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 TSOP348.., TSOP322.. are
compatible with all common IR remote control data formats.
The TSOP324.., TSOP344.. are 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
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
• Strongly or weakly modulated noise from fluorescent
lamps with electronic ballasts (see figure 14 or figure 15) Fig. 14 - IR Signal from Fluorescent Lamp
with Low Modulation
Fig. 15 - IR Signal from Fluorescent Lamp
with High Modulation
