TFDU4101-TR3

The TFDU4101-TR3 is an Infrared Transceiver Module compliant to the latest IrDA physical layer standard. It is suitable for fast infrared data communication, supporting IrDA speeds up to 115.2kbps (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 1m 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 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 tri-state output and is floating in shutdown mode with a weak pull-up.

• High efficiency emitter
• Split power supply, transmitter and receiver can be operated from two power supplies
• Low profile (universal) package capable of surface mount soldering to side and top view orientation
• Directly Interfaces with various super I/O and controller devices
• Tri-state-receiver output, floating in shut down with a weak pull-up
• Low power consumption (<0.12mA supply current in receive mode, no signal)
• Power shutdown mode
