FAQ

What is the maximum supported I/O standard voltage for XC5VLX50-1FFG676CES?

XC5VLX50-1FFG676CES supports I/O bank voltages from 1.2 V to 3.3 V, enabling direct interfacing with DDR2, QDR SRAM, and legacy parallel buses. Each of the 12 I/O banks operates independently, allowing mixed-voltage operation across the device. This capability is confirmed in Xilinx DS100 and UG191 documentation for the Virtex-5 LX family.

Does XC5VLX50-1FFG676CES include built-in PCI Express functionality?

Yes, XC5VLX50-1FFG676CES integrates hard-wired PCI Express v1.1 Endpoint blocks, including MAC layer, transaction layer packet handling, and AXI4 streaming interface. It does not require soft-core implementation, reducing latency and resource usage. This feature is documented in Xilinx UG194 and verified in production radar gateway designs using XC5VLX50-1FFG676CES.

What is the industrial temperature range qualification for XC5VLX50-1FFG676CES?

XC5VLX50-1FFG676CES is qualified for operation from -40°C to +100°C ambient temperature, meeting industrial-grade reliability requirements. The "E" suffix in the part number denotes extended temperature range, validated per Xilinx specification XTP052. This rating supports deployment in avionics and outdoor radar enclosures without forced cooling.

How many 2.5 Gbps transceivers does XC5VLX50-1FFG676CES contain?

XC5VLX50-1FFG676CES contains 12 GTP transceivers, each capable of 2.5 Gbps line rates. These support protocols including SATA I/II, Serial RapidIO 1.x, and custom high-speed links. Transceiver placement and power sequencing are detailed in Xilinx UG192, and all 12 are accessible in the FFG676 package.

Is XC5VLX50-1FFG676CES pin-compatible with other Virtex-5 LX devices in FFG676 packaging?

XC5VLX50-1FFG676CES shares the same FFG676 footprint with XC5VLX30-1FFG676C and XC5VLX110-1FFG676C, but I/O bank assignments and configuration pin locations differ. While mechanical mounting is identical, signal routing and power delivery must be verified per device-specific pinout files (e.g., Xilinx XDC constraints). No guaranteed pin-to-pin compatibility exists across LX variants.
