ZL60038 650-nm, 125 Mbps Pin Preamplifier for Plastic Optical Fiber Data Sheet August 2005 Ordering Information ZL60038TBDE, TO-46 with lens The ZL60038 is also available assembled in standard optical receptacles: ZL60038TDDE, ZL60038TEDE, ZL60038TFDE, ZL60038TGDE, Features • Data rates up to 250 Mbps • Large-area Si photodiode • TIA with AGC • Hermetically sealed package (MIL-STD 883) • Single 3.3 V power supply in ST receptacle in SC receptacle in FC receptacle in SMA receptacle In addition the ZL60038 can also be supplied in customer-specific receptacles, on request -40°C to +85°C Description Applications • Plastic Optical Fiber (POF) based optical communication links • IEEE Fast Ethernet • IEEE 1394b Firewire • Automotive, Industrial and Residential Networking The ZL60038 is a compact optical receiver designed for 650-nm plastic optical fiber (POF) based optical communication systems with data rates up to 250 Mbps. The optical receiver is assembled in a single compact TO-46 package and contains an optimized large-area Si PIN photodiode in combination with a transimpedance amplifier (TIA) with automatic gain control (AGC). The receiver operates using a single 3.3 V power supply. It is designed for use with largecore POF with core sizes up to 980 µm. Such optical fiber types are often found in Automotive, Industrial and Residential networks. VCC Data Out Data Out 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].

ZL60038 Data Sheet Application Guidelines ESD Handling 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. 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 recommended post-amplifier is shown, namely Maxim MAX3969. Alternative post-amplifiers may also be used by the customer. Vcc 100pF 100nF 10uH 50 Ohm 100nF Fiber 50 Ohm ZL60038 100nF Figure 4 - Host Board Layout Example 4 Zarlink Semiconductor Inc.
