COMMUNICATIONS COMPONENTS Access PIN-TIA Receivers for 155 Mb/s and 622 Mb/s EDR 51xx Series 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 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 • 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.

The EDR 51xx Series exceed Long Reach OC-3 (EDR 512x) and OC-12 (EDR 515x) SONET receiver specifications and are ideal for transceiver designs or board level discrete designs. Applications include receivers for digital cross connects, digital loop carriers, add/drop multiplexers, optical network units and switches and routers for LAN and WAN backbones. External Circuitry When designing the EDR 51xx Series into an optical receiver, standard high speed printed circuit board design practices should be observed. For example, bypassing of the power supply is recommended so as to reduce noise that appears at the output of the PIN-TIA. If signal traces are relatively long, use impedance matching techniques to maximize power transfer from the PIN-TIA to its load: for microstrip design, assume 70 ohms (EDR 512x) and 60 ohms (EDR 515x) as the output impedance for the PIN-TIA. Note as well that the output of the PIN-TIA is DC-coupled. Since most applications require AC-coupled stages, a high-Q RF chip capacitor should be placed on the output of the module. To eliminate oscillations, the PIN-TIA should be mounted on a circuit board with a large, low impedance ground plane. All the PIN-TIA leads should be made as short as possible in order to reduce excess inductances. As a general rule, receiver bandwidth requirements need only be greater than about 1/3 of the bit rate at which they are intended to operate. A receiver for a 155 Mb/s system must have a bandwidth greater than 110 MHz. A receiver for a 622 Mb/s system must have a bandwidth greater than 415 MHz. On the other hand, any frequency component above 110 MHz for 155 Mb/s systems or above 415 MHz for 622 Mb/s systems contributes excess noise to the output. The excess noise needlessly reduces the sensitivity of the receiver. The receiver designer may therefore improve the PIN-TIA sensitivity by placing a low pass noise filter on the output. Performance Highlights The EDR 51x Series offer a sensitivity of better than -36 dBm (EDR 512x) or -30 dBm (EDR 515x) with appropriate filtering and a minimum overload of 0 dBm (EDR 512x) or -7 dBm (EDR 515x). This large dynamic range makes these products ideal for both long and short range applications. A time constant of 4 milliseconds makes the AGC circuit of the EDR 512x models very stable, even during reception of the longest streams of high or low logic levels. The EDR 51x Series operate over -40 to +85°C. The EDR 51x Series provide significant benefits over hybrid designs and 14-pin receivers. Integration of the TIA with the PIN detector onto the TO-46 header reduces parasitic capacitances and lead inductances. The TO-52 cap hermetically seals the hybrid and provides EMI shielding especially from the transmitter circuit. These advantages improve sensitivity over designs that place the amplifier outside the capsule and away from the detector. The EDR 51x Series, which have four pins, are advantageous over 14-pin receivers because they require less board space and fewer electrical connections. In addition, the EDR 51xx Series operate from a single power supply, even in the pin-out configuration which provides photodiode current monitoring. The smaller form factor and the need for a single power supply make the EDR 51x Series a less expensive, high performance alternative to other kinds of optical receivers.
