Access PIN-TIA Receivers for 155 Mb/s and 622 Mb/s (PDF, 0.21 MB)
The EDR 51xx Series incorporates a 75 μm InGaAs PIN photodetector coupled with a low cost BiCMOS transimpedance amplifier (TIA) designed to operate at 155 Mb/s (EDR 512x) or 622 Mb/s (EDR 515x). The PIN transduces optical power into current with high efficiency. The TIA converts the current signal into a voltage signal with a very low input noise current contribution. The EDR 512x TIA also integrates an automatic gain control (AGC) circuit which decreases the light to voltage conversion factor when the average incident optical power is relatively high.
The EDR 51xx Series are assembled in rugged coaxial packages. They are available with a connector receptacle or as a single mode fiber pigtail. Standard choices for connector receptacles are LC, SC and FC. In addition, the EDR 51xx Series are available in several standard pin-out configurations. The EDR 51xB is the simplest configuration and provides a single ended output. The EDR 51xC provides access to the photodiode current for those customers who need to design an alarm circuit. The EDR 51xD provides a differential output for higher gain performance without sacrifice to sensitivity and bandwidth.
