DESCRIPTION
These products 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 be directly decoded by a
microprocessor. The TSOP321.., TSOP341.. are compatible
with all common IR remote control data formats. The
TSOP323.., TSOP343.. are optimized to better suppress
spurious pulses from energy saving fluorescent lamps. The
TSOP325.., TSOP345.. have an excellent noise suppression. It
is immune to dimmed LCD backlighting and any fluorescent
lamps. AGC3 and AGC5 may also suppress some data signals
in case of continuous transmission.
This component has not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
These products 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 IR receiver 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 noise from fluorescent lamps with electronic
ballasts (see figure 14 or figure 15)
