Specifications
The XC5VSX50T-2FFG1136I is a mid-range FPGA from the Virtex-5 SXT family (Xilinx, now AMD), built on the reliable 65nm process and tailored for DSP-heavy applications that need a decent set of high-speed serial transceivers without going overboard on size or cost.
Here’s the key stuff engineers usually check right away:
- ~52,224 logic cells (with 4,080 CLBs/slices) — good headroom for multi-channel DSP filters, moderate video processing pipelines, FFT engines, or other signal-processing designs that aren’t ultra-massive
- 12 RocketIO GTX transceivers — these deliver solid multi-gigabit serial performance, commonly supporting up to ~6.5 Gbps in real-world links (excellent for 10Gb Ethernet, PCIe Gen1/2, Serial RapidIO, or custom high-speed data streams)
- 480 user I/Os — plenty of flexible pins for external DDR2/3 memory, fast ADCs/DACs, or system interconnects
- Embedded block RAM around 4.86 Mbit (plus distributed RAM for smaller, quick-access buffers and FIFOs)
- ~288 DSP48E slices — second-gen 25×18 multipliers with 48-bit accumulators, optimized for high-throughput fixed- or floating-point math, FIR/IIR filters, transforms, and arithmetic-intensive tasks
- Package: 1136-pin FFG (flip-chip BGA, ~35 × 35 mm), industrial temperature range (-40°C to +100°C junction)
- -2 speed grade — gives you strong timing performance and good closure margins while balancing power better than the peak -3 in many DSP/SerDes scenarios
The SXT series focuses on DSP acceleration + fast transceivers — it prioritizes those DSP48E blocks and GTX ports over embedded processors (no PowerPC; that’s FXT land) or maximum plain logic density (more LX/LXT territory).
