TEA5777
Datasheet
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
General
- High integration level of the AM and FM receiver means a very limited number of external components are required
- On-board PLL synthesizer tuning function which includes VCOs, dividers, phase detectors and charge pump
- FM mixer conversion for US and Europe, OIRT and Japanese band to IF
- Crystal reference frequency oscillator operating at 4 MHz
- External reference input frequency of 13 MHz (bus selectable)
- Autonomous search function
- IF counter with 1-bit output via the bus
- Silent readout of mono or stereo information and IF in-window indication
- Level detector with 4-bit level information output via the bus
- I2C-bus or 3-wire bus
- Standby mode switched via the bus
- 2 software programmable I/O ports with multiple functions
- Supply voltage range: 2.7 V to 7 V (typical 3 V)
- Low current consumption: 9.8 mA in AM mode and 13.9 mA in FM mode
AM
- Fully integrated AM RF tuning function (no external varicap required)
- High-impedance MOSFET input
- Fully integrated AM IF filters
- Fully integrated AM VCO

FM
- High input sensitivity
- Fully integrated FM IF selectivity
- Fully integrated FM demodulator (no external discriminator)
- Integrated image rejection mixer structure
- RF LC oscillator operating with low cost fixed inductors (referenced to ground)
- FM I/Q mixer for conversion of the US, Europe, Japanese and OIRT band to IF
- Fully integrated, adjustment free, stereo decoder
- Signal dependent mono or stereo blend (with on and off function)
- FM stereo readout via the bus and silent readout mode
- RDS MPX output available
- Stereo decoder can be switched off via the bus
- Integrated anti-birdy filter
