1. Description
The IC T2526 is a complete IR receiver for data communication developed and opti-
mized for use in carrier-frequency-modulated transmission applications. The IC offers
highest sensitivity as well as highest suppression of noise from daylight and lamps.
The T2526 is available with broadest range of frequencies (30, 33, 36, 37, 38, 40, 44,
56, 76 kHz) and 5 different noise suppression regulation types (standard, lamp, noise,
short burst, data rate) covering requirements of high-end remote control solutions
(please refer to selection guide available for T2525/T2526). The T2526 operates in a
supply voltage range of 2.7V to 5.5V.
The function of the T2526 can be described using the block diagram of 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 f0 which is equivalent to the
chosen carrier frequency of the input signal The demodulator is used first 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 the present environmental conditions (ambient light, modulated lamps
etc.). Other special features are used to adapt to the current application to secure best
transmission quality.
