Specifications
The XC5VSX50T-2FFG1136C is a mid-range FPGA from the Virtex-5 SXT family (Xilinx, now AMD), built on the solid 65nm process and optimized for DSP-intensive applications that need a reliable set of high-speed serial transceivers without pushing into the largest device sizes.
Quick specs engineers usually check first:
- ~52,224 logic cells (with 4,080 CLBs/slices) — good capacity for multi-channel DSP filters, moderate video processing pipelines, FFT engines, or other signal-processing designs that need solid but not extreme scale
- 12 RocketIO GTX transceivers — these deliver dependable multi-gigabit serial performance, commonly up to ~6.5 Gbps in real-world links (strong choice for 10Gb Ethernet, PCIe Gen1/2, Serial RapidIO, or custom high-speed data interfaces)
- 480 user I/Os — plenty of flexible pins for external DDR2/3 memory controllers, fast ADCs/DACs, or board-level expansion
- Embedded block RAM around 4.86 Mbit (plus distributed RAM for smaller, low-latency buffers and FIFOs)
- ~288 DSP48E slices — second-gen 25×18 multipliers with 48-bit accumulators, tuned for high-throughput fixed- or floating-point math, FIR/IIR filters, transforms, and heavy arithmetic workloads
- Package: 1136-pin FFG (flip-chip BGA, ~35 × 35 mm), commercial temperature range (0°C to +85°C junction)
- -2 speed grade — offers excellent timing performance and good closure headroom while keeping power more manageable than the peak -3 bins in many DSP/SerDes use cases
The SXT platform is DSP + transceiver focused — it prioritizes those DSP48E blocks and GTX ports over embedded processors (no PowerPC; that’s FXT territory) or maximum plain logic density (more LX/LXT).
