HFD3020 Overview
The HFD3020 is a sensitive differentiating optical receiver designed for use in short distance, 850 nm fiber optic systems. The receiver uses a hybrid construction consisting of a PIN photodiode, bipolar integrated receiver circuit with internal voltage regulation and external bypass capacitor. The TTL output allows the HFD3020 to be interfaced directly with standard TTL circuits.
