-Supports SFF-8472, lowers costs and provides complete optical

transmitter chip set for the MSA market.

Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications, today announced a Small Form Factor Pluggable (SFP) reference design for transceivers and transceiver modules for optical networks. ADI's SFP reference design supports SFF-8472 Digital Diagnostics and provides a complete optical transceiver chip set for the Multisource Agreement (MSA) market.

The SFP reference design targets a number of applications, including 1G/2G Fibre Channel SFP/SFF (Small Form Factor) transceivers, Gigabit Ethernet SFP/SFF transceiver modules, multirate OC3 to OC48-FEC SFP/SFF transceiver modules and, when combined with ADI's ADN28X2 family of products, 4X Fibre Channel applications. The SFP reference design provides superior performance for design engineers who design systems with data rates up to 2.7 Gbps.

"Design engineers can easily use the ADI SFP reference design to develop a best-in-class optical transceiver with minimal effort," said Peter Real, Product Line Director for Analog Devices' high-speed network group. "The dual loop laser control eliminates the need for expensive temperature calibration of the module, helping to keep costs low. When compared to the closest competition, it provides superior power and sensitivity and the flexibility of a programmable supervisor."

The corresponding chip set for the SFP reference design includes the dual loop ADN2870 laser diode driver, ADN2890 limiting amplifier, ADN2880 transimpedance amplifier and ADI's precision analog microcontroller with ARM7(R) core. Details for these individual products can be found at www.analog.com/opnet.

As part of the reference design, ADI includes board layouts, gerber files, a bill of materials, software and an evaluation board. ADI's unique dual loop laser diode driver, automatically controls laser extinction ratio over temperature and eliminates the need for expensive temperature calibration of the module, while automatically compensating for laser aging. Use of Analog Devices' precision analog microcontroller in the design allows the module function to be set in software, or to control more complicated and higher performance modules. The same board layout also supports 4X Fibre Channel applications.
