DESCRIPTION
The TSOP322.., TSOP348.., TSOP324.. and TSOP344..
series are miniaturized IR receiver modules for infrared
remote control systems. A PIN diode and a preamplifier are
assembled on lead frame, the epoxy package contains an IR
filter.
The demodulated output signal can be directly connected to
a microprocessor for decoding.
The TSOP324.., TSOP344.. series devices are optimized
to suppress almost all spurious pulses from energy saving
lamps like CFLs. The AGC4 used in the TSOP324..,
TSOP344.. may suppress some data signals. The
TSOP322.., TSOP348.. series are provided primarily for
compatibility with old AGC2 designs. New designs should
prefer the TSOP324.., TSOP344.. series containing the
newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
This series is designed to suppress spurious output pulses
due to noise or disturbance signals. The devices can
distinguish data signals from noise due to differences in
frequency, burst length, and envelope duty cycle. The data
signal should be close to the device’s band-pass center
frequency (e.g. 38 kHz) and fulfill the conditions in the table
below.
When a data signal is applied to the product in the presence
of a disturbance, the sensitivity of the receiver is
automatically reduced by the AGC to insure that no spurious
pulses are present at the receiver’s output. Some examples
which are suppressed are:
• DC light (e.g. from tungsten bulbs sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated patterns from fluorescent
lamps with electronic ballasts (see Fig. 13 or Fig. 14).
