HSDL-3002
IrDA® Data Compliant Low Power 115.2 kbit/s with
Remote Control Transmission Infrared Transceiver
Data Sheet
Description
The HSDL-3002 is a small form factor single enhanced
infrared (IR) transceiver module that provides the
combination of (1) interface between logic and IR
signals for through-air, serial, half-duplex IR data link,
and (2) IR remote control transmission operating at
940 nm for universal remote control applications.
For infrared data communication, the HSDL-3002
provides the flexibility of Low Power SIR applications
and remote control applications depending on the
application circuit designs as outlined in the Application
Circuit section. The transceiver is compliant to IrDA
Physical Layer Specifications version 1.4 from 9.6
kbit/s to 115.2 kbit/s and it is IEC 825-Class 1 Eye Safe.
The HSDL-3002 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. Such features are ideal for battery operated
handheld products.

Connected to an external switching transistor. Do not float
the input pin of the swithcing transistor.
Logic high turns on the LED. If held high longer than
~50
µs,
the LED is turned off. TXD (IrDA) must be driven
either high or low. DO NOT leave the pin floating.
Output is at low pulse response when light pulse is seen.

Q1
Notes:
1. R1 is used to optimize the performance of the 870 nm LED, while R2 is the current limiting resistor for the 940 nm RC LED.
2. CX1 must be placed within 0.7 cm of HSDL-3002 to obtain optimum noise immunity.
3. In environment with noisy power supplies, supply rejection can be enhanced by including CX2 as shown in Figure 1.

EI = In-Band Infrared Intensity at detector
Notes:
4. In-Band EI
≤
115.2 kb/s.
5. Logic Low is a pulsed response. The condition is maintained for duration dependent on the pattern and strength of the incident intensity.
6. To maintain low shutdown current, TXD need to be driven high or low and not left floating. The Remote Control Input should be tied low.
CAUTION:
The BiCMOS inherent to this design of this component increases the component’s susceptibility to
damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and
assembly of this component to prevent damage and/or degradation, which may be induced by ESD.
