GENERAL DESCRIPTION
The TEA5762 is a 44-pin integrated AM-radio and FM-IF and demodulator part including a novel tuning concept. The radio part is based on the TEA5712.
It is designed for the use with an external FM front-end.

FEATURES
• The tuning system has an optimized IC partitioning both from application (omitting interferences) and flexibility (removable front panel option) point of view: the tuning synthesizer is on-chip with the radio
• The tuning quality is superior and requires no IF-counter for stop-detection; it is insensitive to ceramic filter tolerances
• In combination with the microcontroller, fast, low-power operation of preset mode, manual-search, auto-search and auto-store are possible
• The local (internal) controller function facilitates reduced and simplified microcontroller software
• The high integration level means fewer external components with regard to the communication between the radio and the microcontroller and a simple and small Printed-Circuit Board (PCB)
• The inherent FUZZY LOGIC behaviour of the Self Tuned Radio (STR), which mimics hand tuning and yields a potentially fast yet reliable tuning operation
• The level of the incoming signal at which the radio must lock is software programmable
• Two programmable ports
• FM-on/off port to control the external FM front-end
• High selectivity with distributed IF gain
• Soft mute
• Signal dependent stereo-blend
• High impedance MOSFET input on AM
• Wide supply voltage range of 2.5 to 12 V
• Low current consumption 18 mA at AM and FM (including tuning synthesizer for AM)
• Low noise figure
• Low output distortion
• Due to the new tuning concept, the tuning is independent of the channel spacing.
