SUNNYVALE, Calif. -- July 9, 2002 -- In response to the increasingly stringent low power consumption and cost-sensitive requirements of the networking market, the Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., today announced two cost-effective photo detector families for fiber to the home (FTTH) and metropolitan area network (MAN) applications. The PD739C13 Photo Detector family and PD839C4 Avalanche Photo Detector family are each capable of detecting 2.5 gigabit per second (Gbps) optical fiber transmissions using only a 3.3-volt power supply.

The new products serve the needs of a wide range of customers for short- to long-reach applications. The PD739C13 family achieves photo detection by integrating a photodiode (PD) with a transimpedance amplifier (TIA) and is designed for optical transmissions of several kilometers (km) to 30 km. The PD839C4 family integrates an avalanche photodiode (APD) with a transimpedance amplifier for 20-km to 100-km optical applications.

By leveraging existing technologies, the new products ensure high reliability while providing customers with a smooth transition to volume production and a stable source of supply. The new products maintain the same package, pin positioning, and functions as Mitsubishi Electric's 5.0-volt photo detector products, thereby making existing designs easy to upgrade and reducing the time-to-market for next-generation products.

"Mitsubishi Electric's new photo detector families cost-effectively serve a wide range of applications with extremely low power consumption and high reliability," said Daniel Chen, assistant vice president of high-frequency products for Mitsubishi Electric & Electronics USA, Inc. "The families use technology that customers will find familiar, taking much of the guesswork out of next-generation designs while keeping production lines up and running."

Packaging and Availability
Members of Mitsubishi Electric's PD739C13 Photo Detector and PD839C4 Avalanche Photo Detector families are each housed in a 5.6-mm diameter general-purpose package with an attached ball lens.
Samples of both families will be available this month, with volume production scheduled for October 2002.
