Product data sheet
1. General description
The TEA5764UK is a single chip electronically tuned FM stereo radio with Radio Data
System (RDS) and Radio Broadcast Data System (RBDS) demodulator and RDS/RBDS
decoder for portable 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 tune to the European, US and Japanese FM bands. It has a low power
consumption and can operate at a low supply voltage.
2. Features
s Chip scale package
s High sensitivity due to integrated low noise RF input amplifier
s FM mixer for conversion of the US/Europe (87.5 MHz to 108 MHz) and Japanese FM
band (76 MHz to 90 MHz) to IF
s Preset tuning to receive Japanese TV audio up to 108 MHz
s Auto search tuning, raster 100 kHz
s RF automatic gain control circuit
s LC tuner oscillator operating with low cost fixed chip inductors
s Fully integrated FM IF selectivity
s Fully integrated FM demodulator; no external discriminator
s Crystal oscillator at 32768 Hz, or external reference frequency at 32768 Hz
s PLL synthesizer tuning system
s IF counter; 7-bit output via the I2C-bus
s Level detector; 4-bit level information output via the I2C-bus
s Soft mute: signal dependent mute function
s Mono/stereo blend: gradual change from mono to stereo, depending on signal
s Adjustment-free stereo decoder
s Autonomous search tuning function
s Standby mode
s MPX output
s One software programmable port
s Fully integrated RDS/RBDS demodulator in accordance with EN50067
s RDS/RBDS decoder with memory for two RDS data blocks provides block
synchronization and error correction; block data and status information are available
via the I2C-bus
s Audio pause detector
