Description
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 large-
core POF with core sizes up to 980
µm.
Such optical
fiber types are often found in Automotive, Industrial
and Residential networks.
Reliability assurance is based on Telcordia GR-468-
CORE 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.
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.
