The HSDL-3203 is a miniature low cost infrared transceiver module that provides the interface between logic and infrared (IR) signals for through air, serial, half-duplex IR data link. The module is compliant to IrDA Physical Layer Specifications version 1.4 Low Power from 9.6 kbit/s to 115.2 kbit/s with extended link distance and it is IEC 825-Class 1 eye safe.
The HSDL-3203 can be shutdown completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. Such features are ideal for battery operated handheld products.
