XC4VSX35-10FFG668I Xilinx Virtex-4 SX FPGA – Industrial Grade DSP Processing Device
The XC4VSX35-10FFG668I is a DSP-oriented FPGA from the Xilinx Virtex-4 SX family, designed for applications that require stable real-time signal processing and operation across extended temperature ranges.
Unlike general-purpose logic-focused devices, the Virtex-4 SX series is optimized around DSP48 slices, making this part especially suitable for filtering, modulation, FFT acceleration, and other compute-heavy data path workloads. The industrial temperature rating and compact FFG668 package make it a practical choice for embedded and industrial platforms with limited board space.
