VITESSE SEMICONDUCTOR CORPORATION Data Sheet VSC7810 Photodetector/Transimpedance Amplifier Family for Optical Communication Features Integrated Photodetector/Transimpedance Amplifier Optimized for High-Speed Optical Communications Applications Integrated AGC www.DataSheet4U.com Fibre Channel/Gigabit Ethernet Compatible High Bandwidth Low Input Noise Equivalent Power Large Optically Active Area Single 5V Power Supply Part Number VSC7810 Data Rate Full Speed: 1.25Gb/s Bandwidth (MHz) 1200 Input Noise (µW rms) 0.45 Optically Active Area (µm diameter) 100 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 pro...
