TSH511
APPLICATION SCHEMATIC
The infrared carriers are detected by the photodiode and the signal is directly amplified by the TSH511.
Optional reject filters can be added in each channel to improve crosstalk performances. Each receiver has
a standard bandpass filter (filters F1 & F3) to select the 2.3 and 2.8 MHz carriers. After the FM
demodulators, the potentiometers P1 and P2 control the volume levels. The stereo headphones are
directly connected to the integrated audio buffers. The potentiometer P3 allows adjustment of the
sensitivity of the Squelch. The Squelch function fade-in and fade-out the audio signal depending on the
level of the 2.8 MHz carrier.
