11/5/2002 - Altera introduced the Stratix GX device family, a fusion of the industry's fastest FPGA architecture with high-performance 3.125-Gbps transceiver technology. Building further on the concept of integrated transceivers first introduced to the market by Altera with the Mercury device family, Stratix GX devices are based on the powerful Stratix device architecture and include customer-defined features for high-speed design implementation. Stratix GX devices offer a more robust set of transceiver features implemented as hard intellectual property (IP) than any other FPGA product. As a result, this second-generation transceiver technology delivers a low-risk path to designers building multi-gigabit applications in the mass storage system, high-end broadcast, electronic, and communications markets.
"With devices ranging from four to 20 high speed serial channels at speeds up to 3.125 Gbps and very low power consumption per channel, the Stratix GX family fits the bill in scaling up to a full, high-speed chassis or scaling down to the minimum requirement for a single line card," said Jeff Rhodes, business manager at Motorola Computer Group. "The flexibility of Altera's Mercury devices enabled us to implement our first generation Multi-Service Packet Transport Platform (MXP) in parallel with the emerging PICMG 2.20 switch fabric standard."
"The economics of 0.13-micron silicon are changing system architecture at a fundamental level, and the role of programmable technologies is becoming increasingly important as designers look for solutions that meet their requirements without painting them into a technological corner," said Jeremey Donovan, vice president and chief analyst with Gartner Dataquest's semiconductor group. "The melding of high-speed transceivers and programmable technology in particular is a logical outcome of the industry's new economic factors."
Low-Risk Path to Multi-Gigabit Design
Designed with up to 20 full-duplex transceiver channels, the Stratix GX family is well equipped to handle high throughput datapaths. This includes high-speed backplane and chip-to-chip communication technologies that are rapidly emerging in high-speed, data-intensive applications. Combining Stratix GX devices with the powerful Quartus® II design software and available IP cores optimized for transceiver applications gives system architects the power to get high-speed systems up and running in minimal time. More than just a robust transceiver on an FPGA, Stratix GX is a complete design platform that includes Gigabit Ethernet XAUI or SONET/SDH IP cores, models for system verification, and board layout guidelines. These are critical elements that designers need to create a working transceiver-based system for backplane or chip-to-chip applications.
As with the Stratix and Cyclone FPGA families, Altera once again brought customers from a wide array of markets into the product definition process. Faced with a common challenge-the need for reliable, high-speed data transfer across all design segments-Altera designed Stratix GX devices to include features specifically identified by customers as critical for successful design implementation.
Tuned for backplane applications
Stratix GX devices provide the rich features required for success in backplane applications. Stratix GX devices provide both 40-inch FR4 drive capability and receiver equalization. Devices also include hot-socketing capability.
Low transceiver power consumption
At 175mW per channel and only 450mW per gigabit transceiver block, Stratix GX transceivers consume less than half the power of competing FPGA solutions. In addition, Stratix GX devices support independent power down of either the transmit or receive channels. Low power consumption increases reliability and reduces cost.
Support for a high-speed protocols such as XAUI and SONET/SDH
The Stratix GX architecture is the only FPGA and multi-gigabit solution in the industry that includes dedicated circuitry for backplane applications in both XAUI and SONET/SDH systems. XAUI-specific features include dedicated rate-matching, word-aligning, and clock-management circuitry. Devices include dedicated silicon to perform SONET/SDH pattern detection and SONET/SDH pattern transmission, and to support both an 8- and 16-bit wide data bus without the 8B/10B encoder/decoder. The dedicated circuitry increases reliability and provides time-to-market and cost advantages.
Hard DPA for source synchronous I/O pins
The industry's only embedded silicon implementation of dynamic phase alignment (DPA) circuitry provides a high-speed complement to the transceiver bandwidth. DPA simplifies high-speed board design and layout through the automatic elimination of skew introduced by unmatched trace lengths, jitter, and other skew-inducing effects. Hard DPA (vs. soft DPA) specifically provides better immunity to temperature or voltage variation and much lower power consumption.
The right logic densities for the transceiver channel count
For high transceiver channel count applications, the Stratix GX architecture provides a more optimized channel-to-logic ratio than alternative solutions. Stratix GX devices provide reduced logic options due to the significant use of dedicated silicon to address both transceiver and source-synchronous applications.
"As the only second-generation product in the market, we're well ahead of our competitors. Stratix GX FPGAs have the advantage of including Altera's experience of having worked with customers implementing multi-gigabit transceivers into their designs," said Tim Colleran, vice president of product marketing at Altera. "Our intention is to pass on this experience as a competitive advantage to our customers building high-speed applications, allowing them to get their products to market faster and with less risk."
A beta version of Quartus II version 2.1 with support for Stratix GX has been shipping to customers since June of this year. A design kit specifically targeted for Stratix GX is now available through local Altera representatives as a complement to the Quartus II version 2.1 software. Quartus II version 2.1 provides support for system-level design with advanced features and tools such as LogicLock, SOPC Builder, DSP Builder, board-level timing analysis tools, and signal integrity analysis tools. Quartus II provides the ideal development tool for meeting the design challenges of multi-million gate designs. It supports major operating systems such as Windows XP, Windows NT, Windows 98, Windows 2000, Sun Solaris, HP-UX, and Linux operating system.
Packaging, Pricing, and Availability
Stratix GX devices will be available in the 672-pin and 1,020-pin FineLine BGA® packages. The first device, the EP1SGX25D in the 1,020-pin FineLine BGA package will begin shipping in Q1 2003. Devices in the family will be as low as $99 in 50,000 unit volumes by mid-2004.
