Information as of 2000-08-20
TEA5757HL; TEA5759HL; Self Tuned Radio (STR)
The TEA5757HL; TEA5759HL is a 48-pin integrated AM/FM stereo radio circuit including a novel tuning concept. The radio part is based
on the TEA5712.
The TEA5757HL is used in FM-standards in which the local oscillator frequency is above the radio frequency (e.g. european and american
standards).
The TEA5759HL is the version in which the oscillator frequency is below the radio frequency (e.g. Japanese standard).
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.
l
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
l
The tuning quality is superior and requires no IF-counter for stop-detection; it is insensitive to ceramic filter tolerances
l
In combination with the microcontroller, fast, low-power operation of preset mode, manual-search, auto-search and auto-store are
possible
l
The local (internal) controller function facilitates reduced and simplified microcontroller software
l
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)
l
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
l
The inherent FUZZY LOGIC behaviour of the Self Tuned Radio (STR), which mimics hand tuning and yields a potentially fast yet
reliable tuning operation
l
The level of the incoming signal at which the radio must lock is software programmable
