Data Sheet, Rev. 1 September 2001 R480-Type Lightwave Receiver with CML Data Output for up to 2.488 Gbits/s Applications Applications s Telecommunications: — Inter- and intraoffice SONET/SDH — Subscriber loop — Metropolitan area networks High-speed data communications s Description The R480-Type 2.5 Gbits/s lightwave receiver is designed for use in SONET and synchronous digital hierarchy (SDH) telecommunications applications up to OC-48 and STM-16 data rates, and high-speed data communications applications. The receiver converts received optical signals in the range of 1.2 µm to 1.6 µm wavelength into differential CML data outputs. The receiver consists of either an InGaAs APD or PIN photodetector (depending on model selected), a transimpedance amplifier, and a limiting amplifier that provides differential CML data output. A TTL compatible link status flag signal indicates when there is a loss of optical signal. The receiver is manufactured in a low-profile, pigtailed, 24-pin plastic DIP package. It requires a single, 5.0 V power supply. The APD version has the added benefit of containing the high-voltage supply internal to the receiver. This internal supply also provides the necessary temperature compensation for the APD. An analog photodetector monitor provides a voltage proportional to the optical input level voltage (OILV). Manufactured in a low-profile, 24-pin package, the R480-Type receiver features either an avalanche or PIN photodetector, a transimpedance amplifier, and a limiting amplifier IC.

Reliability and Qualification Program for built-in quality SONET/SDH compatible for OC-48/STM-16 data rate s s s s s s R480-Type Lightwave Receiver with CML Data Output for up to 2.488 Gbits/s Applications Data Sheet, Rev. 1 September 2001 Flag Output When the incoming optical signal falls below the linkstatus switching threshold, the FLAG output is asserted and the FLAG output logic level changes from a TTL low to a TTL high. Receiver Processing The R480-Type receiver devices can withstand normal wave-soldering processes. The complete receiver module is not hermetically sealed; therefore, it should not be immersed in, or sprayed with, any solutions. The optical connector process cap deformation temperature is 85 °C. The receiver pins can be wave soldered at 250 °C for 10 seconds. Pin Information Table 1.

Take proper precautions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A (Dec. 1988). Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD. Agere Systems employs a human-body model (HBM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard HBM (resistance = 1.5 kΩ, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. * Pins labeled NIC have no internal connection. † Pins designated as no user connect (NUC) are connected internally. The user should not make any connections to these pins. ‡ The loss of signal (LOS) FLAG output is a logic level that indicates the presence or absence of a minimum acceptable level of optical input. A TTL logic HIGH indicates the absence of a valid optical input signal. § Analog optical input level voltage (OILV) is proportional to the optical input power. Installation Considerations Although the receiver has been designed with ruggedness in mind, care should be used during handling. The optical connector should be kept free from dust. The optical connector process cap should be kept in place as a dust cover when the device is not connected to a cable. If contamination is present on the optical connector, the use of canned air with a extension tube should remove any loose debris. Other cleaning procedures are outlined in the Cleaning Fiber Optic Assemblies Technical Note (TN95-010LWP). The cable should be handled conservatively, with no excessive axial pulling or lateral tugging. Handling Precautions The R480-Type receiver is manufactured with a 39 in. ± 4 in. (100 cm ± 10 cm) single-mode or multimode fiber pigtail. SC, FC/PC, LC, and MU connectors are offered on standard versions. Other optical connector options are available on special order. Please contact an Agere Systems’ Account Manager for availability and ordering information. The minimum fiber bending radius is 1.5 inches (38 mm). 2 Agere Systems Inc. Data Sheet, Rev. 1 September 2001 R480-Type Lightwave Receiver with CML Data Output for up to 2.488 Gbits/s Applications Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Data output traces must be controlled-impedance lines and the termination impedance must match the line impedance. Avoid 90° bends in the traces. Paired lines (i.e., DATA and DATA) must be equal in length. Data output lines should be as short and straight as possible and should be shielded from noise sources to prevent noise from feeding back into the receiver. Use high-quality multilayer printed-wiring boards. A ground plane should occupy the area directly beneath the receiver. 1 µH +5 V 0.1 µF NOTE 2 8, 22 VCC 4, 7, 9, 12, 14—17, 19, 20 50 Ω TRANSMISSION LINE (2X) DATA DATA 3 OILV 10 11 23 0.1 µF NOTE 1 50 Ω 2.2 µF + 15 µF s s LOS (FLAG) 1-934(C)d Note 1: Data outputs must be ac-coupled on customer board. Use a 0.1 µF chip capacitor with a low ESR. For optimum receiver performance, both data outputs must be terminated in equivalent loads, even if one of the outputs is not being used. Note 2: The 0.1 µF VCC power supply bypass capacitors should be high-quality, low ESR chip capacitors that are located as close as possible to the appropriate power supply leads and should provide a low-inductance path to the ground plane.
