TEA5767 single-chip FM stereo radio.
----------------------------------------------------------------------------
* High sensitivity due to integrated low-noise RF input amplifier
* FM mixer for conversion to IF of the US/Europe (87.5 MHz to 108 MHz) and Japanese
 (76 MHz to 91 MHz) FM band
* Preset tuning to receive Japanese TV audio up to 108 MHz
* RF Automatic Gain Control (AGC) circuit
* LC tuner oscillator operating with low cost fixed chip inductors
* FM IF selectivity performed internally
* No external discriminator needed due to fully integrated FM demodulator
* Crystal reference frequency oscillator; the oscillator operates with a 32.768 kHz clock
   crystal or with a 13 MHz crystal and with an externally applied 6.5 MHz reference
   frequency
* Phase-locked loop (PLL) synthesizer tuning system
* I2C-bus and 3-wire bus, selectable via pin BUSMODE
* 7-bit IF counter output via the bus
* 4-bit level information output via the bus
* Soft mute
* Signal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)]
* Signal dependent High Cut Control (HCC)
* Soft mute, SNC and HCC can be switched off via the bus
* Adjustment-free stereo decoder
* Autonomous search tuning function
* Standby mode
* Two software programmable ports
* Bus enable line to switch the bus input and output lines into 3-state mode

<p>SEND ME HEX FILE at </p><p>tyalonsteam@gmail.com</p>
<p>what is the freq of Oscillator ?</p>
<p>Hi can I get the code of this project</p>
Hello. I dont know about programming and microcontroller yet.<br>but i wish to make a very small FM receiver (88 MHz to 108MHz).<br>i need some help from you peoples. <br>I have some experience in electronic.<br>so please tell me if i can make this module to work without a programming block.<br>what is the purpose of the microcontroller here?
<p>Please give link the source code . As i do want to try it out with avr miccrocontrollers also</p>
<p>Hey can you port this code to small pic micro controller ( say <br>PIC16F688 ) and provide the hex file, because 16f877 is too big for this</p>
<p>please .. I need a source code</p>
<p>Nice! Is the source code available? Thanks.</p>
<p>I don't know if you'll answer this but I wanted to know what each button did on the schematic. Also, how do you stop the auto tuning once it starts and how do you manually tune?.. It seems to not be able to for me. Other than that it works pretty good. </p>
<p>thank you for the interest.<br><br>* the whole operation performed by 4 buttons.<br>[channel search,save,auto tune,stop..]<br><br>* the auto tune function with stop is defined by manual tuning with minimal stepping.</p>
<p>I figured the buttons out last night after I rewired a few things and now know what they do yet when I select &quot;Auto&quot; tune it runs until it finds a station but I cannot for the life of me get it to stop once it is started. I did figure out how to manual tune however. Also, might be me, but can Stereo/Mono be selected?.. If so how?.. Cause I am only receiving Mono.</p>
<p>there is no a selection switch for stereo/mono . it just show the audio reception status.<br></p>
Hi! Nice project! do you have to hook up speakers for this ? <br> <br>thank you! <br>marC:)
