Description
This optical receiver is designed for SDI (Serial Digital
Interface) digital television transmission systems
where optical fiber replaces coaxial cable, to increase
transmission distance. It is designed in conjunction
with the ANSI/SMPTE 259 M standard and is capable
of handling DC-unbalanced (pathological) signals.
The receiver operates at 3.3 V and contains an InGaAs
PIN photodiode and a transimpedance amplifier with
AGC (Automatic Gain Control), assembled in a TO-46
package. Its double-lens optical system is designed for
use with single-mode fiber as well as multi-mode fiber
with a core diameter up to 62.5
µm.
Reliability
assurance is based on Telecordia GR-468-CORE.

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.
Power Supply Filter
Power Supply decoupling capacitors are recommended for optimal performance of the receiver. A filter is
recommended to minimise power supply noise. See Figure 6.
