decoded by a microprocessor. TSOP51.. is the stan-
dard IR remote control SMD-Receiver series, sup-
porting all major transmission codes.

The distinguishing mark between data signal and dis-
turbance signal are carrier frequency, burst length
and duty cycle.
The data signal should fullfill the following condition:
• Carrier frequency should be close to center fre-
quency of the bandpass (e.g. 38kHz).
• Burst length should be 6 cycles/burst or longer.
• After each burst which is between 6 cycles and 70
cycles a gap time of at least 10 cycles is neccessary.
• For each burst which is longer than 1.8ms a corre-
sponding gap time is necessary at some time in the
data stream. This gap time should have at least same
length as the burst.
&bulllet; Up to 2200 short bursts per second can be
received continuously.
Some examples for suitable data format are: NEC
Code, Toshiba Micom Format, Sharp Code, RC5
Code, RC6 Code, RCMM Code, R-2000 Code,
RECS-80 Code.
When a disturbance signal is applied to the TSOP21..
it can still receive the data signal. However the sensi-
tivity is reduced to that level that no unexpected
pulses will occur.
Some examples for such disturbance signals which
are suppressed by the TSOP21.. are:
&bulllet; DC light (e.g. from tungsten bulb or sunlight)
&bulllet; Continuous signal at 38kHz or at any other
frequency
&bulllet; Signals from fluorescent lamps with elec-
tronic ballast (an example of the signal modulation is
in the figure below).
