The link distance testing was
done using typical HSDL-3003
units with SMC’s FDC37C669
and FDC37N769 Super I/O
controllers. An IrDA link distance
of up to 70 cm was demonstrated.
Remote Control Operation
The HSDL-3003 is spectrally
suited to universal remote control
transmission function at 940 nm
typically. Remote control
applications are not governed by
any standards, owing to which
there are numerous remote
control codes in the market.
Each of these standards results in

receiver modules with different
sensitivities, depending on the
carrier frequencies and
responsivity to the incident light
wavelength.
Based on a survey of some
commonly used remote control
receiver modules, the irradiance
is found to be in the range of
0.05 ~ 0.07 mW/cm2. Based on
a typical irradiance of 0.05 mW/
cm2 and 0.075 mW/cm2 and
turning on the RC LED, a typical
link distance of 8 m and 7 m is
achieved typically.
