TFDT5500

The TFDU5100, TFDS5500, and TFDT5500 are a family of lowpower infrared transceiver modules compliant to the IrDA 1.2 standard for fast infrared data communication, supporting IrDA speeds up to 1.152 Mbit/s (Medium IR, MIR), HP-SIR, Sharp ASK and carrier based remote control modes up to 500 kHz. Integrated within the transceiver modules are a photo PIN diode, infrared emitter (IRED), and a lowpower CMOS control IC to provide a total frontend solution in a single package. Vishay Telefunken's transceivers are available in three package options, including our Baby Face package (as TFDU5100), the smallest MIR 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 chips 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 to implement a complete solution.
