Description

The TFDU4101 transceiver is an infrared transceiver module compliant to the latest IrDA physical layer standard for fast infrared data communication, supporting IrDA speeds up to 115.2 kbit/s (SIR), and carrier based remote control modes. Integrated within the transceiver module are a photo PIN diode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution in a single package. This device covers the full IrDA range of more than 1 m using the internal intensity control. With one external current control resistor the current can be adjusted for shorter ranges saving operating current operating in IrDA low power mode. This Vishay SIR transceiver is using the lead frame technology.

The receiver output pulse duration is independent of the optical input pulse duration and recovers always a fixed pulse duration optimum for compatibility to standard Endecs and interfaces. TFDU4101 has a tristate output and is floating in shutdown mode with a weak pull-up.
