    -XFP chipset and accompanying reference design saves development
    time and eases interoperability issues for optical networking
    systems.

    Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications, today announced that it will demonstrate a new XFP (10 gigabit small form factor pluggable) optical transceiver chipset and reference design at the Optical Fiber Conference show in Anaheim, Calif. on March 7. XFP is rapidly becoming the leading standard for optical transceiver modules that connect to 10 Gbps (gigabit per second) ports, such as those used in Ethernet, Fibre Channel, and SONET/SDH protocol applications. XFP is protocol agnostic, uses less than one-third the power, and is one-third the size of an MSA (Multisource Agreement) transceiver with parallel interface. It is also "hot pluggable", meaning the system does not have to be shut down prior to installation. For the fast growing XFP optical transceiver market, ADI's XFP chipset eases interoperability challenges by reducing the jitter requirements of the transceiver module's transmit and receive interface--a critical element for making transceiver modules from different manufacturers work together in the same optical networking system--and the accompanying reference design enables reduced time-to-market.
    "ADI's XFP chipset reduces the risk for optical transceiver manufacturers who have fewer resources and less time to bring next-generation 10 Gbps products to market," said Peter Real, product line director for Analog Devices' Networking and Interface Products Group. "The high performance of this chipset has the potential to speed the adoption of XFP by solving remaining technical and interoperability hurdles. The very clean jitter performance of the signal conditioner reduces the performance requirements of the transmit and receive ASICs that interface to the optical transceiver module."
    For optical network engineers who must implement difficult 10 Gbps transceiver designs, ADI's XFP chipset achieves optical eye margins of greater than 20% over temperature to SONET specifications, has receive sensitivities of better than -19 dBm, and offers a signal conditioner with best-in-class jitter performance that greatly exceeds XFP specifications and provides added margin to ease interoperability issues. The accompanying reference kit, which includes an XFP optical transceiver, reduces time-to-market by enabling complete evaluation of the whole chipset.

    Analog Devices' XFP Optical Transceiver Chipset

    ADI's XFP chipset includes the following Analog Devices' products designed to work seamlessly together:

--	Signal Conditioner: The ADN2928 dual XFP signal conditioner retimes the signal in the module on both the transmit and receive paths. The dual signal conditioner has unparalleled jitter performance with jitter generation of 6 mUI rms at OC-192, jitter tolerance of 0.6 UI p-p at 10 MHz for OC-192 and jitter transfer bandwidth of 2.0 MHz, all exceeding XFP specifications. Single transmit (ADN2827) and receive (ADN2826) versions will be available later this year, offering the same jitter performance in separate devices for easy customization of the module layout. For more, visit www.analog.com/ADN2928.
--	Transimpedance Amplifier: On the receive path, the ADN2821 is a 3.3 V, 10 Gbps TIA (transimpedance amplifier) with only 1.1 iA of total integrated noise, allowing receiver sensitivities of -19 dBm to be achieved in a standard TO-46 can package. The device supports PIN diodes, dissipates only 150 mW of power and has a receive optical sub-assembly (ROSA) reference design that supports the XMD standard. For more, visit www.analog.com/ADN2821.
--	Laser Drivers: Two laser drivers support DFB (distributed feedback), FP (Fabry-Perot) and vertical-cavity side-emitting lasers (VCSELs). The ADN2525 3.3 V, 10 Gbps Active Terminated Differential LDD (laser diode driver) supports DFB and FP lasers, achieving optical eye margins of greater than 20% over temperature for SONET and greater than 40% for Ethernet, with typical power consumption for the laser and the LDD of only 750 mW. The ADN2530 10 Gbps Active Terminated Differential VCSEL driver dissipates only 300 mW for the laser and the LDD, and is pin-compatible with the ADN2525. The active termination feature contained in both devices results in a superior match to transmission lines, and exceptional eye quality at very low power. For more, visit www.analog.com/ADN2525 and www.analog.com/ADN2530.
--	Precision Analog Microcontroller: Use of Analog Devices' ADuC7020 precision analog microcontroller allows the module's functionality to be programmed in software, and supports control of 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 eight channels of fast, 12-bit analog-to-digital conversion and up to four 12-bit digital-to-analog converters.
