grounded load.
FCI-H125G-010
1.25Gbps Silicon Photodetector / Transimpedance Amplifier
FCI-H15G-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 50µm 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 electro-optical receivers and transceivers
for Gigabit Ethernet and Fibre Channel applications up to 1.5Gbps 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 +.V to +5V positive power supply. These devices are available
in 4 pin TO-46 metal packages with either a double sided AR coated window
cap or an integrated lens cap. The 50µm diameter sensing area eases
fiber alignment for connectorization or receptacle attachment. Furthermore,
the proximity of the transimpedance amplifier to the photodetector lowers
the capacitance associated with long traces, therefore allowing higher
bandwidth and sensitivity.
