... MIN frequency in Hz. PHOTODIODE REFERRED TO POSITIVE SUPPLY Figure 3 shows the AD8015 used in a circuit where the photo- diode is referred to the positive supply. The back bias voltage on the photodiode is 1.8 V. This method of referring the photo- diode provides greater power supply noise immunity (PSRR) than referring the photodiode to the negative supply ...

... Sensitivity (minimum power level) = 541/0. 637 nW (peak) = –32.0 dBm (peak) = –35.0 dBm (average) The SONET OC-3 specification allows for a minimum power level of –31 dBm peak, or –34 dBm average. Using the AD8015 provides 1 dB margin. FDDI SENSITIVITY ANALYSIS FDDI Minimum Bandwidth = 0.7 88 MHz Total Current Noise ...

... AD8015 AC COUPLED PHOTODIODE APPLICATION FOR IMPROVED DYNAMIC RANGE AC coupling the photodiode current input to the AD8015 (Fig- ure 17) extends fiber optic receiver overload while sacri- ficing only sensitivity (increasing receiver dynamic range by 2 dB). This application results in typical overload of –4 dBm, ...
