The VSC7709 integrated PIN Photodetector/Transimpedance Amplifier 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 process are fully utilized to provide a very high bandwidth and low noise amplifier. The PIN detector is 75m 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. The VSC7709 is available in flat-windowed or lensed packages. The transimpedance amplifier is also available in bare die form. 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-optic receivers for the 900nm-1600nm spectral range which exhibit very high performance and ease of use.
