HSDL-3220
IrDA
®
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
interface 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 pro-
ducing 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.
