Description

The TFDU6102 is a low-power infrared transceiver module compliant to the latest IrDA physical layer standard for fast infrared data communication, supporting IrDA speeds up to 4.0 Mbit/s (FIR), and carrier based remote control modes up to 2 MHz. Integrated within the transceiver module are a PIN photodiode, an  nfrared emitter (IRED), and a low-power CMOS control IC to provide a total front-end solution in a single package.

Vishay FIR transceivers are available in different package options, including this BabyFace package (TFDU6102). This wide selection provides flexibility for a variety of applications and space constraints. The transceivers are capable of directly interfacing with a wide variety of I/O devices which perform the modulation/ demodulation function, including National Semiconductor's PC87338, PC87108 and PC8 7109, SMC's FDC37C669, FDC37N769 and CAM35C44, and Hitachi's SH3. TFDU6102 has a tristate output and is floating in shut-down mode with a weak pull-up.
