Infrared Transceiver
Data Sheet
Description
The HSDL-3005 is a small form factor enhanced
infrared (IR) transceiver available in Front View
and Top View modules. It 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.
For IR data communication, the HSDL-3005
provides the flexibility of Low Power SIR
applications and Remote Control applications with
no external components needed for the selection
of the type of application. The transceiver is com-
pliant to IrDA® Physical Layer Specifications
version 1.4 Low Power from 9.6 kbit/s to 115.2
kbit/s (SIR) and it is IEC 825-Class 1 Eye Safe.
The HSDL-3005 has very low idle current and 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 such as PDAs and mobile
phones.

Notes:
1. Tied through external resistor, R1, to VLED from 2.4 to 4.5 Volts.
2. No Connection.
3. Logic high turns on the IrDA LED. If held HIGH longer than ~50
µs,
the IrDA LED is turned off.
TxD_IrDA must be driven either HIGH or LOW. Do not leave the pin floating.
4. Output is at LOW pulse response when light pulse is seen.
5. Complete shutdown TxD_IrDA, RxD_IrDA, and PIN diode.
6. Regulated, 2.4 to 3.6 Volts.
7. Logic high turns on the RC LED. If held HIGH longer than ~50
µs,
the RC LED is turned off.
TxD_RC must be driven either HIGH or LOW. Do not leave the pin floating.
8. Tie this pin to system ground.
9. Tie to system ground via a low inductance trace. For best performance, do not tie it to the
HSDL-3005 GND pin directly.

Different Remote Control
Configuration for HSDL-3005
The HSDL-3005 can operate in
the single-TxD programmable
mode or the two-TxD direct
transmission mode.
(A) Single-TxD
Programmable Mode
In the single-TxD programmable
mode, only one input pin
(TxD_IrDA input pin) is used.
The transceiver is in default
mode (IrDA) when powered up.
User needs to apply the
following programming
sequence to both the TxD_IrDA
and SD inputs to enable the
transceiver to operate in either
the IrDA or remote control
mode.
