HSDL-3600 #007/#008/#107
IrDA® Compliant 4 Mb/s 3 V Infrared Transceiver
Data Sheet
Description
The HSDL-3600 is a low-profile infrared transceiver
module that provides interface between logic and IR
signals for through-air, serial, half-duplex IR data link.
The module is compliant to IrDA Data Physical Layer
Specifications 1.1 and IEC825-Class 1 Eye Safe.
The HSDL-3600 contains a high-speed and high-
efficiency 870 nm LED, a silicon PIN diode, and an
integrated circuit. The IC contains an LED driver and a
receiver providing a single output (RXD) for all data
rates supported.

The HSDL-3600 can be completely
shut down to achieve very low
power consumption. In the shut
down mode, the PIN diode will be
inactive and thus producing very
little photo-current even under
very bright ambient light. The
HSDL–3600 also incorporated the
capability for adjustable optical
power. With two programming
pins; MODE 0 and MODE 1, the
optical power output can be
adjusted lower when the nominal
desired link distance is one-third
or two-third of the full IrDA link.
The HSDL-3600 comes in three
package options; the front view
option (HSDL-3600#007/#017),
the front view guide pin option
(HSDL-3600#107/#117), and the
top view option (HSDL-3600#008/
#018). All options come with
integrated shield that helps to
ensure low EMI emission and high
immunity to EMI field, thus
enhancing reliable performance.

EI = In-Band Infrared Intensity at detector
Notes:
1. In-Band EI
≤
115.2 kb/s and FIR_SEL = 0.
2. In-Band EI
≥
0.576 Mb/s and FIR_SEL = 1.
3. Logic Low is a pulsed response. The condition is maintained for duration dependent on the pattern and strength of the incident intensity.
4. To maintain low shutdown current, TXD needs to be driven high or low and not left floating.

Notes:
5. CX1 must be placed within 0.7 cm of the HSDL-3600 to obtain optimum noise immunity.
6. In environments with noisy power supplies, supply rejection performance can be enhanced by including CX2,
as shown in “HSDL-3600 Functional Block Diagram” in page 3.

Marking Information
The HSDL-3600#007/017 is marked
“3600YYWW’ on the shield where “YY”
indicates the unit’s manufacturing year,
and “WW” refers to the work week in
which the unit is tested.
The HSDL-3600#008/018 is marked a
“black” dot on the shield.

CAUTIONS:
The BiCMOS inherent to the 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.
