Integrated Photo Detector Receiver for Plastic Fiber
Plastic Connector Housing
Data Sheet
Description
The SFH551/1V is a transimpedance ampli er with digital
TTL open collector output stage and integrated photodi-
ode. The active area of the detector in connection with
the molded microlens gives an e cient coupling from
the end of a plastic ber.
The receiver is fully DC coupled and therefore no line
code is needed.
The SFH551/1V includes a Schmitt trigger function to
provide stable output states over the whole dynamic
range. For optical input power levels above 6 μW typically
the electrical output will be logical “low” and vice versa.
With noise free Vcc and GND no unde ned output signal
is possible. SFH551/1 must not be used without shielding
the ambient light, because ambient light causes malfunc-
tion when reaching the threshold level, noise or complete
switching the output. Interference free transmission is
possible by using the SFH551/1V with the black plastic
connector housing.
