This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operations section for extended periods of time may affect reliability. NOTICE: The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation to equipment, take normal ESD precautions when handling this product.

T2TIA = T2MEASURED - T2OPTICAL NOTES 1. PR is the average optical power at the fiber face. 2. PR,OMA is the peak to peak optical power at the fiber face (Optical Modulation Amplitude) PR ,OMA ≡ 2 PR (ER − 1) ER + 1 where ER is the extinction ratio (linear) of the optical source. 3. Bandwidth and Low Frequency Cutoff are measured with a small signal sinusoidal light source with –10dBm average power 4. Sensitivity is measured with an optical source with an extinction ratio of 3dB. For sensitivity measurements at 2 and 4Gbps, bandwidth limiting of the TIA is assumed to be implemented at the front end of the post amplifier. 5. Rise/Fall times are corrected for optical source Rise/Fall 6. Value shown is with no external power supply filtering. 7. Group delay is a sensitive measurement to package interface, and includes the effects of PD, TIA and package. Measurement is made with TO leads as short as possible. 8. DJTIA is specified as contributed DJ by the TIA, obtained from DJ2TIA = DJ2TOTAL - DJ2OPTICAL 9. RJTIA is specified as contributed DJ by the TIA, obtained from RJ2TIA = RJ2TOTAL - RJ2OPTICAL 10. The electrical performance of the ROSA is dependent upon the quality of the electrical connection between the TO can and the circuit board. AOC cannot guarantee all performance specifications for parts without the flex circuit attached.
