General description
The TEA5777 is a BiCMOS single-chip (32-pin or 48-pin package), electronically tuned
AM/FM stereo radio circuit, with fully integrated IF selectivity and demodulation including
local synthesized oscillator, and is intended to be used in electronically tuned radio sets.
In FM mode the radio is completely alignment free and in AM mode only a minimum of
antenna input alignment is required. The radio requires a minimum number of small and
low cost external components.
The IC communicates with a microcontroller via the I2C-bus or the 3-wire bus.

Features
2.1 General
I High integration level of the AM and FM receiver means a very limited number of
external components are required
I On-board PLL synthesizer tuning function which includes VCOs, dividers, phase
detectors and charge pump
I FM mixer conversion for US and Europe, OIRT and Japanese band to IF
I Crystal reference frequency oscillator operating at 4 MHz
I External reference input frequency of 13 MHz (bus selectable)
I Autonomous search function
I IF counter with 1-bit output via the bus
I Silent readout of mono or stereo information and IF in-window indication
I Level detector with 4-bit level information output via the bus
I I2C-bus or 3-wire bus
I Standby mode switched via the bus
I 2 software programmable I/O ports with multiple functions
I Supply voltage range: 2.7 V to 7 V (typical 3 V)
I Low current consumption: 9.8 mA in AM mode and 13.9 mA in FM mode
2.2 AM
I Fully integrated AM RF tuning function (no external varicap required)
I High-impedance MOSFET input
I Fully integrated AM IF lters
I Fully integrated AM VCO
I Integrated image rejection mixer structure
I LW and MW reception possibility
