Self Tuned Radio (STR)
TEA5757; TEA5759
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
Thelocal(internal)controllerfunctionfacilitatesreduced
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
Therewillbenoapplicationconsiderationsforthetuning
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, 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
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)
High input sensitivity
Low output distortion
Due to the new tuning concept, the tuning is
independent of the channel spacing.
GENERAL DESCRIPTION
The TEA5757; TEA5759 is a 44-pin integrated AM/FM
stereo radio circuit including a novel tuning concept.
The radio part is based on the TEA5712.
The TEA5757 is used in FM-standards in which the local
oscillator frequency is above the radio frequency
(e.g. European and American standards).
The TEA5759 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
