Introduction: FM Radio Using TEA5767 and PIC16F877A Micro-controller

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

what is the freq of Oscillator ?

Hi can I get the code of this project

Hello. I dont know about programming and microcontroller yet.
but i wish to make a very small FM receiver (88 MHz to 108MHz).
i need some help from you peoples.
I have some experience in electronic.
so please tell me if i can make this module to work without a programming block.
what is the purpose of the microcontroller here?

Please give link the source code . As i do want to try it out with avr miccrocontrollers also

Hey can you port this code to small pic micro controller ( say
PIC16F688 ) and provide the hex file, because 16f877 is too big for this

Nice! Is the source code available? Thanks.
