TEA5762
Overview
- 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
