Product specification
TEA5767HL
1 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
• 3-wire bus
• 7-bit IF counter output via the 3-wire bus
• 4-bit level information output via the 3-wire 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
3-wire 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 TEA5767HL 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.
