  1. USB-to-UART Bridge Controller (e.g., Silicon Labs CP2102 or Prolific PL-2303 variant): Converts USB packets to serial data.
  2. IrDA Encoder/Decoder (ENDEC) : Converts serial UART signals into pulsed infrared light. For FIR speeds, it also handles 4-PPM (Pulse Position Modulation) encoding.
  3. Infrared Transceiver (e.g., Vishay TFDU4300 or equivalent): A combined emitter (LED) and detector (photodiode) tuned to 850-900 nm wavelength. The transceiver includes a control circuit for beam current and noise filtering.
