HSDL-3211
IrDA^® Data Compliant Low Power 1.15 Mbit/s
Infrared Transceiver
Data Sheet
Description
The HSDL-3211 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 1.152 Mbit/s
(MIR) and is IEC825-Class 1 Eye Safe.
The HSDL-3211 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.
