Appendix C: General Application Guide for the HSDL-3602
Infrared IrDA Compliant 4 Mb/s Transceiver
Description
The HSDL-3602 wide voltage operating range infrared
transceiver is a low-cost and small form factor that is
designed to address the mobile computing market such
as notebooks, printers and LAN access as well as small
embedded mobile products such as digital cameras,
cellular phones, and PDAs. It is fully compliant to IrDA
1.1 specification up to 4 Mb/s, and supports HP-SIR,
Sharp ASK, and TV Remote modes. The design of the
HSDL-3602 also includes the following unique features:
Low passive component count.
Adjustable Optical Power Management (full, 2/3, 1/3
power).
Shutdown mode for low power consumption require-
ment.
Single-receive output for all data rates.
Adjustable Optical Power Management
The HSDL-3602 transmitter offers user-adjustable opti-
cal power levels. The use of two logic-level mode-select
input pins, MODE 0 and MODE 1, offers shutdown mode
as well as three transmit power levels as shown in the
following Table. The power levels are setup to corre-
spond nominally to maximum, two-third, and one-third
of the transmission distance. This unique feature allows
lower optical power to be transmitted at shorter link
distances to reduce power consumption.
There are 2 basic means to adjust the optical power of
the HSDL-3602:
Dynamic: This implementation enables the transceiver
pair to adjust their transmitter power according to the
link distance. However, this requires the IrDA protocol
stack (mainly the IrLAP layer) to be modified. Please
contact Agilent Application group for further details.
Static: Pre-program the ROM BIOS of the system (e.g.
notebook PC, digital camera, cell phones, or PDA) to
allow the end user to select the desired optical power
during the system setup stage.

Resistor R1 should be selected to provide the appropri-
ate peak pulse LED current over different ranges of Vcc.
The recommended R1 for the voltage range of 2.7 V to
3.3 V is 2.2 while for 3.0 V to 3.6 V is 2.7 . The HSDL-
3602 typically provides 250 mW/sr of intensity at the
recommended minimum peak pulse LED current of 400
mA.
Interface to Recommended I/O chips
The HSDL-3602’s TXD data input is buffered to allow
for CMOS drive levels. No peaking circuit or capacitor is
required.
Data rate from 9.6 kb/s up to 4 Mb/s is available at the
RXD pin. The FIR_SEL pin selects the data rate that is
receivable through RXD. Data rates up to 115.2 kb/s can
be received if FIR_SEL is set to logic low. Data rates up
to 4 Mb/s can be received if FIR_SEL is set to logic high.
Software driver is necessary to program the FIR_SEL to
low or high at a given data rate.
4 Mb/s IR link distance of greater than 1.5 meters have
been demonstrated using typical HSDL-3602 units with
National Semiconductor’s PC87109 3 V Endec and Super
I/Os, and the SMC Super I/O chips.
(A) National Semiconductor Super I/O and Infrared
Controller
For National Semiconductor Super I/O and Infrared
Controller chips, IR link can be realized with the
following connections:
Connect IRTX of the National Super I/O or IR Control-
ler to TXD (pin 9) of the HSDL-3602.
Connect IRRX1 of the National Super I/O or IR Control-
ler to RXD (pin 8) of the HSDL-3602.
Connect IRSL0 of the National Super I/O or IR Control-
ler to FIR_SEL (pin 3) of the HSDL-3602.
Please refer to the table below for the IR pin assign-
ments for the National Super I/O and IR Controllers that
support IrDA 1.1 up to 4 Mb/s:
