TFDS4400
Vishay Semiconductors
SIR Transceiver Module (115.2 kbit/s)
2.7 V to 5.5 V
Description
The TFDS4400 is a low–power infrared transceiver 1.8 mm and nevertheless offering a full 1m IrDA 1.2
module compliant to the IrDA physical layer standard transmission range. The transceiver is capable of
for infrared data communication, supporting IrDA directly interfacing with a wide variety of I/O chips
speeds up to 115.2 kbit/s (SIR), HP-SIR, and carrier which perform the modulation/demodulation function,
based remote control modes up to 100 kHz. Integrated including National Semiconductor’s PC87338,
within the transceiver module are a photo PIN diode, PC87108 and PC87109, SMC’s FDC37C669,
infrared emitter (IRED), and a low–power control IC to FDC37N769 and CAM35C44, and Hitachi’s SH3. At a
