Description
The HSDL-3208 is an ultra-small
low cost infrared transceiver
module that provides the interface
between logic and infrared (IR)
signals for through air, serial, half-
duplex IR data link. The module is
compliant to IrDA Physical Layer
Specifications version 1.4 Low
Power from 9.6 kbit/s to 115.2
kbit/s with extended link distance
and it is IEC 825-Class 1 eye safe.

The HSDL-3208 can be shut
down completely to achieve very
low power consumption. In the
shutdown mode, the PIN diode
will be inactive and thus produc-
ing very little photocurrent even
under very bright ambient light.
Such features are ideal for bat-
tery operated handheld products.
