User Manual
The miniaturized TFDU4202 is an ideal transceiver for applications in telecommunications like mobile phones and pagers. The device is mechanically designed for lowest profile with a height of only 2.8 mm. The infrared transceiver is compatible to the latest IrDA® IrPHY specification up to a data rate of 115 kbit/s. At lower operating voltages up to 3.3 V the transceiver can be operated without external current limiting resistor to achieve a range > 1 m. The added feature is a split power supply for IRED driver (Vccp) and ASIC (Vccp). For operating only in the limited distance, low power range (20 cm/ 30 cm), TFDU4201 with built-in current control is recommended. For this device see the appropriate data sheet.
