MARCH 12, 2009 -- Maxim Integrated Products (search Lightwave for Maxim) has introduced the MAX3798, a single-chip VCSEL driver and limiting-amplifier targeted for SFP+ Fibre Channel and Ethernet applications. Fabricated using Maxim's MBIC3 IC technology, this device is designed to deliver greater than 10-Gbps performance, a wide range of receiver- and transmitter-programmable features, and 320 mW of power consumption.

Combining the functions of two chips into one, the MAX3798 offers a low-cost, low-power approcah for both Fibre Channel (1x/2x/4x/8x) and Ethernet 10GBASE-SR transmission systems, thus simplifying transceiver BOM for module manufacturers, Maxim says.

A 3-wire digital interface provides a wide range of programmable features to optimize performance. Programmable receive functions include data rate, LOS threshold, LOS squelch, LOS polarity, CML output level, signal path polarity, slew-rate control, de-emphasis, and mode-select change time. Programmable transmit functions include modulation current, bias current, polarity, de-emphasis, eye-crossing adjustment, and eye safety control.

The MAX3798 is fully specified for operation over the -40 degrees Celsius to +85 degrees Celsius temperature range, and is available in a 5x5-mm, 32-pin TQFN package. Prices start at $6.18 (10,000-up, FOB USA).
