standard x4 SPI flash devices. Configuration bitstream loads directly into the FPGA upon power-up, with automatic CRC checking and fallback support. The XCKU035-1FBVA900I configuration user guide details timing requirements, pin assignments, and fail-safe recovery procedures.

Is partial reconfiguration supported on the XCKU035-1FBVA900I?

Yes, the XCKU035-1FBVA900I fully supports partial reconfiguration through Vivado Design Suite tools. This allows dynamic swapping of logic modules without resetting the entire device or interrupting active I/O or memory operations. The XCKU035-1FBVA900I implementation guide documents floorplanning constraints, checkpointing workflows, and runtime configuration port usage.
