SIR Transceiver Module (115.2 kbit/s)
2.7 V to 5.5 V
Description
The TFDS4400 is a low–power infrared transceiver
module compliant to the IrDA physical layer standard
for infrared data communication, supporting IrDA
speeds up to 115.2 kbit/s (SIR), HP-SIR, and carrier
based remote control modes up to 100 kHz. Integrated
within the transceiver module are a photo PIN diode,
infrared emitter (IRED), and a low–power control IC to
provide a total front–end solution in a single package.
Vishay Semiconductors TFDS4400 transceiver
represents a novel package option enabling a
minimized package height over the PCB of only
1.8 mm and nevertheless offering a full 1m IrDA 1.2
transmission range. The transceiver is capable of
directly interfacing with a wide variety of I/O chips
which perform the modulation/demodulation function,
including National Semiconductor’s PC87338,
PC87108 and PC87109, SMC’s FDC37C669,
FDC37N769 and CAM35C44, and Hitachi’s SH3. At a
minimum, a current– limiting resistor in series with the
infrared emitter and a V_CC bypass capacitor are the
only external components required to implement a
complete solution.
