TEA5757HL; TEA5759HL
FEATURES
• High selectivity with distributed IF gain
• 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
• Soft mute
• 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
• In combination with the microcontroller, fast, low-power
operation of preset mode, manual-search, auto-search
and auto-store are possible
• Low output distortion
• Due to the new tuning concept, the tuning is
independent of the channel spacing.
• 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)
GENERAL DESCRIPTION
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).
• 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 TEA5759HL 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 and
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
• FM-on/off port to control an external FM front-end

Self Tuned Radio (STR)
TEA5757HL; TEA5759HL
FUNCTIONAL DESCRIPTION
PRESET OPERATION
The TEA5757HL; TEA5759HL is an integrated AM/FM
stereo radio circuit including digital tuning and control
functions.
In preset mode, the microcontroller has to load information
such as frequency band, frequency and mono/stereo. This
information has to be sent via the bus to the STR.
The internal algorithm controls the tuning sequence as
follows:
The radio
1. The information is loaded into a shift register, a
last-station memory and the counter.
The AM circuit incorporates a double balanced mixer, a
one-pin low-voltage oscillator (up to 30 MHz) and is
designed for distributed selectivity.
2. The Automatic Frequency Control (AFC) is switched
off.
The AM input is designed to be connected to the top of a
tuned circuit. AGC controls the IF amplification and for
large signals it lowers the input impedance of the AM
front-end.
3. The counter starts counting the frequency and the
tuning voltage is varied until the desired frequency
roughly equals the real frequency.
4. The AFC is then switched on and the counter is
switched off.
The first AM selectivity can be an IF-Tank (IFT) as well as
an IFT combined with a ceramic filter; the second one is an
IFT.
5. The real frequency is more precisely tuned to the
desired frequency.
The FM circuit incorporates a tuned RF stage, a double
balanced mixer, a one-pin oscillator and is designed for
distributed IF ceramic filters. The FM quadrature detector
uses a ceramic resonator.
After the AFC has tuned the real frequency to the desired
frequency an in-lock signal can be generated. In order to
get a reliable in-lock signal, there are two parameters
measured: the field strength and the S-curve. The field
strength indicates the strength of the station and by
looking at the S-curve the system can distinguish false
in-locks from real in-locks (false in-locks occur on the
wrong slope of the S-curve).
The TEA5757HL; TEA5759HL can also be used with an
external FM front-end circuit. The external front-end is
activated by the FM-ON/OFF signal. The AFC circuit in the
TEA5757HL; TEA5759HL provides a tuning voltage to
drive the VCO of the external FM front-end. The frequency
of the external VCO is counted in the Self Tuned Radio
(STR) tuning system.
In the event of fading or pulling the in-lock signal becomes
logic 0 and the synthesizer will be switched on again and
the algorithm will be repeated.
The PLL stereo decoder incorporates a signal dependent
stereo-blend circuit and a soft-mute circuit.
SEARCH OPERATION
During a search operation, the only action the
microcontroller has to take is: sending the desired band
plus the direction and the search sensitivity level to the
STR. The search operation is performed by the charge
pump until an in-lock signal is generated (combination of
measuring the field strength and the S-curve). The AFC
then fine tunes to the station. The frequency belonging to
the found station will be counted by the counter and written
into the last-station memory and the shift register of the
counter. At this time the frequency is available in the shift
register and can be read by the microcontroller.
The microcontroller decides whether the frequency is
within the desired frequency band. If so, this frequency can
be stored under a preset and if not, a new search action
should be started.
Tuning
The tuning concept of Self Tuned Radio (STR) is based on
FUZZY LOGIC: it mimics hand tuning (hand tuning is a
combination of coarse and fine tuning to the qualitatively
best frequency position). As a consequence the tuning
system is very fast.
The tuning algorithm, which is controlled by the sequential
circuit (see Fig.1), is completely integrated; so there are
only a few external components needed.
The bus and the microcontroller can be kept very simple.
The bus only consists of three wires (BUS-CLOCK, DATA
and WRITE-ENABLE). The microcontroller must basically
give two instructions:
• Preset operation
• Search operation.

To ensure that the search function operates correctly under all conditions the following search sequence must be applied:
• Store the current frequency in the memory
• Issue the search command
• Wait for data valid and read the new frequency
• If the new frequency is the same as the stored frequency, issue a preset step (e.g. 50 kHz) and start the search
sequence again.

see Table 4 for an explanation of the shift register bits.
If in search mode no transmitter can be found, all
frequency bits of the shift register are set to logic 0.
These three signals, together with the mono/stereo pin
(MO/ST; pin 26), communicate with the microcontroller.
The mono/stereo indicator has two functions, which are
controlled by the BUS-CLOCK, as shown in Table 3.

READING DATA
WRITING DATA
While WRITE-ENABLE is LOW data can be read by the
microcontroller. At a rising edge of the BUS-CLOCK, data
is shifted out of the register. This data is available from the
point where the BUS-CLOCK is HIGH until the next rising
edge of the BUS-CLOCK occurs (see Fig.4).
While WRITE-ENABLE is HIGH the microcontroller can
transmit data to the TEA5757HL; TEA5759HL (hard mute
is active). At a rising edge of the BUS-CLOCK, the register
shifts and accepts one bit into LSB. At clock LOW the
microcontroller writes data (see Fig.5).
To read the entire shift register 24 clock pulses are
necessary.
To write the entire shift register 25 clock pulses are
necessary.

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
SOLDERING
Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
• For packages with leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
Manual soldering
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:

Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
