Analog Diagnostics Functions (Top = -10°C to 70 °C, VCC = 3.00 to 3.60 Volts) Parameter Transmitter Monitor photodiode current monitor Laser bias current monitor Receiver Received photocurrent Photodiode responsivity Applied voltage at PD pin Symbol Pmon+, PmonBmon+, BmonRpd R Vpd Min 0 0 Typ Max Vcc Vcc Unit V V Notes 1 2 0 0.5 2.4 0.9 1 1.0 Vcc mA A/W V 3 3 Notes: 1. Pins 19 and 20 provide an analog voltage output proportional to the monitor photodiode current, per the following formula: IBIAS = .V(Pmon+ - Pmon-) / 200Ω. The figure below shows the equivalent circuit. 2. Pins 17 and 18 provide an analog voltage output proportional to the laser bias current, per the following formula: IBIAS = .V(Bmon+ - Bmon-) / 10Ω. The figure below shows the equivalent circuit. 3. Pin 1 is used to monitor the received photocurrent. It must be connected to a positive voltage within the range specified above. The current that flows into this pin is the received photocurrent. The received power is given by the photocurrent multiplied by the photodiode responsivity.
