TSH512

HiFi stereo/mono infrared transmitter

Stereo sub-carrier generator

s Supply voltage: 2.3V to 5.5V

s Carriers frequency range: 0.4 to 11 MHz

s High versatility: I/O pins for each section

s Two FM transmitters for stereo

s Sinusoidal carriers for high spectral purity

s Micro or line level preamplifiers with ALC

s VOX function to save on battery power

s Transmitter 2 Standby for mono operation

DESCRIPTION

The TSH512 is a 0.4 to 11 MHz dual FM transmit-

ter. Access pins to each section give a high versa-

tility and allow several applications: stereo head-

phone, multimedia headset, audio sub-carrier

generator.

The TSH512 integrates in one chip:

Low-noise audio preamplifiers with ALC (Automat-

ic Level Control), frequency modulated oscillators,

and linear output buffers to drive external transis-

tors. The sinusoidal carriers facilitates the filtering

and allows high performance audio transmission.

The VOX (Voice Operated Transmit) circuitry dis-

ables the output buffer when there is no audio to

save battery power.

For MONO applications, the STAND-BY pin en-

ables one transmitter only, reducing the supply

current.

The TSH512 forms a chipset with the dual receiv-

er TSH511.

APPLICATIONS

s Infrared HiFi stereo transmitter

s Infrared Headsets

s Stereo sub-carrier for video transmitters

s Voice operated wireless webcams

s FM IF transmit systems
