Description
The ZL60015 is a compact optical receiver designed for 1310/1550 nm based SONET/SDH OC-48/STM-16 applications. It is ideally suited for use in multi-rate transceiver modules as well as general optical communication applications with data rates up to 3.125 Gbps. The optical receiver is assembled in a single compact TO-46 package and contains an optimized InGaAs PIN photodiode in combination with a low-noise transimpedance amplifier (TIA). It includes an additional pin allowing the photocurrent from the detector to be directly monitored. The receiver operates using a single 3.3 V power supply. It is designed for use with a 9 m single-mode fiber. Reliability assurance is based on Telcordia GR-468CORE and the part is compliant to the EU directive 2002/95/EC issued 27 January 2003 [RoHS].

Application Guidelines
ESD Handling
Data Sheet
The receiver is sensitive to electrostatic discharges. When handling the device, precaution for ESD sensitive devices should be taken. These precautions include use of ESD protected work area with wrist straps, controlled work benches, floors etc. Photodiode Monitor The Monitor pin is a current sink output signal directly proportional to the optical input power. To convert the current from the Monitor pin to a voltage a resistor to VCC should be used. Note to maintain linearity the Monitor pin should, when in use, be maintained at a bias > 1V. Host Board Layout Example Included in the example of a Host Board Layout (Figure 4) are power supply decoupling capacitors. These are recommended for optimal performance of the receiver. A filter is also included to minimise power supply noise. A suggested post-amplifier is shown, namely MAX3748. Alternative post-amplifiers may also be used by the customer.
