The TFDU4300 is a low profile (2.5 mm) infrared transceiver module with independent logic reference voltage (Vlogic) for low voltage IO interfacing. It is compliant to the latest IrDA physical layer standard for fast infrared data communication, supporting IrDA speeds up to 115.2 kbit/s (SIR) and carrier based remote control. The transceiver module consists of a PIN photodiode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution in a single package. This device covers an
