function can be switched off via the I2C-bus.
FM KEYED AGC
The AGC threshold is programmable and the keyed AGC
function is switchable via the I2C-bus.
2003 Dec 19
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 at AM mixer 1 input via the I2C-bus.
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.

AM NOISE BLANKER
7.5
Buffer output for weather band flag
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.
In weather band mode the output is HIGH.
Trigger sensitivity can be modified by changing the resistor
value at pin AMNBHOLD.
The test mode of the IC is activated by connecting
pin FREF through a 100 kΩ resistor to VDDA1.
7.4
The test mode is intended for IC test during IC and radio
manufacturing.
7.6
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.
Test mode
In test mode the settling time of the AM IF2 AGC is
reduced to less than 100 ms in the nominal application.

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).

When writing to the transceiver by using the STOP
condition before completion of the whole transfer:
12 I2C-BUS PROTOCOL
I2C-bus specification
12.1
• The remaining bytes will contain the old information
The standard I2C-bus specification is expanded by the
following definitions.
• If the transfer of a byte is not completed, this byte is lost
and the previous information is available.
IC addresses:
In byte 5, 4 bits are reserved for test mode purposes. The
state of the test bits, if not in test mode, is don’t care.
• 1st IC address C2H: 1100001 R/W
• 2nd IC address C0H: 1100000 R/W.
12.1.2
A second I2C-bus address can be selected by connecting
pin FREF via a 68 kΩ resistor to GND.
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.
Structure of the I2C-bus logic: slave transceiver with auto
increment.
Subaddresses are not used.
Remark: The I2C-bus operates at a maximum clock rate of
100 kHz. It is not allowed to connect the IC to an I2C-bus
operating at a higher clock rate. Maximum LOW level is
1.5 V and minimum HIGH level is 3 V.
12.1.1
I2C-BUS PULL-UP RESISTORS
12.1.3
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:
DATA TRANSFER
Data sequence: address, byte 1, byte 2, byte 3, byte 4,
byte 5, byte 6 and byte 7. The data transfer has to be in
this order. The LSB = 0 indicates a WRITE operation to the
TEA6843HL.
• First: bit MUTE = 1
• Second: bit MUTE = 0.
Bit 7 of each byte is considered the MSB and has to be
transferred as the first bit of the byte.
12.1.4
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.
DEFAULT SETTINGS
No default settings at power-on reset. One I2C-bus
transmission is required to program the IC.

To overcome these problems the double-wave soldering
method was specifically developed.
16 SOLDERING
16.1
Introduction to soldering surface mount
packages
If wave soldering is used the following conditions must be
observed for optimal results:
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).
• 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):
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.
16.2
– 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.
Reflow soldering
The footprint must incorporate solder thieves at the
downstream end.
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.
Driven by legislation and environmental forces the
worldwide use of lead-free solder pastes is increasing.
• 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.
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.
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 reflow peak temperatures range from
215 to 270 °C depending on solder paste material. The
top-surface temperature of the packages should
preferably be kept:
Typical dwell time of the leads in the wave ranges from
3 to 4 seconds at 250 °C or 265 °C, depending on solder
material applied, SnPb or Pb-free respectively.
• below 225 °C (SnPb process) or below 245 °C (Pb-free
process)
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
– for all BGA, HTSSON-T and SSOP-T packages
16.4
– for packages with a thickness 2.5 mm
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.
– for packages with a thickness < 2.5 mm and a
volume ≥ 350 mm3 so called thick/large packages.
• below 240 °C (SnPb process) or below 260 °C (Pb-free
process) for packages with a thickness < 2.5 mm and a
volume < 350 mm3 so called small/thin packages.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
16.3
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.

Notes
1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a 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 transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account
be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature
exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature
must be kept as low as possible.
4. 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.
5. 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.
6. 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.
7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP 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.
8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted
on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar
soldering process. The appropriate soldering profile can be provided on request.
9. Hot bar or manual soldering is suitable for PMFP packages.
