VCO  
The TSH512 is a 0.4- to 11-MHz dual FM  
transmitter. Access pins to each section give high  
versatility and allow for several different  
applications: stereo headphone, multimedia  
headset, audio sub-carrier generator.

The TSH512 forms a chipset with the dual  
receiver TSH511.  
The TSH512 integrates in a single chip low-noise  
audio preamplifiers with ALC (automatic level  
control), frequency-modulated oscillators, and  
linear output buffers to drive the external  
transistors. The sinusoidal carriers facilitate the  
filtering and allow high performance audio  
transmission.  
The VOX (voice operated transmit) circuitry  
disables the output buffer when there is no audio  
signal to save battery power. For MONO  
applications, the STANDBY pin enables one  
transmitter only, reducing the supply current.
