1 / 31 page  May 2009 Doc ID 8120 Rev 7 1/31 31 TSH512 Hi-fi stereo/mono infrared transmitter and stereo sub-carrier generator Features ■ Supply voltage: 2.3 to 5.5 V ■ Carrier frequency range: 0.4 to 11 MHz ■ High versatility: I/O pins for each section ■ Two FM transmitters for stereo ■ Sinusoidal carriers for high spectral purity ■ Micro- or line-level preamplifiers with ALC ■ VOX function to save on battery power ■ Transmitter TX2 standby for mono operation Applications ■ Infrared hi-fi stereo transmitters ■ Infrared headsets ■ 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. 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 1 + -+ - TSH512 Monostable ALC ALC VCO VCO Output buffer Output buffer TX1 TX2 LNA LNA VOX - + PEA PEA 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 1 --+ - + - TSH512 Monostable ALC ALC VCO VCO Output buffer Output buffer TX1 TX2 LNA LNA VOX - + PEA PEA Pin connections (top view) F TQFP44 10 x 10 mm www.st.com |
