12.19. TSOP1836

The TSOP18.. – series are miniaturized receivers for infrared remote control systems. PIN diode and

preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. Carrier frequency

for TSOP1836 is 36KHz.

The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the

reliable function even in disturbed ambient and the protection against uncontrolled output pulses.

• Photo detector and preamplifier in one package

• Internal filter for PCM frequency

• TTL and CMOS compatibility

• Output active low

• Improved shielding against electrical field disturbance

• Suitable burst length >6 cycles/burst

Special Features

• Small size package

• Enhanced immunity against all kinds of disturbance light

• No occurrence of disturbance pulses at the output

• Short settling time after power on (<200μS)

The PI5V330 is well suited for video applications when switching composite or RGB analogue. A

picture-in-picture application will be described in this brief. The pixel-rate creates video overlays so two

or more pictures can be viewed at the same time. An inexpensive NTSC titler can be implemented by

superimposing the output of a character generator on a standard composite video background.
