DESCRIPTION
The TSOP21.., TSOP23.. series are miniaturized receivers
for infrared remote control systems. A PIN diode and a
preamplifier are assembled on a lead frame, the epoxy
package acts as an IR filter.
The demodulated output signal can directly be decoded by
a microprocessor. The main benefit of the TSOP21.. is the
compatibility to all IR remote control data formats. The
TSOP23.. is optimized to better suppress spurious pulses
from fluorescent lamps, LCD TVs or plasma displays.
This component has not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP21.., TSOP23.. series are designed to suppress
spurious output pulses due to noise or disturbance signals.
Data and disturbance signals can be distinguished by the
devices according to carrier frequency, burst length and
envelope duty cycle. The data signal should be close to the
band-pass center frequency (e.g. 38 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the TSOP21.., TSOP23.. in
the presence of a disturbance signal, the sensitivity of the
receiver is reduced to insure that no spurious pulses are
present at the output. Some examples of disturbance
signals which are suppressed are:
• DC light (e.g. from tungsten bulb or sunlight)
• Continuous signals at any frequency
• Modulated IR signals from common fluorescent lamps
(example of noise pattern is shown in figure 14 or
figure 15)
