Remote Control Equipment

1. Description

The IC ATA2525 is a complete IR receiver for data communication that was devel-

oped and optimized for use in carrier-frequency-modulated transmission applications.

Its function can be described using the block diagram (see Figure 1-1 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 applications. After amplification by

a Controlled Gain Amplifier (CGA), the signals have to pass a tuned integrated narrow

bandpass filter with a center frequency f₀which is equivalent to the chosen carrier fre-

quency of the input signal. The demodulator is used to convert the input burst 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

environmental condition (ambient light, modulated lamps etc.). Other special features

are used to adapt to the current application to secure best transmission quality. The

ATA2525 operates in a supply-voltage range of 4.5V to 5.5V.
