HSDL-3208
Ultra Small Profile Package IrDA® Data Compliant
Low Power 115.2 kbit/s Infrared Transceiver
Data Sheet
Description
The HSDL-3208 is an ultra-small low cost infrared
transceiver module that provides the interface be-
tween logic and infrared (IR) signals for through air,
serial, half-duplex IR data link. The module is compli-
ant to IrDA Physical Layer Specifications version 1.4
Low Power from 9.6 kbit/s to 115.2 kbit/s with extended
link distance. It is IEC 825-Class 1 eye safe and able to
switch to Low Tx Power Mode when programming
sequence is applied to both SD and TXD inputs.
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 battery
operated handheld products.
