IR Receiver Modules for Remote Control Systems
Description
The TSOP31#.. 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 be directly
decoded by a microprocessor. The TSOP311.. is
compatible with all common IR ... remote control data
formats. The TSOP313.. is optimized to better
suppress 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 TSOP31#.. series is 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 TSOP31#.. 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
