ANADIGICS PIN-TIA Delivers High Sensitivity Required in High-Speed Gigabit Ethernet and Fiber Channel Systems.

WARREN, N.J.--(BUSINESS WIRE)--Dec. 22, 1998--

This new device integrates a PIN

diode and a transimpedance amplifier (TIA)

for use in 1300-nm Fiber-Optic communications networks.

In response to the increasing number of 1300-nm fiber-optic installations in Gigabit speed networks, ANADIGICS, Inc. has introduced the AMT121302T46F integrated photodetector and transimpedance amplifier (TIA) for use in the front end of fiber-optic receivers. Integrating a PIN diode (which converts light into an electrical signal) and a TIA (which amplifies that electrical signal), the new device features high sensitivity and impressive overload performance. It also provides the robust characteristics required to support current and emerging high-speed data communication systems, such as Gigabit Ethernet (1.250 Gb/s) and Fiber Channel (1.064 Gb/s).

High sensitivity allows increased signal transmission distance and improved reliability, and the AMT121302T46F features typical sensitivity of -25dBm, offering performance better than Gigabit Ethernet and Fiber Channel specifications. This GaAs device also handles very loud signals that may result from a short transmitter/receiver path, featuring optical overload protection of better than -3 dBm.

The AMT121302T46F offers superior performance that will enable engineers to develop exceptional high-speed data communications designs. "We are very pleased with the bandwidth, sensitivity, and responsivity of our new product. This is the kind of performance that will give our customers' products a competitive edge in the communications marketplace," said Phil Wallace, Vice President of Fiber Optic Products.

While producing a clean eye, this device also delivers high gain of better than 1000 Volts/Watt. An automatic gain control circuit enables the AMT121302T46F to handle strong input signals.

"Using an integrated PIN-TIA allows customers to take advantage of high sensitivity and better performance when designing fiber-optic transceivers," notes Daniel Trepanier, Sales Manager for Fiber Optics Products. "As a leading manufacturer of TIAs for fiber telecommunications and as a leader in high volume analog GaAs ICs, ANADIGICS is well positioned to provide market leading PIN-TIAs for premises network applications."

Housed in a TO-46 flat window package, the AMT121302T46F PIN-TIA requires a 5.0V supply and draws a typical current of 35 mA. The part operates across 0 to +70 degrees Celsius temperatures. It is priced at $40 in quantities of 1,000.

The devices are manufactured at the company's state-of-the-art facility in New Jersey and are 100% optically tested before shipping.
