■ Stereo sub-carriers for video transmitters
■ Voice-operated wireless webcams
■ FM IF transmit systems
Description
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 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.
The TSH512 forms a chipset with the dual
receiver TSH511.
