General Description
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 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.
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.
