General Description

The VSC7807 integrated Photodetector/Transimpedance Amplifier provides a highly integrated solution for converting 850nm 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. The VSC7807 is available in either die form, flat-windowed packages or ball-lens packages.
