Description

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 IrDA IrPHY specification version 1.3 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 full SIR compliance (range > 1 m in full 15° cone).

Vishay Telefunken's TFDS4402 transceiver represents a novel package option with the same chipset as TFDU4202 enabling a minimized package height over the PCB of only 1.8 mm and nevertheless offering a full 1 m transmission range. The output intensity is adjustable by an external resistor to save current consumption in low power applications.This chipset is also available in the well known babyface package (TFDU4102). For operating only in the distance limited low power range (20 cm/ 30 cm), TFDU4201 with built-in current control is recommended.
