VSC7710

• Integrated Photodetector/Transimpedance Amplifier Family Optimized for High Speed Optical Communications Applications
• Integrated AGC
• Fibre Channel and Gigabit Ethernet
• High Bandwidth
• Low Input Noise Equivalent Power
• Single 5V Supply

The VSC7710 integrated PIN Photodetector/Transimpedance Amplifiers provides a highly integrated solution 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 75µm in diameter. The detector bias is supplied internally eliminating the need for a separate bias connection. The sensitivity, duty cycle distortion and jitter meet or exceed all Fibre Channel and Gigabit Ethernet application requirements. Parts are available in flatwindowed or lensed packages.

The use of a photodetector and transimpedance amplifier hybrid, reduces the input capacitance, resulting in igher sensitivity and bandwidth and improved speed of response. These parts can easily be used in developing ibre Channel and Gigabit Ethernet electro-optic Receivers for the 900-1600 nm spectral range which exhibit ery high performance and ease of use.
