    NORWOOD, Mass.--(BUSINESS WIRE)--Jan. 20, 2005--

    - Accompanying reference design meets industry's MSA specifications, enabling high-performance, cost-effective optical module solutions.

    Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications, today announced the availability of a SFP (small form factor pluggable) optical transceiver chipset and reference design that supports both gigabit Ethernet and Fibre Channel data rates up to 4.25 Gbps (gigabits per second) in SAN (storage area network) equipment. According to market research firm IDC (International Data Corporation), Fibre Channel switch port shipments are expected to grow annually by an average of 40 percent through 2008. Optical transceivers that connect to Fibre Channel switches at 4.25 Gbps will be key components in this market, enabling developers of SAN equipment to double the existing data rate, while remaining compatible with older modules running at 1 Gbps and 2 Gbps data rates.
    "Analog Devices' 4x Fibre Channel transceiver chipset and reference design offers optical transceiver designers a turnkey solution with best-in-class performance for power, sensitivity and eye quality," said Peter Real, product line director for Analog Devices' High-Speed Networking Group." By making both the SFP Fibre Channel chipset and reference design available at the same time, Analog Devices is enabling optical transceiver manufacturers to reduce the time it takes to bring their SAN products to market."

    About the 1x/2x/4x Fibre Channel SFP Chipset

    The high-performance 1x/2x/4x SFP chipset meets the requirements of the Fibre Channel MSA (Multisource Agreement) specifications and is optimized for SFF-8472 digital diagnostics. The existence of an MSA standardizes modules, offering the market significant time and cost savings over custom modules. The SFP chipset includes four Analog Devices' products designed to work seamlessly together:

--	On the receive chain, the ADN2882, a 4.25 Gbps TIA (transimpedance amplifier), has a sensitivity of -22 dBm, while dissipating only 75 mW of power.
--	The ADN2892, a 4.25 Gbps limiting amplifier, features selectable bandwidth for operation at the 1x and 2x Fibre Channel rates (1.063 Gbps and 2.125 Gbps) and the gigabit Ethernet rate (1.25 Gbps) ensuring backwards compatibility to 1x and 2x Fibre Channel modules, while dissipating 160 mW of power.
--	On the transmit side, Analog Devices offers a choice of laser diode drivers. The ADN2871 single-loop LDD supports VCSEL (vertical-cavity surface-emitting laser) DFB (distributed feedback) and FP (Fabry-Perot) lasers, and provides over 45 percent eye margin to the 4x Fibre Channel mask. The ADN2870 dual-loop laser diode driver automatically controls DFB and FP lasers over temperature and compensates for laser aging, thus reducing or eliminating the need for expensive temperature calibration.
--	Use of Analog Device's ADuC7020 precision microcontroller allows the module function to be set in software or control more complicated and higher performance modules. On a single-chip, the microcontroller integrates a powerful 32-bit RISC core with precision data conversion technology that supports up to 16 channels of fast, 12-bit analog-to-digital conversion and up to four 12-bit digital-to-analog converters.

    About the SFP Reference Design

    The 1x/2x/4x multi-rate reference design includes an SFP board and the optics to enable immediate evaluation, speed time to market and reduce development costs. In addition, the reference design includes a host board, I(2)C support, Gerber files, object and source code for the microcontroller, a graphical user interface and technical documentation.

    Pricing and Availability

    The SFP reference design is available now. The ADN2882 TIA, ADN2892 limiting amplifier and ADN2870 dual-loop laser driver are available in production quantities now. Samples of the ADN2882 TIA are available in either die form or in a receive optical sub-assembly (ROSA). The ADN2871 single-loop laser driver will sample in February of 2005. The ADuC7020 precision microcontroller is sampling now and will be available in production quantities in July 2005. The chipset will sell in high volume for $3.90.
