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
version.
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).

Description
I/O
Active
IRED Anode is directly connected to a power supply. The LED current can be
decreased by adding a resistor in series between the power supply and IRED
Anode. A separate unregulated power supply can be used at this pin.
This Input is used to turn on IRED transmitter when SD is low. An on-chip
protection circuit disables the LED driver if the Txd pin is asserted for longer than
80

Received Data Output, normally stays high but goes low for a fixed duration
during received pulses. It is capable of driving a standard CMOS or TTL load.
Shutdown. Setting this pin active switches the device into shutdown mode
