• High-Speed Transceivers (Stratix GX family)  Family transceivers support 500 Mbps to 3.1875 Gbps with clock-data recovery (CDR) and embedded SERDES; devices in the family are available with 4–20 channels and support multiple serial protocols.
• Protocol and Signal Integrity Features  Family-level support for protocols such as XAUI, Gigabit Ethernet, SONET/SDH, PCI Express, Fibre Channel, and Serial RapidIO, plus programmable VOD, pre-emphasis, and equalization for improved signal integrity.
• I/O Count & Standards  455 I/O pins and support for LVDS, LVPECL, and 3.3-V PCML on reference clocks and receiver inputs as specified for the series.
• DSP & Clocking Resources  Includes high-speed DSP blocks for multiply-accumulate functions and up to eight general-purpose phase-locked loops for advanced clock management (series feature).
• Package & Mounting  Surface-mount 672-BBGA package (672-FBGA, 27×27) suitable for compact board layouts.
• Electrical & Environmental  Core voltage supply range 1.425 V to 1.575 V; industrial operating temperature range −40 °C to 100 °C; RoHS compliant.

Typical Applications

• High-speed backplane interfaces  Leverages multi-gigabit transceivers and abundant logic to implement protocol bridging and packet-handling functions on high-bandwidth backplanes.
• Chip-to-chip connectivity  Embedded SERDES and CDR support reliable, low-latency serial links between devices in multi-chip systems.
• Communications protocol bridging  Useful for implementing protocol conversion and aggregation for standards such as XAUI, GigE, SONET/SDH, PCI Express, and Fibre Channel.
• High-performance data buffering and processing  On-chip RAM and DSP blocks enable real-time buffering, packet processing, and signal processing tasks.

Unique Advantages

• Substantial logic capacity: 25,660 logic elements provide ample resources for complex control, protocol stacks, and custom accelerators without immediate need for external logic.
• Significant on-chip memory: Approximately 1.94 Mbits of embedded RAM reduces dependence on external memory for intermediate buffering and FIFOs.
• High serial bandwidth capability: Stratix GX series transceivers operate up to 3.1875 Gbps per channel, enabling multi-gigabit full-duplex links for high-throughput designs.
• Flexible I/O and signal conditioning: 455 I/Os plus programmable VOD, pre-emphasis, and equalization allow adaptation to a wide range of interface requirements and channel conditions.
• Industrial temperature range: Rated from −40 °C to 100 °C for deployment in systems that require extended temperature tolerance.
• Compact BGA packaging: 672-BBGA (27×27) delivers dense I/O in a space-efficient footprint for board-level integration.
