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, 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 ver-
sion.
With introducing the updated versions the old versions are obso-
lete. Therefore the only valid IrDA standard is the actual version
IrPhy 1.4 (in Oct. 2002).
