FAQ

What is the maximum transceiver line rate supported by the XCVU125-2FLVB2104E?

The XCVU125-2FLVB2104E supports GTY transceivers with a maximum line rate of 28.1 Gbps per lane. This enables compliance with PCIe Gen3, 25G Ethernet, and JESD204B v2.0 standards. The transceiver architecture includes built-in PRBS pattern generation and error detection for link integrity verification. All 96 GTY channels on the XCVU125-2FLVB2104E are rated for this speed grade under industrial temperature conditions.

Does the XCVU125-2FLVB2104E support partial reconfiguration?

Yes, the XCVU125-2FLVB2104E fully supports dynamic partial reconfiguration (PR). This allows selective logic modules to be updated at runtime without resetting the entire device or disrupting active functions. PR is implemented using frame-based bitstream loading over ICAP and is validated for use in mission-critical systems such as airborne radar where continuous operation is mandatory. The XCVU125-2FLVB2104E includes dedicated configuration logic to ensure atomicity and CRC protection during partial bitstream writes.

What configuration security features are integrated into the XCVU125-2FLVB2104E?

The XCVU125-2FLVB2104E integrates AES-256 bitstream encryption and HMAC-based authentication to prevent unauthorized access and cloning. Bitstream decryption occurs on-die using a unique device key fused during manufacturing. Configuration integrity is verified before execution, and tampering triggers automatic device lockdown. These security mechanisms are enabled by default in production-grade XCVU125-2FLVB2104E devices and meet DO-326A/ED-202A assurance requirements for avionics applications.

Which memory interface standards does the XCVU125-2FLVB2104E support?

The XCVU125-2FLVB2104E supports DDR4, LPDDR4, and RLDRAM3 memory interfaces with hardened controller IP. It delivers up to 128-bit wide DDR4 interfaces running at 2400 MT/s, with on-die termination and write-leveling calibration. Memory controllers are integrated into the UltraScale architecture and do not consume logic resources. The XCVU125-2FLVB2104E also provides native support for ECC and address/command parity checking across all supported memory types.

Is the XCVU125-2FLVB2104E pin-compatible with other Virtex UltraScale devices in the FLVB2104 package?

Yes, the XCVU125-2FLVB2104E shares the same 2104-ball FCBGA package and pinout with other Virtex UltraScale devices in the FLVB2104 footprint, including XCVU9P-2FLVB2104E and XCVU13P-2FLVB2104I. Power, configuration, and I/O bank assignments are identical across these variants. This enables hardware reuse and migration paths within the same PCB layout. The XCVU125-2FLVB2104E maintains full mechanical and thermal compatibility with those parts, simplifying qualification for multi-tier product families.
