VSC7809

VITESSE SEMICONDUCTOR CORPORATION Advance Product Information VSC7809 Photodetector/Transimpedance Amplifier Family for Optical Communication Features Integrated Photodetector/Transimpedance Amplifier Optimized for High-Speed Optical Communications Applications Fibre Channel/Gigabit Ethernet Compatible www.DataSheet4U.comHigh Bandwidth Low Input Noise Equivalent Power Large Optically Active Area Single 3.3V Power Supply Part Number VSC7809 Data Rate 1.25Gb/s Bandwidth (MHz) 800 Input Noise (µW rms) 1.4 Optically Active Area (µm diameter) 100 General Description The VSC7809 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, tempera...
