An increasing number of
infra-red remote control
circuits in video recorders
and TV sets have an
integrated infra-red
receiver/demodulator. The
advantages of such modules
are clear: a smalI, less
complex, circuit, and lower
production costs.
Furthermore, the combination
of an IR receiver and a
demodulator in one package
increases the reliability of the
remote control.
This Siemens application note
takes a further look at the
SFH505A.
