Pin Descriptions The RA192 10 Gbits/s fiber-optic receiver consists of a high-speed APD photodetector and a wide-band linear preamp in a pigtailed, butterfly metal package. The fiber pigtail is internally beveled for low return loss and is available with SC, FC, LC, or MU optical connectors. It is designed for use in single-mode, high-speed telecommunication applications at the SONET OC-192 and the ITU-T SDH STM-64 data rate of 9.95328 Gb/s.

The operating case temperature range for the receiver is 0 C to 70 C. The dc levels of the differential outputs can be adjusted relative to each other for optimum sensitivity in noisy, amplified systems. These outputs are centered around a dc level of typically -0.45 V when the two outputs are dc-coupled to 50 loads. The two outputs can also be ac coupled. If slice level control is not needed, the FBIN pin (pin 14) should be left open. The TIA requires only a -5.2 V power supply for operation. The APD photodiode requires a nominal bias voltage of 25 V to 36 V at less than 1 mA.

Preliminary Data Sheet May 2002 RA192 OC-192/STM-64 APD Lightwave Receiver 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 operations section of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

APD optimum bias voltage (VOP) differs from device to device and is provided with each device. 2. The resistance of the thermistor is inversely proportional to the temperature. The temperature can be calculated from the resistance value using the Steinhart-Hart equation: 1/T = A + B ln(R) + C ln(R)3; where T is the temperature in Kelvin degrees, R is the thermistor resistance value in Ohms, and A, B, and C are constants: A = 1.0267 x 10-3, B = 2.565 x 10-4, C = - 4.5421 x 10-8. 4 Agere Systems Inc.
