XC4VSX35-10FFG668C: Virtex-4 SX Optimized for Digital Signal Processing
The XC4VSX35-10FFG668C remains a cornerstone for high-performance DSP applications within the Xilinx Virtex-4 family. Specifically engineered for signal processing-intensive workloads, the SX sub-family provides a significantly higher ratio of DSP48 slices compared to the LX or FX variants.
Technical Breakdown & Core Specifications
The “SX” designation is the critical factor here. While the LX focuses on logic density, the SX35 is built for arithmetic heavy-lifting.
Logic Cells: 34,560
DSP48 Slices: 192 (The primary advantage for filter design and FFTs)
Block RAM: 3,456 Kb
Maximum User I/O: 448
Package: FFG668 (Fine-pitch Flip-Chip BGA, Lead-Free/RoHS compliant)
Speed Grade: -10
Temperature Grade: Commercial (0°C to 85°C)
Why Sourcing This Part Matters Now
In the current market, the XC4VSX35-10FFG668C is often utilized in Form, Fit, and Function (FFF) replacements for aging defense and telecommunications hardware. We understand that for these applications, “New/Clean” date codes and verifiable CoC (Certificate of Conformance) documentation are more important than price.
