DescriptionThe TFDU6108 is an infrared transceiver module compliant to the latest IrDA standard for fast infrared data communication, supporting IrDA speeds up to 4.0 Mbit/s (FIR), and carrier based remote control mod s up to 2 MHz. Integrated within the transceiver module are a PIN photodiode, an infrared emitter (IRED), and a low-power CMOS control IC to provide a total front-end solution in a single package.
These FIR transceivers with an integrated serial interface are compliant with the IrDA "Serial Interface Standard for Transceiver Control". The transceivers are capable of directly interfacing with a wide variety of I/O devices, which perform the modulation/ demodulation function. At a minimum, a VCC bypass capacitor is the only external component required implementing a complete solution. For limiting the transceiver internal power dissipation one additional resistor might be added. The transceiver can be operated with logic I/O voltages as low as 1.5 V.
