Description

The TFDU6102E, TFDS6402, TFDS6502E, TFDT6502E are a family of lowpower infrared transceiver modules compliant to the IrDA physical layer standard for fast infrared data communication, supporting IrDA speeds up to 4.0 Mbit/s (FIR), HP-SIR, Sharp ASK and carrier based remote control modes up to 2 MHz. Integrated within the transceiver
modules are a photo PIN diode, an infrared emitter (IRED), and a lowpower CMOS control IC to provide a total frontend solution in a single package.

Vishay Telefunken's FIR transceivers are available in four package options, including our Baby Face package (TFDU6102E), the standard setting, once smallest FIR transceiver available on the market. This wide selection 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, including National Semiconductor's PC87338, PC87108 and PC87109, SMC's FDC37C669, FDC37N769 and CAM35C44, and Hitachi's SH3. At a minimum, a currentlimiting resistor in series with the infrared emitter and a VCC bypass capacitor are the only external components required implementing a complete solution.
