1 FEATURES
TEA5768HL
• High sensitivity due to integrated low-noise RF input amplifier • 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 • 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 • 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 • PLL synthesizer tuning system • I2C-bus • 7-bit IF counter output via the I2C-bus • 4-bit level information output via the I2C-bus • Soft mute • Signal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)] • Signal dependent High Cut Control (HCC) 3 ORDERING INFORMATION TYPE NUMBER TEA5768HL PACKAGE NAME LQFP32 DESCRIPTION plastic low profile quad flat package; 32 leads; body 7 × 7 × 1.4 mm VERSION SOT358-1
• Soft mute, SNC and HCC can be switched off via the I2C-bus • Adjustment-free stereo decoder • Autonomous search tuning function • Standby mode • Two software programmable ports • Bus enable line to switch the bus input and output lines into 3-state mode. 2 GENERAL DESCRIPTION
The TEA5768HL is a single-chip electronically tuned FM stereo radio for low-voltage applications 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.
