TFDU8108
Vishay Semiconductors
Very Fast Infrared Transceiver Module (VFIR, 16 Mbit/s)
IrDA
Serial Interface Compatible
2.7 V to 5.5 V Supply Voltage Range
Description
The TFDU8108 transceiver is part of a family of low
power consumption infrared transceiver modules. It is
compliant to the IrDA physical layer standard for VFIR
infrared data communication, supporting IrDA speeds
up to 16 Mbit/s (VFIR) and carrier based remote con-
trol modes up to 2 MHz. Integrated within the trans-
ceiver module are a PIN photodiode, an infrared emit-
ter (IRED), and a low-power control IC.
At a minimum, a Vcc bypass capacitor is the only
external component required implementing a com-
plete solution. For limiting the transceiver’s internal
power dissipation one additional resistor might be
necessary. The transceiver can be operated with
logic I/O voltages as low as 1.8 V.
