Self Tuned Radio (STR)

TEA5757; TEA5759

FEATURES

• High selectivity with distributed IF gain

• Soft mute

• 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

• Signal dependent stereo-blend

• High impedance MOSFET input on AM

• Wide supply voltage range of 2.5 to 12 V

• The tuning quality is superior and requires no IF-counter

for stop-detection; it is insensitive to ceramic filter

tolerances

• Low current consumption 18 mA at AM and FM

(including tuning synthesizer)

• High input sensitivity

• Low output distortion

• In combination with the microcontroller, fast, low-power

operation of preset mode, manual-search, auto-search

and auto-store are possible

• Due to the new tuning concept, the tuning is

• The local (internal) controller function facilitates reduced

independent of the channel spacing.

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

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).

• 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 TEA5759 is the version in which the oscillator

frequency is below the radio frequency

(e.g. Japanese standard).

• The inherent FUZZY LOGIC behaviour of the Self

Tuned Radio (STR), which mimics hand tuning, yields a

potentially fast yet reliable tuning operation

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.

• The level of the incoming signal at which the radio must

lock is software programmable

• Two programmable ports
