TEA5767 radio module radio module
The frequency range is from 76-108MHZ automatic digital tuning. High sensitivity, high stability, low noise, radio module.
A piece of low-power electronically tuned FM stereo radio circuit, which integrates IF frequency selection and demodulation network,
It can be completely free of adjustment.
High sensitivity (using low noise RF input amplifier)
Frequency range from 76-108MHZ
High amplifier automatic gain control (AGC) circuit
Low-cost fixed chip for LC tuning oscillation
FM IF selection is done internally, IF is free of tuning
PLL tuning system
Soft mute, stereo noise cancellation (SNC), high-level cutting (HCC) can be turned off via the bus
Power supply: 5V
Circuit board size: 31 X 30 MM
With power reverse protection diode
Power output filter inductor on board
Multiple capacitor combination filtering
Blue power indicator
Antenna port that can be plugged in directly
I2C bus communication
FM dedicated chip module TEA5767
The board uses the headphone amplifier chip TDA1308 as audio amplifier
The onboard 3.5MM audio interface can be directly connected to earphones and amplifiers.
To communicate with the single-chip microcomputer, only need to connect the power ground and two I2C communication lines.
The back of the circuit board is marked with I2C interface definition, power interface definition, audio output, antenna interface.
