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
I High sensitivity due to integrated low-noise RF input amplifier I 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 I Preset tuning to receive Japanese TV audio up to 108 MHz I RF Automatic Gain Control (AGC) circuit I LC tuner oscillator operating with low cost fixed chip inductors I FM IF selectivity performed internally I No external discriminator needed due to fully integrated FM demodulator I 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 I Phase-locked loop (PLL) synthesizer tuning system I I2C-bus and 3-wire bus, selectable via pin BUSMODE I 7-bit IF counter output via the bus I 4-bit level information output via the bus I Soft mute I Signal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)] I Signal dependent High Cut Control (HCC) I Soft mute, SNC and HCC can be switched off via the bus I Adjustment-free stereo decoder I Autonomous search tuning function I Standby mode I Two software programmable ports I Bus enable line to switch the bus input and output lines into 3-state mode
