It is compliant to the latest IrDA physical layerstandard for fast Infrared data communication, supportingIrDA speeds up to kbit /s (SIR) and carrier basedremote control. The Transceiver Module consists of a PINphotodiode, an Infrared emitter (IRED), and a low-powercontrol IC to provide a total front-end solution in a device covers an extended IrDA low power range ofclose to 1 m. With an external current control resistor thecurrent can be adjusted for shorter RXD output pulse width is independent of the opticalinput pulse width and stays always at a fixed pulse width thusmaking the device optimum for standard endecs.

5 IrPhy the low power option to MIR and FIR and VFIR wasadded with IrPhy A new version of the standard in anycase obsoletes the former introducing the updated versions the old versions areobsolete. Therefore the only valid IrDA standard is the actualversion IrPhy (in Oct. 2002).PIN DESCRIPTIONPIN NUMBERFUNCTIONDESCRIPTIONI/OACTIVE1 VCC2 IRED anodeConnect IRED anode directly to the power supply (VCC2). IRED current can be decreased by adding a resistor in series between the power supply and IRED anode. A separate unregulated power supply can be used at this cathodeIRED cathode, internally connected to the driver Schmitt-Trigger input is used to transmit serial data when SD is low. An on-chip protection circuit disables the LED driver if the TXD pin is asserted for longer than 100 s.

6 The input threshold voltage adapts to and follows the logic voltage swing defined by the applied supply data output, push-pull CMOS driver output capable of driving standard CMOS or TTL loads. During transmission the RXD output is active and mirrors the transmit signal. No external pull-up or pull-down resistor is required. Floating with a weak pull-up of 500 k (typ.) in shutdown mode.
