data stream. This gap time should have at least same

length as the burst.

• Up to 1400 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, R-2000 Code, Sony Format

(SIRCS).

When a disturbance signal is applied to the

TSOP17..KA1 it can still receive the data signal. How-

ever the sensitivity is reduced to that level that no

unexpected pulses will occure.

Some examples for such disturbance signals which

are suppressed by the TSOP17..KA1 are:

• DC light (e.g. from tungsten bulb or sunlight)

• Continuous signal at 38 kHz or at any other fre-

quency

• Signals from fluorescent lamps with electronic bal-

last (an example of the signal modulation is in the fig-

ure below).
