7 FUNCTIONAL DESCRIPTION

7.1 Oscillators

7.1.1 VCO
TheL and CtunedVCO provides the local oscillator signal

for both FM and AM mixer 1. It has a frequency range of

151.2 to 248.2 MHz.

7.1.2 CRYSTAL OSCILLATOR
The crystal oscillator provides a 20.5 MHz signal that is

used for:

• Reference frequency for frequency synthesizer PLL

• Local oscillator for AM mixer 2

• Reference frequency for the IF counter

• Timing signal for the RDS update algorithm

• Reference frequency (75.4 kHz) for the TEA6880H (car

audio signal processor - CASP) or TEF6890H (car radio
integrated signal processor).

7.1.3 PLL
Fast synthesizer PLL tuning system with local control for

inaudible RDS updating.

7.2 FM signal channel

7.2.1 DAA
FM RF Digital Auto Alignment (DAA) circuitry for the

conversion of the VCO tuning voltage to a controlled
alignment voltage for the FM antenna tank circuit.

7.2.2 FM I/Q MIXER
FM quadrature mixer converts FM RF (65 to 162.55 MHz)

to IF of 10.7 MHz. The FM mixer provides inherent image
rejection and high RF sensitivity.

It is capable of tuning the US FM, US weather,
Europe FM, Japan FM and East Europe FM bands:

• US FM = 87.9 to 107.9 MHz

• US weather FM = 162.4 to 162.55 MHz

• Europe FM = 87.5 to 108 MHz

• Japan FM = 76.0 to 91 MHz

• East Europe FM = 65.8 to 74 MHz.

It includes an AGC PIN diode drive circuit for the FM RF
AGC.The PIN diode drive can be activated via theI2C-bus
as a local or distance function.

The AGC threshold is programmable and the keyed AGC
function is switchable via the I2C-bus.

7.2.4 FM IF AMPLIFIERS
The two FM IF amplifiers provide 10 dB and 4 dB

amplification with high linearity and dynamic range.

7.2.5 FM DEMODULATOR
The FM quadrature demodulator includes automatic

centre frequency adjustment and THD compensation.

7.3 AM signal channel

7.3.1 AM TUNER INCLUDING MIXER 1 AND MIXER 2
The AM tuner is realized in a double conversion technique

and is capable of selecting LW, MW and SW bands.
AM mixer 1 converts AM RF to IF1 of 10.7 MHz, while

AM mixer 2 converts IF1 of 10.7 MHz to IF2 of 450 kHz:

• LW = 144 to 288 kHz

• MW = 530 to 1710 kHz (US AM band)

• SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and

49 m bands).

7.3.2 AM RF AGC AND IF2 AGC
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.

7.3.3 AM DETECTOR
The AM detector provides AM level information and

AM AF or AM IF2.

7.3.4 AM AF OR IF2 SWITCH
The AM output provides either a detected AM AF or the

corresponding AM IF2 signal. The IF2 signal can be used
for AM stereo decoder processing.

7.2.3 FM KEYED AGC
FM contains keyed wide-band RF AGC. AGC detection

occursattheFM mixer. The wide-bandRF signalswitches
a narrow band signal (IF) from the FM IF level detector
circuitry that controls the FM RF AGC block.

12 I2C-BUS PROTOCOL

2

12.1 I

C-bus specification

The standard I2C-bus specification is expanded by the
following definitions.

IC addresses:

• 1st IC address C2: 1100001

• 2nd IC address C0: 1100000.

2

Structure of the I

C-bus logic: slave transceiver with auto

increment.
Subaddresses are not used.

12.1.1 TEST MODE

Connecting pin f

ref

to V

via a 100 kΩ resistor or

DDA1

feeding 50 µA into that pin switches the IC into the test
mode.

During test mode the digital-to-analog converters of the
levelandantenna DAA functions can be sequenced by the
I2C-bus SCL line.

During test mode either the TEA6880H or TEF6890H
reference frequency, the PLL reference frequency divider
or the programmable divider output can be switched to
pin f

.

ref

12.1.3 I2C-bus pULL-UP RESISTORS
When the IC is used together with the TEA6880H or

TEF6890HandbothSCLandSDAlinesareconnectedvia
the I2C-bus to the CASP, the pull-up resistors of the
tuner IC should be connected to the digital supply voltage
of the TEA6880H or TEF6890H. Otherwise a I2C-bus
pull-downcanoccurswitchingoffthetuner IC supply when
the I2C-bus buffer interface of the TEA6880H or
TEF6890H is enabled for data transfer to the tuner IC.

12.1.4 FREQUENCY SETTING
For new frequency setting, in both AM and FM mode, the

programmable divider is enabled by setting bit MUTE =1.
To select an FM frequency, two I2C-bus transmissions are
necessary:

• First: bit MUTE = 1

• Second: bit MUTE = 0.

12.1.2 DATA TRANSFER FOR THE TEA6840H

Data sequence: address, byte 1, byte 2, byte 3, byte 4,
byte 5, and byte 6.

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.

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.

When writing to the transceiver by using the STOP
condition before completion of the whole transfer:

• The remaining bytes will contain the old information

• If the transfer of a byte is not completed, this byte is lost

and the previous information is available.

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 f

15 SOLDERING

15.1 Introduction to soldering surface mount packages

Thistextgivesaverybriefinsighttoacomplextechnology.
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).
There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for
certainsurfacemountICs,butitisnotsuitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.

15.2 Reflow soldering

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
totheprinted-circuitboardby screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.

Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.

15.3 Wave soldering

Conventional single wave soldering is not recommended
forsurfacemountdevices(SMDs)orprinted-circuitboards
with a high component density, as solder bridging and
non-wetting can present major problems.

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:

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

• 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;

– 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.

• Forpackageswithleadsonfoursides,thefootprint 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.

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.

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.

15.4 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.

When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

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.
