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 dis-  
tortion 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 photo-  
detectors. Integration also allows superior tracking over process, temperature and voltage between the photode-  
tector and the amplifier, resulting in higher performance. This part can easily be used in developing Fibre  
Channel Electro-Optic Receivers which exhibit very high performance and ease of use.
