Sub-carrier generator application: voice-operated wireless
camera
Thanks to its operating frequency, the TSH512 offers the possibility of generating usual
audio sub-carriers for video applications (Figure 23). The camera can be voice-activated
using the VOX-MUTE output of the TSH512. The TSH512 also provides bias, amplification,
ALC for the electret microphone.

Multimedia application
4.3.1
Headset side
The TSH512 is used in mono mode to transmit the signal of the electret condenser
microphone of the headset. The circuit is supplied by batteries and the VOX function
switches off the output stages to save energy. The usual working frequency is 1.7 MHz for
infrared mono operation.
