The TIR1000 serial infrared (SIR) encoder/
decoder is a CMOS device which encodes and
decodes bit data in conformance with the IrDA
specification.
A transceiver device is needed to interface to the photo-sensitive diode (PIN) and the light emitting diode (LED).
A UART is needed to interface to the serial data lines.
