■ General Description
The photo IC is a complete IR receiver for data communication developed and optimized for use in carrier
frequency modulated transmission applications. Its function can be described using the block diagram (see
figure 1). The input stage meets two main functions. First, it provides a suitable bias voltage for the PIN diode.
Secondly, the pulsed photo-current signals are transformed into a voltage by a special circuit which is optimized
for low noise applications. After amplification by a controlled gain amplifier (CGA), the signals have to pass a
tuned integrated narrow bandpass filter.The demodulator is used to convert the input butst signal into a digital
envelope output pulse and to evaluate the signal information quality,I.e. unwanted pulses will be suppressed at
the output pin. All this is done by means of an integrated dynamic feedback circuit which varies the gain as a
function of the present environ mental condition (ambient light, modulated lamps etc.). Other special features
are used to adapt to the current application to secure best transmission quality.
