A CMOS flag alerts the user to a loss of signal condition when the optical input falls below an acceptable level. A single +5 Volt supply provides bias for the module’s preamplifier, and Quantizer. The photodiode may be biased to +5 Volts. All elements are integrated into fiber-coupled 1.3” X 0.635” 20 pin DIL package. The RXM-750 footprint and pinout are industry common for ease of integration. The optical signal is coupled through a 62.5 µm multimode optical fiber to a hermetic module which encases an InGaAs PiN-photodiode and preamplifier. The PiN-photodiode converts the optical signal to an electrical current. The signal is then converted to a voltage and amplified by a low noise transimpedance amplifier. Further gain is provided by the quantizer, which also provides a Flag output when the optical signal falls below an acceptable level. Figure 1.

By connecting pin 10 to a +5 Volt bias through a series resistor (e.g. 1 kΩ) received optical power can be monitored as a voltage drop across the resistor. Absolute Maximum Ratings Absolute maximum ratings are provided here as worst case and short duration exposure conditions only. Exposure to conditions more severe than the Absolute Maximum Ratings may result in permanent damage. Exposure to conditions at the Absolute Maximum Ratings for extended periods may also adversely affect device performance or reliability. Functional operation of the device is not implied at these conditions. Table 2.
