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 pliant to the Ir DA 1.2 standard for serial infrared (SIR) data munication, supporting Ir DA 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 Baby Face 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 ponents required to implement a plete solution.
