General Description
The VSC7710 integrated PIN Photodetector/Transimpedance Amplifiers provides a highly integrated solu-
tion 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-III process are fully utilized to provide a
very high bandwidth and low noise amplifier. The PIN detector is 75
µ
m in diameter. The detector bias is sup-
plied internally eliminating the need for a separate bias connection. The sensitivity, duty cycle distortion and jit-
ter meet or exceed all Fibre Channel and Gigabit Ethernet application requirements. Parts are available in flat-
windowed or lensed packages.
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 900-1600 nm spectral range which exhibit
very high performance and ease of use.
