TFDU4101 Vishay Semiconductors Infrared Transceiver Module (SIR, 115.2 kbit/s) for IrDA®Applications
●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.
●FEATURES
■Operates from 2.4 V to 5.5 V within specification over full temperature range from - 30 °C to + 85 °C
■ Split power supply, transmitter and receiver can be operated from two power supplies with relaxed requirements saving costs, US - patent no. 6,157,476
■Low power consumption (< 0.12 mA supply current in receive mode, no signal)
■ Power shutdown mode (< 4 μA shutdown current in full temperature range, up to 85 °C, < 10 nA at 25 °C)
■ Surface mount package (L x W x H in mm): 9.7 × 4.7 × 4
■ High efficiency emitter
■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 as e. g. TOIM4232
■ Tri-state-receiver output, floating in shut down with a weak pull-up
■Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)
