TFD4500 IRDA infrared interface circuit

This electronic infrared serial transceiver circuit is based on a TFDS4500 IC and can be used to transmit data from portable devices to a PC using IR and serial port .

TFD4500 it’s a low–power infrared transceiver modules for serial infrared (SIR) data communication which support IrDA speeds up to 115.2 kbit/s. In this infrared circuit transceiver it’s integrated an photo diode infrared emitter (IRED) and a low–power analog control IC.

Main features of The TFD4500 infrared transceiver are : 1.2 up to 115.2 kbit/s speed , 2.7 to 5.5 V Operating Voltage Range , Low–Power Consumption (1.3 mA Supply Current) , Power Sleep Mode ,Long Range (Up to 3.0 m at 115.2 k/bit/s) , directly interfaces with many controller devices .

The TFD infrared transceiver ca be used in applications like : Notebook Computers , Desktop PCs , PDAs , Digital Still and Video Cameras , Printers , Fax Machines, Photocopiers , Screen Projectors and other .
