amplifiers and a quantizer.
Description:
The HSDL-1000 serial infrared
module performs low cost, low
power, point-to-point, through the
air data transfer in a serial, halfduplex mode.
The module is designed to interface directly with selected I/O
chips that incorporate logic which
performs pulse width modulation/
demodulation.
The module has been designed to

Notes:
1. EI – received in band light intensity present at detector surface.
2. Pulsed Response – Logic Low is a pulsed response. A receiver output low state VOL (RXD) is not indefinitely maintained but is instead
a pulsed response. The output low state is maintained for a duration dependent on the incident bit pattern and
incident intensity (EI).
3. The EI ≥ 3.6 µW/cm 2 condition guarantees the IrDA minimum receiver sensitivity of 4.0 µW/cm2 while allowing for 10% light loss
through a cosmetic window placed in front of the HSDL-1000. (See the Rx TH+ section at the end of this data sheet for information
on receiver sensitivity over temperature, and in the presence of ambient light.)

Rx TH+ (Receiver OnThreshold)
The maximum receiver onthreshold is equivalent to the
minimum receiver sensitivity.
Both are terms for the amount of
light signal which must be present
at the HSDL-1000 detector in
order to trigger a low pulse on the
receiver output (RXD). The IrDA
Physical Layer Specification
requires a minimum receiver
sensitivity of 4.0 µW/cm2, at a Bit
Error Rate of 10-9, and in the
presence of the 10 klux of
sunlight, 0-1000 lux of fluorescent
light, or 0-1000 lux of incandescent light. The fluorescent and
incandescent specifications
require minimum receiver
sensitivity with 1000 lux incident
onto the horizontal surface of the
IR link. The resulting amount of
fluorescent or incandescent light
actually reaching the detector
surface may vary between 0 and
500 lux depending upon the
design of the housing around the
HSDL-1000 module.
The HSDL-1000 VOL(RXD)
specification guarantees a
maximum receiver on-threshold
of EI = 3.6 µW/cm2, at a
BER ≤ 10-9, and TA = 0-70°C. The
EI = 3.6 µW/cm2 threshold
guarantees the IrDA minimum
receiver sensitivity of 4.0 µW/cm2,
while allowing for 10% light loss
through a cosmetic window
placed in front of the HSDL-1000.
The EI = 3.6 µW/cm2 threshold
also guarantees receiver sensitivity
with 10 klux of sunlight,
0-500 lux fluorescent light, or
0-500 lux of incandescent light
incident on the HSDL-1000
detector surface.
