VSC7710

VITESSE SEMICONDUCTOR CORPORATION Advance Product Information VSC7710 Features Integrated Photodetector/Transimpedance Amplifier Family Optimized for High Speed Optical Communications Applications Integrated AGC Fibre Channel and Gigabit Ethernet Photodetector/Transimpedance Amplifier Family for Optical Communication High Bandwidth Low Input Noise Equivalent Power Single 5V Supply Part Number VSC7710 Data Rate (Gb/s) 1.25 Bandwidth (MHz) 1300 Input Noise (µW rms) .22 Optically Active Area (µm diameter) 75 General Description The VSC7710 integrated PIN Photodetector/Transimpedance Amplifiers provides a highly integrated solution for converting 1300 nm light from a fiber optic communications channel into a differential output voltage. The benefits of Vitesse Semiconductor’s Gallium Arsenide H-GaAs-III process are fully utilized to provide a very high bandwidth and low noise amplifier. The PIN detector is 75µm in diameter. The detector bias is supplied internally eliminating the need for a separate bias connection. The sensitivity, duty cycle distortion and jitter meet or exceed all Fibre Channel and Gigabit Ethernet application requirements. Parts are available in flatwindowed or lensed packages. The use of a photodetector and transimpedance amplifier hybrid, reduces the input capacitance, resulting in higher sensitivity and bandwidth and improved speed of response. These parts can easily be used in developing Fibre Channel and Gigabit Ethernet electro-opt...
