COMMUNICATIONS COMPONENTS

Key Features

• Electro-optical

- InGaAs PIN photodiode with silicon transimpedance amplifier

- Operate on single supply

EDR 512x (5 V)

EDR 515x (3.3 V or 5 V)

- Three standard pin-out configurations

EDR 51xB - single-ended output

EDR 51xC - single-ended output with photodiode access

EDR 51xD - differential output

- Cost effective in receiver designs where sensitivity is

limited by the post-amplifier

- Shielded pre-amplifier makes it immune to crosstalk

with transmitter or to other EMI

- -40 to +85°C operating range

• Packaging

- Integrated 4-pin coaxial package

- Connector receptacle (panel or PCB mount) and fiber

pigtailed versions

- Case grounded versions

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.
