7.1.2 PLL
Fast synthesizer PLL tuning system with local control for inaudible RDS updating.
7.1.3 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 and FM mixer 2
Reference frequency for the IF counter
Timing signal for the RDS update algorithm
Reference frequency (75.368 kHz) for the TEA688x (Car Audio Signal Processor CASP) or TEF689x (Car Radio Integrated Signal Processor - CRISP)
7.2 DAA
To reduce the number of manual alignments in production the following I2C-bus controlled
Digital Auto Alignment (DAA) functions are included:
• FM RF DAA
– 7-bit DAA circuitry for the conversion of the VCO tuning voltage to a controlled
alignment voltage for the FM antenna tank circuit
• FM and AM level DAA
– Level DAA circuitry for alignment of slope (3-bit) and starting point (5-bit) of the
level curve
• IF2 center DAA
– Center frequency alignment (7-bit) of integrated FM IF2 dynamic selectivity
7.3 FM signal channel
7.3.1 FM mixer 1
FM quadrature mixer converts FM RF (65 MHz to 108 MHz and weather band) 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 MHz to 107.9 MHz
US weather FM = 162.4 MHz to 162.55 MHz
Europe FM = 87.5 MHz to 108 MHz
Japan FM = 76 MHz to 91 MHz
East Europe FM = 65 MHz to 74 MHz
7.3.2 Buffer output for weather band flag (pin WBFLAG)
The buffer output on pin WBFLAG is HIGH for weather band mode.

7.3.3 FM keyed AGC
The AGC threshold is programmable and the keyed AGC function is switchable via the
I2C-bus. AGC detection occurs at the input of the first FM mixer. If the keyed AGC function
is activated, the AGC is keyed only by the narrow band level. The AGC PIN diode drive
can be activated via the I2C-bus as a local function for search tuning. The AGC sources a
constant 10 mA current into the FM PIN diode in AM mode.
7.3.4 FM IF amplifier
The FM IF amplifier provides 18 dB amplification with high linearity over a wide dynamic
range.
7.3.5 FM mixer 2
The FM mixer 2 converts 10.7 MHz FM IF1 to 450 kHz FM IF2 in I and Q phase to
achieve image rejection in the demodulator.
7.3.6 FM IF2 dynamic selectivity
The IF bandwidth of the FM IF2 is automatically adjusted depending on modulation and
reception conditions. The center frequency of the selectivity is adjusted by a 7-bit
instruction via the I2C-bus. The dynamic selectivity mode and three fixed bandwidths
(60 kHz, 90 kHz and 130 kHz) can be selected via the I2C-bus. The IF2 bandwidth is set
to 13 kHz in weather band mode.
7.3.7 FM quadrature demodulator
The FM quadrature demodulator is adjustment free.
7.3.8 Adjacent channel detector and threshold extension
In the event of breakthrough of a strong neighboring transmitter, the IF2 bandwidth is
reduced dynamically. At low RF input voltages and low modulation levels the IF2
bandwidth is reduced to achieve improved sensitivity by demodulator threshold extension.
7.3.9 Bandwidth control ‘active’ flag (pin IFBWFLAG)
Flag output IFBW = 1 from pin IFBWFLAG indicates that the IF2 bandwidth is reduced.
7.3.10 Bandwidth control monitor voltage (pin VIFBW)
The actual bandwidth is indicated by a voltage at pin VIFBW that is proportional, not linear,
to the IF bandwidth.
7.4 AM signal channel
7.4.1 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.

New in car entertainment car radio tuner IC (NICE-PACS)
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 kHz to 288 kHz
• MW = 530 kHz to 1 710 kHz (US AM band)
• SW = 5.73 MHz to 9.99 MHz (including the 31 m, 41 m and 49 m bands)
7.4.2 AM RF AGC
The AM wideband AGC in front of the first AM mixer is realized first by a cascaded NPN
transistor, which controls the transconductance of the RF amplifier JFET with 10 dB of
AGC range. Second, an AM PIN diode stage with antenna type and frequency dependent
AGC range is available. The minimum JFET drain source voltage is controlled by a DC
feedback loop (pin VAMCASFB) in order to limit the cascode AGC range to 10 dB. If the
cascode AGC is not required, a simple RF AGC loop is possible by using only a PIN
diode. In this event pins VAMCASFB and VAMCAS have to be open-circuit. In FM mode,
the cascade switches off the JFET bias current to reduce total power consumption. The
PIN diode is biased by 1 mA in FM mode.
The AGC detection points for AM AGC are at the first AM mixer input (threshold
programmable via the I2C-bus) and the IF2 AGC input (fixed threshold).
7.4.3 AM detector
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. Soft mute function is controlled
by the I2C-bus in AM mono mode.
7.4.4 AM noise 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.
Trigger sensitivity can be modified by adding an external resistor at pin AMNBHOLD.
7.5 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.
7.6 IF2 filter gain alignment
The 4-bit filter gain alignment reduces the change in IF filter gain spread when the
bandwidth is changed in dynamic mode from 155 kHz (maximum) to 25 kHz (minimum).
A frequency has to be chosen in the middle of European/US FM band, Japan band or
OIRT band (for East Europe) and the IC has to be set into dynamic bandwidth mode (IF2

Setting and clearing the FMBW bit continuously allows the adjustment of the gain
alignment to minimum change in AM/FM DC level.

7.7 Frequency offset detector/alignment
A very strong undesired neighboring signal causes offset in the demodulator in case of a
weak desired input signal.
The frequency offset detector reduces the bandwidth of the IF2 filter when the detected
offset in the demodulator is too large.
There are four bits available for frequency offset detector alignment. Every band has to be
aligned separately. Tuning has to be set to middle of the band, input signal unmodulated,
bit IFBW = 1 (alignment voltage will be given to pin IFBWFLAG). The DC voltage at
pin IFBWFLAG has to be aligned to the minimum value.

8.11 I2C-bus specification
Information about the I2C-bus can be found in the user manual UM10204 “I2C-bus
specification and user manual”.
The standard I2C-bus specification is expanded by the following definitions.
IC addresses:
• 1st IC address C2H: 1100 001R/W
• 2nd IC address C0H: 1100 000R/W
Structure of the I2C-bus logic: slave transceiver with auto increment.
Subaddresses are not used.
A second I2C-bus address can be selected by connecting pin FREF via a 68 kΩ resistor to
GND.
8.11.1 Data transfer
Data sequence: address, byte 0, 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
TEA6848HL.
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
8.11.2 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.
8.11.3 Restriction of the I2C-bus characteristic
At −40 °C the start of the acknowledge bit after transmitting the slave address exceeds the
general requirement of tHD;DAT < 3.45 μs. The start of acknowledge is tST;ACK < 4.1 μs over
the full temperature range from −40 °C to +85 °C. This will not influence the overall
system performance, because the required set-up time tSU;DAT > 250 ns is fulfilled at any
condition.

8.11.4 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
8.11.5 Default settings
No default settings at power-on reset. One I2C-bus transmission is required to program
the IC.

To avoid damage 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 interference
cannot pull down the 8.5 V supply below the 5 V supply. In case that such precautions cannot be assured under all conditions, the
maximum allowable time at which the 5 V supply may exceed the 8.5 V supply is 1 ms. The maximum allowable voltage difference in
that case is 3 V.

18. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
18.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
18.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering
18.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

18.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 15) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 39 and 40
Table 39.

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 15.
