Manufacturer
NXP Semiconductors
Datasheet
1. General description
2. Features
2.1 General
2.2 AM
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 I
