COMMUNICATIONS COMPONENTS
Access PIN-TIA Receivers for 155 Mb/s and 622 Mb/s
EDR 51xx Series
Applications
• Single mode 155 Mb/s (EDR 512x) and
622 Mb/s (EDR 515x) ATM receivers
• Campus network backbone
- Add/drop multiplexers
- Digital loop carriers
- Digital crossconnects
- Optical networking
• Enterprise network backbone
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.
