The link distance testing was
done using typical HSDL-3005
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-3005 is spectrally
suited to universal remote
control transmission function.
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.
