The TFDU4101-TR3 is an Infrared Transceiver module compliant to the latest IrDA® physical layer standard for fast infrared data communication, supporting IrDA speeds up to 115.2kbit/s (SIR) and carrier based remote control modes. Integrated within the transceiver module is a photo pin diode, an infrared emitter (IRED) and a low-power control IC to provide a total front-end solution in a single package. This device covers the full IrDA range of more than 1m using the internal intensity control. With one external current control resistor the current can be adjusted for shorter ranges saving operating current operating in IrDA low power mode.
