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
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 version.
Note
We apologize to use sometimes in our documentation the
abbreviation LED and the word light emitting diode instead of
infrared emitting diode (IRED) for IR-emitters. That is by definition
wrong; we are here following just a bad trend.
Typical values are for design aid only, not guaranteed nor subject to
production testing and may vary with time.
