 Data Compliant Low Power 4.0 Mbit/s  
Infrared Transceiver
Data Sheet
Description
The  HSDL-3220  is  a  new  generation  low  profile  high 
speed infrared transceiver module that provides inter-
face between logic and IR signals for through-air, serial, 
half-duplex IR data-link. The module is fully compliant 
to  IrDA  Physical  Layer  specification  version  1.4  low 
power from 9.6kbit/s to 4.0 Mbit/s (FIR) and is IEC825-
Class 1 Eye Safe.
The HSDL-3220 can be shutdown completely to achieve 
very low power consumption. In the shutdown mode, 
the PIN diode will be inactive and thus producing very 
little  photocurrent  even  under  very  bright  ambient 
light.  It  is  also  designed  to  interface  to  input/output 
logic circuits as low as 1.8V. These features are ideal for 
mobile devices that require low power consumption.
