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 obsoletes the former ver-

sion.

Absolute Maximum Ratings

Reference point Ground (pin 8) unless otherwise noted.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

*) Due to the internal measures the device is a "class1" device. It will not exceed the IrDA intensity limit of 500 mW/sr.
