Vishay Semiconductors
Integrated Low Profile Transceiver Module for Telecom
Applications - IrDA Standard
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
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.
