Description



Features:

· High sensitivity due to integrated low-noise RF input amplifier
· FM mixer for conversion to IF of the US/Europe
    (87.5 to 108 MHz) and Japanese (76 to 91MHz) 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 and 3-wire bus, selectable via pin BUSMODE
· 7-bit IF counter output via the bus
· 4-bit level information output via the 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 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
· Automotive temperature range (at VCCA, VCC(VCO) and VCCD = 5 V).


Application

The IC can be switched into a low current standby mode with the standby bit; the bus is then still active. The standby current can be reduced by deactivating the bus interface (pin BUSENABLE LOW). If the bus interface is deactivated (pin BUSENABLE LOW) without the standby mode being programmed, the IC maintains normal operation, but is isolated from the bus lines.

The software programmable output (SWPORT1) can be programmed to operate as a tuning indicator output. As long as the IC has not completed a tuning action, pin SWPORT1 remains LOW. The pin becomes HIGH, when a preset or search tuning is completed or when a band limit is reached.

Description

The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage application 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.
