Definitions:
In the Vishay transceiver data sheets 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
MIR and FIR were implemented with IrPhy 1.1, fol-
lowed by IrPhy 1.2, adding the SIR Low Power Stan-
dard. 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.
