TSOP17XX is a commonly used IR receiver for Infrared PCM remote control systems. It is used in TVs, DVD Players, Burglar Alarms etc. This component is built with PIN Diode, Preamplifier and internal filter for PCM (Pulse Code Modulation) frequency and its epoxy package is designed as an IR filter. These are available with different carrier frequencies out of which TSOP1738 is very common whose carrier frequency is 38KHz. The output of TSOP17XX receivers can be directly connected to a microcontroller or microprocessor for further processing.
