7 FUNCTIONAL DESCRIPTION
7.1 Oscillators
7.1.1 VCO
TheL and Ctuned VCO provides thelocal 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 TEA688x (car
audio signal processor - CASP) or TEF689x (car radio
integrated signal processor - CRISP).
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.
7.2.3 FM KEYED AGC
FM contains keyed wide-band RF AGC. AGC detection
occursattheFM mixer.Thewide-bandRF signalswitches
a narrow band signal (IF) from the FM IF level detector
circuitry that controls the FM RF AGC block.
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 1AND 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.

7.3.5 AM NOISE DETECTOR AND BLANKER
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 mixer 2.
Triggersensitivity canbemodifiedbychanging theresistor
value at pin AMNBHOLD.
7.3.6 FM AND AM LEVEL DETECTOR
FM and AM level detectors provide the temperature
compensated output voltage. The starting points and
slopes of the level detector outputs are programmable via
the I2C-bus.
7.4 Test mode
The test mode of the IC is activated by:
•Sending the test byte (byte 5) to the IC
•Connecting pin FREF through a 100 kΩ resistor to
VDDA1
•Applying 50 µA to pin FREF.
If the test mode is enabled by pin FREF:
•The settling time of the AM IF2 AGC is reduced to less
than 100 ms in the nominal application
•The digital-to-analog converters for the antenna DAA
and the level DAA can be clocked directly by the SCL
line of the I2C-bus
•The output at pin FREF can be selected by the I2C-bus:
TEA688x or TEF689x reference frequency, PLL
reference frequency or PLL programmable divider
output frequency
•The RDS update control circuit can be clocked directly
via pin DAATD
•Pin T1AMAGC can be used to enable the load PLL
circuit of the RDS update control circuit
•Charge pumps can be set into 3-state mode.
8 LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
Notes
1. To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any
5 V supply voltage. This is also necessary during power-on and power-down sequences. Precautions have to be
provided in such a way that interferences can not pull down the 8.5 V supply below the 5 V supply.
2. Machine model (R = 0 Ω, C = 200 pF).
3. Human body model (R = 1.5 kΩ, C = 100 pF).

12 I2C-BUS PROTOCOL
12.1 I2C-bus specification
Informationabout theI2C-buscanbefound inthebrochure
“The I
2
C-bus and how to use it”
(order number
9398 393 40011).
The standard I2C-bus specification is expanded by the
following definitions.
IC addresses:
•1st IC address C2: 1100001
•2nd IC address C0: 1100000.
Structure of the I2C-bus logic: slave transceiver with auto
increment.
Subaddresses are not used.
Exception to the standard I2C-bus specification:
•The data hold time tHD;DAT must be at least 1 µs.
12.1.1 TEST MODE
Connecting pin FREF to VDDA1 via a 100 kΩ resistor or
feeding 50 µA into that pin switches the IC into the test
mode.
During test mode the digital-to-analog converters of the
leveland antenna DAA functionscan be sequencedby the
I2C-bus SCL line.
During test mode either the TEA688x or TEF689x
reference frequency, the PLL reference frequency divider
or the programmable divider output can be switched to
pin FREF.
12.1.2 DATA TRANSFER
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
TEA6846H.
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 FREF.
12.1.3 I2C-BUS PULL-UP RESISTORS
When the IC is used together with the TEA688x or
TEF689x and both SCL and SDA lines are connected via
the I2C-bus to the TEA688x or TEF689x, the pull-up
resistors of the tuner IC should be connected to the digital
supply voltage of the TEA688x or TEF689x. Otherwise an
I2C-bus pull-down can occur switching off the tuner IC
supply when the I2C-bus buffer interface of the TEA688x
or TEF689x 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.

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
certainsurface mount ICs, but it isnotsuitableforfinepitch
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-circuit board byscreenprinting, 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
forsurface mount devices (SMDs) or printed-circuit boards
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.
•Forpackageswith leads on foursides,thefootprintmust
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.

15.5 Suitability of surface mount IC packages for wave and reflow soldering methods
Notes
1. Formoredetailed information on theBGApackagesrefer to the
“(LF)BGAApplicationNote
”(AN01026);ordera copy
from your Philips Semiconductors sales office.
2. 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”
.
3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.
4. 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.
5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
6. Wave soldering is 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.
