FCI-H125G-010
1.25Gbps Silicon Photodetector / Transimpedance Amplifier
FCI-H125G-010 is a low noise, high bandwidth photodetector plus transimpedance amplifier designed for short wavelength (850nm) high speed fiber optic data communications. The hybrid incorporates a 250µm diameter large sensing area, high sensitivity silicon photodetector. It also includes a high gain transimpedance amplifier producing a differential output voltage for latching to post amplifiers used in electrooptical receivers and transceivers for Gigabit Ethernet and Fibre Channel applications up to 1.25Gbps over multi-mode fiber. The photodetector converts the light into an electrical signal while the output voltage increases with light input. This is achieved by a single +3.3V to +5V positive power supply.
