SFH551-1 - Receiver

Download the SFH551-1 datasheet PDF. This datasheet also covers the SFH551 variant, as both devices belong to the same receiver family and are provided as variant models within a single manufacturer datasheet.

General Description

The SFH551/1-1 receiver is a transimpedance amplifier with an integrated photodiode and TTL open-collector output stage.

The active area of this detector combined with the molded microlens gives an efficient coupling from the end of the polymer optical fiber.

SFH551/1-1 and SFH551/1-1V Receiver with Digital Output Stage for Polymer Optical Fiber Applications Data Sheet Description The SFH551/1-1 receiver is a transimpedance amplifier with an integrated photodiode and TTL open-collector output stage. The active area of this detector combined with the molded microlens gives an efficient coupling from the end of the polymer optical fiber. This receiver enables data rates up to 5 MBd and works with the Avago SFH757 transmitter diode. The SFH551/1-1 is fully DC coupled and therefore no line code is needed. The internal Schmitt trigger ensures stable output states over the whole dynamic range. If light with intensity above the threshold level is coupled into the SFH551/1-1, the electrical output will be logical “low” and vice versa.
