Description
The OPF560 series receiver is a low cost
solution for high speed fiber optic
communication designs.
The output of the receiver is an analog,
low impedance, emitter follower voltage
source capable of driving an amplifier or
level translating circuitry. This allows the
subsequent circuitry to use the device in
either the analog mode or translated to
ECL/TTL levels for use in a digital mode
at data rates up to 155MBaud.
The receiver is comprised of a high
speed, low noise, photodiode coupled to
a transimpedance amplifier which
produces an output voltage proportional
to the input light amplitude. This hybrid
approach solves many of the problems of
high speed data link designs by placing a
pre-amplifier close to the photodiode.
The amplification of the transimpedance
amplifier makes the output signal much
less susceptible to EMI.
An AC coupled receiver application
circuit is shown. Both the 10 ohm
resistor and by-pass capacitor are
critical.
