INTEGRATED CIRCUITS DATA SHEET TEA5762 Self Tuned Radio (STR) Product specification Supersedes data of 1995 Jun 23 File under Integrated Circuits, IC01 1999 Aug 04 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 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 ORDERING INFORMATION TYPE NUMBER TEA5762H PACKAGE NAME QFP44 DESCRIPTION plasti...
