TEA5759HL

INTEGRATED CIRCUITS DATA SHEET TEA5757HL; TEA5759HL Self Tuned Radio (STR) Product specification File under Integrated Circuits, IC01 2000 Feb 02 Philips Semiconductors Product specification Self Tuned Radio (STR) 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 (radio and tuning synthesizer on one chip) means fewer external components with regard to the communication between the radio and the microcontroller (90% less components compared to the digital tuning application of a radio IC with external PLL tuning function) and a simple and small Printed-Circuit Board (PCB) There will be no application considerations for the tuning system, with regards to quality and high integration level, since there will be no external 110 MHz buffers, loop filter or false lock elimination The inherent FUZZY LOGIC behaviour of the Self Tuned Radio (STR), which mimics hand tuning and yields a potentially fast yet reliable tuning...
