e3
• Improved immunity against ambient light
• Capable of side or top view
• Two lenses for high sensitivity and wide receiving angle

WEEE 2002/96/EC
• Insensitive to supply voltage ripple and noise
DESCRIPTION
The TSOP852..,TSOP854 series are two lens miniaturized
receiver modules for infrared remote control systems. One
PIN diode per lens and a preamplifier are assembled on a
PCB, the epoxy lens cap is designed as an IR filter.
The demodulated output signal can be directly decoded by a
microprocessor. The TSOP852.. is compatible with all
common IR remote control data formats. The TSOP854.. is
optimized to suppress almost all spurious pulses from
energy saving fluorescent lamps but will also suppress some
data signals.
This component has not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP852.., TSOP854 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 TSOP852.., TSOP854
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
• Strongly or weakly modulated noise from fluorescent
lamps with electronic ballasts (see figure 13 or figure 14)
