Vishay TFDU4300 Specifications and User Guide

TFDU4300 Vishay Semiconductors

Infrared Transceiver Module (SIR, 115.2 kbit/s) for Ir DA® applications Description The TFDU4300 is a low profile (2.5 mm) infrared transceiver module with independent logic reference voltage (Vlogic) for low voltage IO interfacing. It is compliant to the latest Ir DA® physical layer standard for fast infrared data communication, supporting Ir DA® speeds up to 115.2 kbit/s (SIR) and carrier based remote control. The transceiver module con- sists of a PIN photodiode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution in a single package. This device covers an extended Ir DA® low power The RXD output pulse width is independent of the

range of close to 1 m. With an external current control optical input pulse width and stays always at a fixed resistor the current can be adjusted for shorter pulse width thus making the device optimum for stan- ranges. dard Endecs.
