Definitions:
In the Vishay transceiver datasheets the following
nomenclature is used for defining the IrDA operating modes:
SIR: 2.4 kbit/s to 115.2 kbit/s, equivalent to the basic serial
infrared standard with the physical layer version IrPhy 1.0
MIR: 576 kbit/s to 1152 kbit/s
FIR: 4 Mbit/s
VFIR: 16 Mbit/s
IrDA, the infrared data association, implemented MIR and
FIR with IrPHY 1.1, followed by IrPhY 1.2, adding the SIR low
power standard. IrPhY 1.3 extended the low power option to
MIR and FIR and VFIR was added with IrPhY 1.4. A new
version of the standard in any case obsoletes the former
version.
