Vishay/Semiconductor's TFDU4301 is a low profile (2.5 mm) infrared transceiver module. 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 extended IrDA low power range of close to 1 m. With an external current control resistor the current can be adjusted for shorter ranges.
The RXD output pulse width is independent of the optical input pulse width and stays always at a fixed pulse width, making the device optimal for standard endecs. TFDU4301 has a tri-state output and is floating in shut-down mode with a weak pull-up.
