Description

The TFDU8108 transceiver is part of a family of lowpower consumption infrared transceiver modules compliant to the IrDA physical layer standard for VFIR infrared data communication, supporting IrDA speeds up to 16 Mbit/s (VFIR) and carrier based remote control modes up to 2 MHz. Integrated within the transceiver module are a PIN photodiode, an infrared emitter (IRED), and a low-power BiCMOS control IC to provide a total front-end solution in a single package.

Vishay Semiconductors VFIR transceivers are available in the BabyFace package. This provides flexibility for a variety of applications and space constraints. 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 V_CC bypass capacitor is the only external component required implementing a complete solution. For limiting the transceiver internal power dissipation one additional resistor might be necessary. The transceiver can be operated with logic I/O voltages as low as 1.5 V. The functionality of the device is equivalent to the TFDU6108 with the VFIR functionality added. The IRED current is programmable to different levels,    no external current limiting resistor is necessary.
