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.
Ma
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.
