TEA5768HL

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.

Features

• 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)
• 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.
