TEA5767HN
Low-power FM stereo radio for handheld applications
Rev. 05 — 26 January 2007 Product data sheet 1. General description
The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage
applications with fully integrated Intermediate Frequency (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
n High sensitivity due to integrated low-noise RF input amplifier
n 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
n Preset tuning to receive Japanese TV audio up to 108 MHz
n RF Automatic Gain Control (AGC) circuit
n LC tuner oscillator operating with low cost fixed chip inductors
n FM IF selectivity performed internally
n No external discriminator needed due to fully integrated FM demodulator
n 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
n Phase-locked loop (PLL) synthesizer tuning system
n I2C-bus and 3-wire bus, selectable via pin BUSMODE
n 7-bit IF counter output via the bus
n 4-bit level information output via the bus …
