General Description
The Virtex™-5 family provides the newest most powerful features in the FPGA market. Using the second generation
ASMBL™ (Advanced Silicon Modular Block) column-based architecture, the Virtex-5 family contains four distinct platforms
(sub-families), the most choice offered by any FPGA family. Each platform contains a different ratio of features to address the
needs of a wide variety of advanced logic designs. This overview contains detailed information about the LX, LXT, and SXT
platforms. In addition to the most advanced, high-performance logic fabric, Virtex-5 FPGAs contain many hard-IP system
level blocks, including powerful 36-Kbit block RAM/FIFOs, second generation 25 x 18 DSP slices, SelectIO™ technology
with built-in digitally-controlled impedance, ChipSync™ source-synchronous interface blocks, system monitor functionality,
enhanced clock management tiles with integrated DCM (Digital Clock Managers) and phase-locked-loop (PLL) clock
generators, and advanced configuration options. The LXT and SXT devices also contain power-optimized high-speed serial
transceiver blocks for enhanced serial connectivity, a PCI Express™ compliant integrated Endpoint block, and tri-mode
Ethernet MACs (Media Access Controllers). These features allow advanced logic designers to build the highest levels of
performance and functionality into their FPGA-based systems. Built on a 65-nm state-of-the-art copper process technology,
Virtex-5 FPGAs are a programmable alternative to custom ASIC technology. Most advanced system designs require the
programmable strength of FPGAs. Virtex-5 FPGAs offer the best solution for addressing the needs of high-performance
logic designers, high-performance DSP designers, and high-performance embedded systems designers with
unprecedented logic, DSP, hard/soft microprocessor, and connectivity capabilities. The Virtex-5 LXT, SXT, and FXT
platforms include advanced high-speed serial connectivity and link/transaction layer capability.
