Integrated Low Profile Transceiver Module
for Telecom Applications – IrDA Standard
DescriptionThe 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 distance limited low power
range (20 cm/ 30 cm), TFDU4201 with built-in current
control is recommended. For these devices see the
equivalent data sheets.
