TFDU4100

TFDU4100/TFDS4500/TFDT4500 Vishay Telefunken 2.7 V to 5.5 V Serial Infrared Transceiver Module Family (SIR, 115.2 kbit/s) Description The TFDU4100, TFDS4500, and TFDT4500 are a family of low–power infrared transceiver modules compliant to the IrDA 1.2 standard for serial infrared (SIR) data communication, supporting IrDA speeds up to 115.2 kbit/s. Integrated within the transceiver modules are a photo PIN diode, infrared emitter (IRED), and a low–power analog control IC to provide a total front–end solution in a single package. Telefunken’s SIR transceivers are available in three package options, including our BabyFace package (TFDU4100), the smallest SIR 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 pulse–width modulation/demodulation function, including Telefunken’s TOIM3000/ TOIM3232. At a minimum, a current– limiting resistor in series with the infrared emitter and a VCC bypass capacitor are the only external components required to implement a complete solution.
