Specifications
The XC5VSX50T-1FF1136C is a mid-range FPGA from the Virtex-5 SXT family (Xilinx, now AMD), built on the dependable 65nm process and designed for applications that lean into DSP processing with a reliable set of high-speed serial transceivers.
Here’s the key info engineers usually check first:
- ~52,224 logic cells (with 4,080 CLBs/slices) — gives you decent headroom for multi-channel DSP filters, moderate video pipelines, FFT cores, or other signal-processing designs that need good but not extreme scale
- 12 RocketIO GTX transceivers — these handle multi-gigabit serial links solidly, typically up to ~6.5 Gbps in real-world use (great for 10Gb Ethernet, PCIe Gen1/2, Serial RapidIO, or custom high-speed data streams)
- 480 user I/Os — solid flexible pin count for external DDR2/3 memory, fast ADCs/DACs, or board interconnects
- Embedded block RAM around 4.86 Mbit (plus distributed RAM for quick smaller 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 arithmetic-heavy tasks
- Package: 1136-pin FF (flip-chip BGA, ~35 × 35 mm), commercial temperature range (0°C to +85°C junction)
- -1 speed grade — balances performance, timing closure, and power draw nicely for many DSP/SerDes-focused apps
The SXT series is DSP + transceiver centric — it emphasizes those DSP48E blocks and GTX ports over embedded processors (no PowerPC; that’s FXT territory) or maximum plain logic density (more LX/LXT).
