FUNCTIONAL DESCRIPTION
FM mixer 1
FM quadrature mixer converts FM RF (65 to 162.55 MHz)
to an IF of 10.7 MHz. The FM mixer provides inherent
image rejection and high RF sensitivity.
FM IF amplifiers
The two FM IF amplifiers provide 10 dB and 4 dB
amplification with high linearity and dynamic range.
It is capable of tuning the US FM, US weather, Europe FM,
Japan FM and East Europe FM bands.
FM demodulator
• US FM = 87.9 to 107.9 MHz
The FM quadrature demodulator includes automatic
centre frequency adjustment and THD compensation.
• US weather = 162.4 to 162.55 MHz
• Europe FM = 87.5 to 108 MHz
AM tuner
• Japan FM = 76.0 to 91 MHz
• East Europe FM = 65.8 to 74 MHz.
The AM tuner is realized in a double conversion technique
and is capable of selecting LW/MW and SW bands.
VCO
AM mixer 1 converts AM RF to an IF1 of 10.7 MHz, while
AM mixer 2 converts 10.7 MHz IF1 to 450 kHz IF2.
The L and C tuned VCO provides the Local Oscillator (LO)
signal for both FM and AM mixer 1. It has a frequency
range of 151.2 to 248.2 MHz.
• LW = 144 to 288 kHz
• MW = 530 to 1710 kHz (US AM band)
Crystal oscillator
• SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and
49 m bands).
The crystal oscillator provides a 20.5 MHz signal that is
used for:
AM RF and IF2 AGC
• Reference frequency for frequency synthesizer PLL
The AM RF includes a pin diode drive circuit.
The threshold detection points for AM AGC are performed
at AM mixer 1 and AM IF2. AGC thresholds are
programmable via the I2C-bus.
• LO for 2nd AM mixer
• Reference frequency for the IF counter
• Timing signal for the RDS update algorithm
• Reference frequency (75.4 kHz) for the TEA6880H.
AM detector
PLL
The AM detector provides AM level information and AM AF
or AM IF2.
Fast synthesizer PLL tuning system with local control for
inaudible RDS updating.
AM AF/IF2 SWITCH
The AM output provides either a detected AM Audio
Frequency (AF) or the corresponding AM IF2 signal.
The IF2 signal can be used for AM stereo decoder
processing.
DAA
Digital Auto Alignment circuitry (FM RF DAA) for the
conversion of the VCO tuning voltage to a controlled
alignment voltage for the FM antenna tank circuit.
AM noise blanker
FM keyed AGC
The detection point for the AM noise blanker is the output
stage of AM mixer 1, while blanking is realized at the
output of the 2nd mixer.
FM contains keyed wide-band RF AGC. AGC detection
occurs at the FM mixer. The wide-band RF signal switches
a narrow band signal (IF) from the FM IF level detector
circuitry that controls the FM RF AGC block.
Trigger sensitivity can be modified by changing the resistor
value at pin 46.
It includes an AGC pin diode drive circuit for the FM RF
AGC. The pin diode drive can be activated via the I2C-bus
as a local/distance function.

TEA6840H
The data transfer has to be in this order. The LSB = 0
indicates a WRITE operation to the TEA6840H. Bit 7 of
each byte is considered the MSB and has to be transferred
as the first bit of the byte.
I2C-BUS AND I2C-BUS CONTROLLED FUNCTIONS
I2C-bus specification
The standard I2C-bus specification is expanded by the
following definitions.
• 2nd chip address C0: 1100000 R/W.
The data becomes valid at the output of the internal
latches with the acknowledge of each byte. A STOP
condition after any byte can shorten transmission times.
Structure of the I2C-bus logic: slave transceiver with auto
increment.
When writing to the transceiver by using the STOP
condition before completion of the whole transfer:
• 1st chip address C2: 1100001 R/W
• The remaining bytes will contain the old information
Subaddresses are not used.
• If the transfer of a byte is not completed, this byte is lost
and the previous information is available.
A second I2C-bus address can be selected by connecting
pin 15 via a 68 kΩ resistor to GND.
In byte 5, 4 bits are reserved for test mode purposes.
Those can only be used when the test mode is activated
by the select pin 15.
Connecting pin 15 to VDDA1 via a 100 kΩ resistor or
feeding 50 µA into that pin switches the IC into the test
mode.
Hints: When the IC is used together with the Car Analog
Sound Processor IC (TEA6880H) and when the SCL and
SDA lines are connected via Car Analog Sound Processor
IC’s I2C-bus buffer interface, the pull-up resistors of the
tuner IC should be connected to the digital supply voltage
of the TEA6880H. Otherwise a bus pull-down can occur
switching off the tuner IC supply when the I2C-bus buffer
interface of the TEA6880H is enabled for data transfer to
the tuner IC.
TEST MODE
During test mode the digital-to-analog converters of the
level and antenna DAA functions can be sequenced by the
I2C-bus SCL line.
During test mode either the TEA6880H reference
frequency, the PLL reference frequency divider or the
programmable divider output can be switched to pin 15.
For new frequency setting, in both AM and FM mode, the
programmable divider is enabled by setting the mute bit
(data byte 3 bit 7) to logic 1.
DATA TRANSFER FOR THE TEA6840H
Data sequence:
• Address
To select an FM frequency, two I2C-bus transmissions are
necessary. First data byte 3 bit 7 = 1 and second data
byte 3 bit 7 = 0.
• Byte 1
• Byte 2
Default settings by power-on reset: To be defined.
• Byte 3
• Byte 4
• Byte 5
• Byte 6.

• 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.
