Description
The TFDS4400 is a low–power infrared transceiver module compliant to the IrDA physical layer standard for infrared data communication, supporting IrDA speeds up to 115.2 kbit/s (SIR), HP-SIR, and carrier based remote control modes up to 100 kHz. Integrated within the transceiver module are a photo PIN diode, infrared emitter (IRED), and a low–power control IC to provide a total front–end solution in a single package.
