3.5.6 Function introduction to TEA5767HN
1. Description
The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage application 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.
2. Features
◆
High sensitivity due to integrated low-noise RF input amplifier
◆
FM mixer for conversion to IF of the US/Europe (87.5 to 108 MHz) and Japanese (76 to 91MHz)
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
