GENERAL DESCRIPTION

The VSC7810 integrated Photodetector/Transimpedance Amplifier provides a highly integrated solution for

converting light from a fiber optic communications channel into a differential output voltage. The benefits of Vitesse

Semiconductor’s Gallium Arsenide H-GaAs process are fully utilized to provide very high bandwidth and low noise

in a product with a large optically active area for easy alignment. The sensitivity, duty cycle distortion and jitter meet

or exceed all Fibre Channel and Gigabit Ethernet application requirements. Parts are available in either die form, flat-

windowed packages or in ball-lens packages.

By using a metal-semiconductor-metal (MSM) photodetector with a monolithic integrated transimpedance amplifier,

the input capacitance is lowered which allows for a larger optically active area than in discrete photodetectors.

Integration also allows superior tracking over process, temperature and voltage between the photodetector and the

amplifier, resulting in higher performance. The VSC7810 can easily be used in developing Fibre Channel Electro-

Optic Receivers which exhibit very high performance and ease of use.
