TSOP48..SO1
Vishay Telefunken
Suitable Data Format
The circuit of the TSOP48..SO1 is designed in that way that unexpected output pulses due to noise or disturbance signals are avoided. A bandpassfilter, an integrator stage and an automatic gain control are used to suppress such disturbances.
The distinguishing mark between data signal and disturbance signal are carrier frequency, burst length and duty cycle.
The data signal should fullfill the following condition:
•Carrier frequency should be close to 38kHz.
•Burst length should be 10 cycles/burst or longer.
•After each burst which is between 10 cycles and 70 cycles a gap time of at least 14 cycles is necessary.
•
Some examples for suitable data format are:
NEC Code (repetitive pulse), NEC Code (repetitive data), Toshiba Micom Format, Sharp Code
When a disturbance signal is applied to the HS0038A2 it can still receive the data signal. However the sensitivity is reduced to that level that no unexpected pulses will occure.
Some examples for such disturbance signals which are suppressed by the TSOP48..SO1 are:
•DC light (e.g. from tungsten bulb or sunlight)
•Continuous signal at 38kHz or at any other frequency
•Signals from fluorescent lamps with electronic ballast with low modulation:
•Up to 800 short bursts per second can be received continuously.
