3 / 4 page Oplink Communications, Inc. Application Notes Optical Power Monitor Interface Circuit Typical DATA output Eye Pattern Typical Jitter Tolerance Measurement Timing Diagram Typical Jitter Transfer Function External Monitor Resistor (about 3 Kohm) APD/PIN Current Monitor SRC-48 PM (Pin 3) VCC DATA CLOCK T CSP SRC48 R3.2009.04.30 3 The receiver converts the incident optical power to a photocurrent via a high performance P-I-N photodiode (Short and Intermediate Reach version) or an avalanche photodiode (Long Reach version).The photocurrent can be monitored via thevoltagedropacrossanexternalresistorconnectedbetween PM and V CC. The APD Bias Voltage is internally generated from the +5 V supply by a low noise DC-DC converter. The APD Bias Voltage is temperature compensated to ensure stable operation over the entire operating temperature range.the entire operating temperature range. BothDATAandCLOCKoutputsaredifferentialsignalsdesigned to be AC-coupled into 50 ohm load. Transmission lines are recommended for best performance. The Signal Detect circuit monitors the level of the incoming optical signal and generates a logic LOW signal at the SIGNAL DETECT+ output when insufficient photocurrent is produced. No termination resistor is required for the SIGNAL DETECT outputs. |
