Vitesse expands optoelectronics device family

February 12, 2001–Camarillo, California–Vitesse Semiconductor Corp. today announced the expansion of its optoelectronic product offering with the addition of 10 new products targeted at next-generation OC-48 SONET/SDH DWDM systems up to 3.125 Gb/s, Gigabit Ethernet, and Fibre Channel equipment manufacturers.

The new products are specifically targeted to transceiver and transponder applications. They provide the module designer with a high degree of flexibility with a multitude of transimpediance amplifiers, lifting amplifiers, limiting amplifiers, and laser drivers to optimize sensitivity with minimum chip count and power dissipation.

“The designers of new communications equipment need to optimize a fiber’s capability by having a longer module reach, excess margin on the data eye opening, and a low dispersion penalty,” says Ray Milano, vice president and general manager of optoelectronic products at Vistesse. “These new devices provide this and more in low-cost packages or die form that are guaranteed to run at today’s higher required temperatures. Thorough testing at the maximum operating temperature ensures that users will be able to maximize the yield of their module and board assemblies. These products are also designed to work seamlessly with Vitesse’s wide array of physical layer devices, thereby reducing design time and chip count requirements and maximizing performance.”

The new products include laser drivers with automatic power control; 3.125 Gb/s limiting amplifiers with loss of signal detect; 3.125 Gb/s transimpediance amplifier and limiting amplifiers; limiting amplifier and laser drivers; 2.125 Gb/s photodiode/transimpediance amplifiers; and 1.25 Gb/s photodiode/transimpediance amplifiers.
