AGILENT HSDL

Agilent HSDL-3000 # 007/017
IrDA® 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 Specifications 1.3 and is IEC 825-Class 1
eye safe.
Application Support Information
The Application Engineering
group is available to assist you
with the technical understanding
associated with HSDL-3000
infrared transceiver module. You
can contact them through your
local sales representatives for
additional details.
The HSDL-3000 can be shut down
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.
Applications

– PDAs
– Notebooks
– Printers
• Mobile telecom
– Cellular phones
– Pagers

• Electronic wallet
• Medical and industry data
collection
The HSDL-3000 has two front
packaging type options (HSDL3000#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.
2. For in-band signals 2.4 kbps to 115.2 kbps where 3.6 µW/cm2 ≤ EI ≤ 500 mW/cm2.
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 VCC 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.

The reflow profile is a straight
line representation of a nominal
temperature profile for a convective reflow solder process. The
temperature profile is divided into
four process zones, each with
different ∆T/∆time temperature
change rates. The ∆T/∆time rates
are detailed in the above table.
The temperatures are measured at
the component to printed-circuit
board connections.
In process zone P1, the PC
board and HSDL-3000
castellation I/O pins are heated to
a temperature of 125 °C to
activate the flux in the solder
paste. The temperature ramp up
rate, R1, is limited to 4 °C per
second to allow for even heating
of both the PC board and
HSDL-3000 castellation I/O pins.
9
Process zone P2 should be of
sufficient time duration (> 60
seconds) to dry the solder paste.
The temperature is raised to a
level just below the liquidus point
of the solder, usually 170°C
(338°F).
unreliable connections. The
temperature is then rapidly
reduced to a point below the solidus temperature of the solder,
usually 170°C (338°F), to allow
the solder within the connections
to freeze solid.
Process zone P3 is the solder
reflow zone. In zone P3, the
temperature is quickly raised
above the liquidus point of solder
to 230°C (446°F) for optimum
results. The dwell time above the
liquidus point of solder should be
between 15 and 90 seconds. It
usually takes about 15 seconds to
assure proper coalescing of the
solder balls into liquid solder and
the formation of good solder
connections. Beyond a dwell time
of 90 seconds, the intermetallic
growth within the solder connections becomes excessive, resulting in the formation of weak and
Process zone P4 is the cool
down after solder freeze. The
cool down rate, R5, from the
liquidus point of the solder to
25°C (77°F) should not exceed
–3°C per second maximum. This
limitation is necessary to allow
the PC board and HSDL-3000
castellation I/O pins to change
dimensions evenly, putting minimal stresses on the HSDL-3000
transceiver.

Recommended Optical Port Design
To insure IrDA compliance, some
constraints on the height and
width of the window exist. The
minimum dimensions ensure that
the IrDA cone angles are met
without vignetting. The maximum dimensions minimize the
effects of stray light. The minimum size corresponds to a cone
angle of 30 degrees, the maximum, to a cone angle of 60
degrees.
Z
Y
X is the width of the window, Y is
the height of the window, and Z is
the distance from the HSDL-3000
to the back of the window.
The distance from the center of
the LED lens to the center of the
photodiode lens is 5.80 mm. The
equations for the size of the
window are as follows:
X = 5.80 +2(Z + D) tan θ
Y = 2(Z + D) tan θ
Where θ is the required half angle
for viewing. For the IrDA minimum, it is 15 degrees, for the
IrDA maximum it is 30 degrees.
(D is the depth of the LED image
inside the part, 3.2 mm from the
Tx lens vertex). These equations
result in the following tables and

Shape of the Window
From an optics standpoint, the
window should be flat. This ensures that the window will not
alter either the radiation pattern
of the LED, or the receive pattern
of the photodiode.
material chosen for the window,
the radius of the front and back
curves, and the distance from the
back surface to the transceiver.
Once these items are known, a
lens design can be made which
will eliminate the effect of the
front surface curve.
If the window must be curved for
mechanical design reasons, place
a curve on the back side of the
window that has the same radius
as the front side. While this will
not completely eliminate the lens
effect of the front curved surface,
it will reduce the effects. The
amount of change in the radiation
pattern is dependent upon the
The following drawings show the
effects of a curved window on the
radiation pattern. In all cases,
the center thickness of the window is 1.5 mm, the window is
made of polycarbonate plastic,
and the distance from the transceiver to the back surface of the
window is 3 mm.

Test Methods
Background Light and Electromagnetic Field
There are four ambient interference conditions in which the
receiver is to operate correctly.
The conditions are to be applied
separately:
1. Electromagnetic field:
3 V/m maximum (please refer
to IEC 61000-4-3 severity level
3 for details).
2. Sunlight:
10 kilolux maximum at the
optical port. This is simulated
with an IR source having a
peak wavelength within the
range of 850 nm to 900 nm
and a spectral width of less
than 50 nm biased to provide
490 µW/cm2 (with no modulation) at the optical port. The
light source faces the optical
port.
This simulates sunlight within
the IrDA spectral range. The
effect of longer wavelength
radation is covered by the incandescent condition.

3. Incandescent Lighting:
1000 lux maximum. This is
produced with general service,
tungsten-filament, gas-filled,
inside frosted lamps in the 60
Watt to 100 Watt range to
generate 1000 lux over the
horizontal surface on which
the equipment under test rests.
The light sources are above the
test area. The source is
expected to have a filament
temperature in the 2700 to
3050 Kelvin range and a spectral peak in the 850 to 1050
nm range.
4. Fluorescent Lighting:
1000 lux maximum. This is
simulated with an IR source
having a peak wavelength
within the range of 850 nm to
900 nm and a spectral width of
less than 50 nm biased and
modulated to provide an
optical square wave signal
(0 µW/cm2 minimum and
0.3 µW/cm2 peak amplitude
with 10% to 90% rise and fall
times less than or equal to
100 ns) over the horizontal
surface on which the equipment under test rests. The
light sources are above the test
area. The frequency of the
optical signal is swept over the
frequency range from 20 kHz
to 200 kHz.
Due to the variety of fluorescent lamps and the range of IR
emissions, this condition is not
expected to cover all circumstances. It will provide a
common floor for IrDA
operation.
