Description
The IC ATA2516 is a complete IR receiver for data communication systems. The
device is developed and optimized for use in carrier frequency modulated transmis-
sion applications. Its function can be described using the block diagram in Figure 1 on
page 2. 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 application. After
amplification by a Controlled Gain Amplifier (CGA), the signals pass a tuned inte-
grated narrow bandpass filter with a center frequency f
carrier frequency of the input signal. The demodulator is used to convert the input
burst signal to 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
changing environmental conditions (ambient light, modulated lamps etc.). A 7-bit digi-
tal-to-analog converter is used to adjust the gain of the controlled gain amplifier. Other
special features serve to adapt to the current application to secure best transmission
quality. The ATA2516 operates in a voltage supply range of 4.5 V - 5.5 V.
