FUNCTIONAL DESCRIPTION
Oscillators
If the keyed AGC function is activated, the AGC function is
keyed by the narrow band level (IF).
7.1
The AGC PIN diode drive can be set via the I2C-bus to
local function for search tuning.
7.1.1
VCO
The L and C tuned VCO provides the local oscillator signal
for both FM and AM mixer 1. It has a frequency range of
151.2 to 248.2 MHz.
7.2.4
FM IF AMPLIFIERS
The two FM IF amplifiers provide 10 dB and 8.5 dB
amplification with high linearity and dynamic range.
7.1.2
CRYSTAL OSCILLATOR
The crystal oscillator provides a 20.5 MHz signal that is
used for:
7.2.5
FM DEMODULATOR
The FM quadrature demodulator includes automatic
centre frequency adjustment and THD compensation.
• Reference frequency for frequency synthesizer PLL
• Local oscillator for AM mixer 2
7.2.6
FM MPX SOFT MUTE
• Reference frequency for the IF counter
• Timing signal for the RDS update algorithm
Muting depth and start of muting are adjustable via the
I2C-bus.
• Reference frequency (75.368 kHz) for the TEA688x (car
audio signal processor - CASP) or TEF689x (car radio
integrated signal processor - CRISP).
7.2.7
ULTRASONIC NOISE DETECTOR
This is an ultrasonic noise detector with programmable
sensitivity by external resistor. The gain of the ultrasonic
noise detector also depends of the RF level.
7.1.3
PLL
Fast synthesizer PLL tuning system with local control for
inaudible RDS updating.
Attack and decay time can be set with an external timing
capacitor. The detector has a buffered output.
7.2
FM signal channel

AM signal channel
7.2.1
DAA
7.3.1
AM TUNER
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.
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:
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.
• LW = 144 to 288 kHz
• MW = 522 to 1710 kHz (European and US AM band)
• SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and
49 m bands).
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
7.3.2
AM RF AGC AND IF2 AGC
• US weather FM = 162.4 to 162.55 MHz
• Europe FM = 87.5 to 108 MHz
• Japan FM = 76 to 91 MHz
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.
• East Europe FM = 65.8 to 74 MHz.
7.3.3
AM AF OR IF2 SWITCH
7.2.3
FM KEYED AGC
The AM output provides either a demodulated AM Audio
Frequency (AF) or the corresponding AM IF2 signal. The
IF2 signal can be used for AM stereo decoder processing.
The AGC threshold is programmable and the keyed AGC
function is switchable via the I2C-bus.

7.3.4
AM SOFT MUTE
7.5
Input for external mute
The AM detector output is either not muted or signal
strength dependent soft muted audio. The soft mute
function can be switched off via the I2C-bus.
A LOW signal at pin MUTE starts muting with 1 ms slope.
Mute is active as long as the control voltage is LOW.
A HIGH at pin MUTE stops muting with 1 ms slope.
7.3.5
AM NOISE BLANKER
7.6
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.
7.7
The test mode of the IC is activated by connecting
pin FREF through a 100 kΩ resistor to VDDA1
Test mode
Trigger sensitivity can be modified by changing the resistor
value at pin AMNBHOLD.
.
The test mode is intended for IC test during IC and radio
manufacturing.
7.4
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.
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).

12 I2C-BUS PROTOCOL
When writing to the transceiver by using the STOP
condition before completion of the whole transfer:
12.1 I2C-bus specification
• 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 I2C-BUS PULL-UP RESISTORS
A second I2C-bus address can be selected by connecting
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.
pin FREF via a 68 kΩ resistor to GND.
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.
12.1.3 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:
12.1.1 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
TEA6842H.
• 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 DEFAULT SETTINGS
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.
No default settings at power-on reset. One I2C-bus
transmission is required to program the IC.

16 SOLDERING
To overcome these problems the double-wave soldering
method was specifically developed.
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.
– 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.
16.2 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.
Driven by legislation and environmental forces the
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.
worldwide use of lead-free solder pastes is increasing.
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.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
• below 225 °C (SnPb process) or below 245 °C (Pb-free
process)
– for all BGA, HTSSON-T and SSOP-T packages
– for packages with a thickness 2.5 mm
16.4 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.
– 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.
