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.
