TFDU4301 Vishay Semiconductors Infrared Transceiver Module (SIR, 115.2 kbit/s)for IrDA® Applications
●DESCRIPTION
■The TFDU4301 is a low profile(2.5 mm)infrared transceiver module.It is 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.The transceiver module consists 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 IrDA low power range of close to 1 m.With an external current control resistor the current can be adjusted for shorter ranges.
■The RXD output pulse width is independent of the optical input pulse width and stays always at a fixed pulse width thus making the device optimum for standard endecs.TFDU4301has a tri-state output and is floating in shut-down mode with a weak pull-up.
●FEATURES
■Compliant to the latest IrDA physical layer specification(9.6 kbit/s to 115.2 kbit/s)and TVremote control,bi-directional operation included
■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
