TEA5762
Datasheet
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.
The new tuning concept combines the advantages of hand tuning with electronic facilities and features. User ?intelligence? is incorporated into the tuning algorithm and an improvement of the analog signal processing is used for the AFC function.
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.
