The miniaturized TFDU4203 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 up to a data rate of 115 kbit/s.
The transceiver can be operated without external
current limiting resistor to achieve full SIR compliance
(range > 1 m in full ±15° cone).
