Description
The HSDL-3208 is an ultra-small 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. It is IEC 825-Class 1 eye safe and able to switch to Low Tx Power Mode when programming sequence is applied to both SD and TXD inputs.
