HSDL-3021
IrDA^® Data Compliant Low Power 4.0 Mbit/s with
Remote Control Infrared Transceiver
Data Sheet
Description
The HSDL-3021 is a new generation low profile high
speed enhanced infrared (IR) transceiver module
that provides the capability of (1) interface between
logic and IR signals for through-air, serial, half-
duplex IR data link, and (2) IR remote control
transmission for universal remote control
applications. The HSDL-3021 can be used for IrDA as
well as remote control application without the need
of any additional external components for
multiplexing.
The HSDL-3021 is fully compliant to IrDA® Physical
Layer specification version 1.4 low power from 9.6
kbit/s to 4.0 Mbit/s (FIR) and IEC825 Class 1 eye
safety standards.
The HSDL-3021 can be shut down completely to
achieve very low power consumption. In the shut-
down mode, the PIN diode will be inactive and thus
produce very little photocurrent even under very
bright ambient light. It is also designed to interface to
input/output logic circuits as low as 1.5 V. These
features are ideal for battery operated mobile devices
such as PDAs and mobile phones that require low
power consumption.
