General Description
The VSC7711 Transimpedance Amplifiers provide a high performance solution for amplifying high speed photodetector output signals 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 detector bias is supplied on-chip eliminating the need for a separate bias connection. The sensitivity, duty cycle distortion and jitter meet or exceed all Fibre Channel and Gigabit Ethernet requirements.
