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:
For data formats with long bursts (more than 10 carrier cycles) please see the data sheet for TSOP312../TSOP314..
