- General description
The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage
applications with fully integrated IF selectivity and demodulation. The radio is completely
adjustment-free and only requires a minimum of small and low cost external components.
The radio can be tuned to the European, US and Japanese FM bands.
- Features
- 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
