Data Compliant 115.2 kbps
Infrared Transceiver
Data Sheet
Description
The HSDL-3000 is a small form
factor infrared (IR) 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 Physical Layer Specifica-
tions 1.3 and is IEC 825-Class 1
eye safe.
The HSDL-3000 can be shut down
completely to achieve very low
power consumption. In the shut-
down 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.
The HSDL-3000 has two front
packaging type options (HSDL-
3000#007/017). Both options have
an integrated shield that helps to
ensure low EMI emission and high
immunity to EMI field, thus
enhancing reliable performance.

Marking Information
The HSDL-3000#007/017 is
marked “YYWW” on the shield
where ‘YY’ indicates the unit’s
manufacturing year, and ‘WW’
refers to the work week in which
the unit is tested.

Notes:
1. CX1 must be placed within 0.7 cm of HSDL-3000 to obtain optimum noise immunity.
2. In environments with noisy power supplies, supply rejection can be enhanced by including
CX2 as shown in ”HSDL-3000 Functional Block Diagram“on page 2.
Caution:
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 during handling and
assembly of this component to prevent damage and/or degradation, which may be induced by ESD.

Notes:
1. An in-band optical signal is a pulse/sequence where the peak wavelength,
λp,
is defined as 850 nm
≤ λp ≤
900 nm, and the pulse characteristics
are compliant with the IrDA Serial Infrared Physical Layer Link Specification.

EI

.
3. Latency is defined as the time from the last TXD light output pulse until the receiver has recovered full sensitivity.
4. Receiver wake up time is measured from V
CC
power on to valid RXD output.
5. Transmitter wake up time is measured from V
CC
power on to valid light output in response to a TXD pulse.
6. Maximum optical pulse width is defined as the maximum time that the LED will remain on. This is to prevent the long turn on time for the LED.
