1 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 ( 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 kHz clock crystal or with a 13 MHz crystal and with an externally applied MHz reference frequency n Phase-locked loop (PLL) synthesizer tuning system n I2C-bus and 3-wire bus, selectable via pin BUSMODE.

2 N 7-bit IF counter output via the bus n 4-bit level information output via the bus n Soft mute n Signal dependent mono to stereo blend [ stereo Noise Cancelling (SNC)]. n Signal dependent High Cut Control (HCC). n Soft mute, SNC and HCC can be switched off via the bus n Adjustment-free stereo decoder n Autonomous search tuning function n Standby mode n Two software programmable ports n Bus enable line to switch the bus input and output lines into 3-state mode NXP Semiconductors TEA5767HN .

Functional description Low-noise RF amplifier The Low Noise Amplifier (LNA) input impedance together with the LC RF input circuit defines an FM band filter. The gain of the LNA is controlled by the RF AGC circuit. FM mixer The FM quadrature mixer converts the FM RF (76 MHz to 108 MHz) to an IF of 225 kHz. VCO. The varactor tuned LC VCO provides the Local Oscillator (LO) signal for the FM. quadrature mixer. The VCO frequency range is 150 MHz to 217 MHz. TEA5767HN_5 NXP 2007.
