7. Functional description
7.1 FM mixer 1
The FM quadrature mixer converts FM RF (65 MHz to 108 MHz and 162.4 MHz to
162.55 MHz) to an IF of 10.7 MHz. The FM mixer provides inherent image rejection and a
large dynamic range. The image rejection can be switched from low injection LO to high
injection LO via the I2C-bus independently of the band selection. The gain can be
increased by 6 dB via the I2C-bus.
7.2 FM RF AGC
AGC detection at the FM front-end mixer input with programmable threshold. When the
threshold is exceeded, the PIN diode drive circuit sources a current to an external PIN
diode circuit, keeping the mixer input signal level constant.
Keyed AGC function is selectable via the I2C-bus and uses the in-band level information
derived from the limiter level detector.
The AGC PIN diode drive circuit can be forced via the I2C-bus to deliver a fixed current as
a local function for search tuning. In AM mode, the AGC PIN diode drive circuit can also
be forced via the I2C-bus to deliver the maximum source current into the external FM PIN
diode circuitry. AGC information is available via the I2C-bus.
7.3 FM mixer 2
The FM quadrature mixer converts 10.7 MHz FM IF1 to 450 kHz FM IF2 and includes
inherent image rejection. The gain can be selected via I2C-bus to compensate for different
ceramic filter insertion loss.

7.4 FM IF2 channel filter
The order and dynamic range of the filter is designed for operation with only one external
ceramic filter in the application. The filter characteristic is optimized to combine high
selectivity with low distortion from maximum to minimum IF bandwidth settings. The
bandwidth of the filter can be selected directly with 5 bits via the I2C-bus or automatically
via the bandwidth control algorithm. When the automatic mode is selected the bandwidth
depends on the signal conditions: the amount of adjacent channel, the deviation of the
desired signal, detuning and signal strength.
The filter center frequency is I2C-bus aligned with 6 bits.
7.5 FM limiter and level detection
The limiter amplifies the IF filter output signal, removes AM modulations from the IF signal
and supplies a well defined signal for the FM demodulator. From the limiter also the RSSI
is derived which is converted to a suitable level voltage with minimum temperature drift.
7.6 FM demodulator
The fully integrated FM demodulator converts the IF signal from the limiter to the FM MPX
output signal with very low distortion. The center frequency of the filter in the demodulator
is aligned together with the IF2 filter center frequency.
7.7 Audio output buffer
The output buffer for AM and FM amplifies the demodulated signal and includes low-pass
filtering to attenuate any IF residual signals. The gain is increased in weather band
reception to compensate for the low frequency deviation.
7.8 Tuning mute
The audio soft slope tuning mute circuit is controlled by the sequential machine for
different tuning actions to eliminate audible effects. Control signals are generated to
control the muting and the weak signal processing in the signal processor.
7.9 Weather band input
A separate RF input to the FM front-end mixer for weather band makes the weather band
application easier.
7.10 IF filter and demodulator tuning
The center frequency as well as the bandwidth of both the IF filter and demodulator are
coupled to the stable crystal reference frequency. Fine adjustment is achieved with a 6-bit
DAA.
7.11 VCO and dividers
The varactor tuned LC oscillator together with the dividers provides the local oscillator
signal for both AM and FM front-end mixers. The VCO has an operating frequency of
approximately 160 MHz to 256 MHz. In FM mode the LO frequency is divided by 1, 2 or 3.

TEF6862
Philips Semiconductors
Car Radio Enhanced Selectivity Tuner (CREST)
These dividers generate in-phase and quadrature-phase output signals used in the
FM front-end mixer for image rejection. In AM mode the LO frequency is divided by 6, 8,
10, 16 or 20 depending on the selected AM band.
7.12 Crystal oscillator
The linear crystal oscillator provides a 20.5 MHz signal. A divider-by-two generates
in-phase and quadrature-phase mixer frequencies for the conversion from IF1 to IF2
including image rejection. The reference divider generates from the crystal frequency
various reference frequencies for the tuning PLL. Also the different timing signals for the
sequential machine as well as the analog signal processor reference frequency are
derived from the crystal reference.
7.13 Tuning PLL
The tuning PLL locks the VCO frequency divided by the programmable divider ratio to the
reference frequency. Due to the combination of different charge pump signals in the
PLL loop filter, the loop parameters are adapted dynamically. Tuning to different radio
frequencies is done by changing the programmable divider ratio. The tuning step size is
selected with the reference frequency divider setting.
7.14 Antenna DAA
The antenna DAA measures the VCO tuning voltage and multiplies it with a factor defined
by the 7-bit DAA1 setting to generate a tuning voltage for the FM antenna tank circuit.
A second tuning voltage (DAA output 2) for an optional second FM tank circuit is derived
from the first tuning voltage with 4 bits.
7.15 AM RF AGC
The AM front-end is designed for the application of an external JFET low noise amplifier
with cascode AGC and PIN diode AGC both controlled by an integrated AGC circuit. Four
AGC thresholds of the detector at the first mixer input are selectable via I2C-bus. A further
detector at the IF AGC input prevents undesired overload (see Figure 21). AGC
information can be read out via I2C-bus. The PIN diode current drive circuit includes a
pull-up current source for reverse biasing of the PIN diode, when the AGC is not active to
achieve a low parasitic capacitance.
7.16 AM mixer
The large dynamic range AM mixer converts AM RF (144 kHz to 26.1 MHz) to an IF of
10.7 MHz.
7.17 AM IF noise blanker
The spike detection for the AM noise blanker is at the output of the AM front-end mixer.
Blanking is realized at the output of the second AM mixer. The sensitivity of the noise
blanker can be set in three settings and switched off via I2C-bus.

7.18 AM IF AGC amplifier and demodulator
The 450 kHz IF2 signal after the ceramic channel selection filter is amplified by the
IF AGC amplifier and demodulated. Instead of the demodulated AM audio signal, also the
IF2 signal can be selected on the MPXAM output pin. This IF2 signal can be used for an
external AM stereo decoder. To avoid overdrive of the input stage a detector at the input
drives the RF AGC.
7.19 AM level detection
The IF2 signal used for AM IF AGC and demodulation is also used in the limiter circuit for
in-band level detection to generate a level voltage.
7.20 AM and FM level DAA
The start and slope of the level detector output are programmable with 5 bits and 3 bits
respectively to achieve level information independent on gain variations in the signal
channel.
7.21 AM and FM IF counter
The output signal from the limiters is used for IF counting in both AM and FM. The
IF count time is automatically controlled to achieve the optimum counting accuracy. The
minimum count time is 2 ms.

After a tuning action, which is activated by the state machine, the IF counter is reset at
that moment when tuning is established (PLL in-lock). Reset is also possible via bit IFCR.
The first counter result is available from 2 ms after reset. For FM further results can be
obtained from 4 ms, 8 ms, 16 ms and 32 ms after reset, the increasing count time
attenuates influence of FM modulation on the counter result. After this, the counter
continues at the maximum count time of 32 ms (see Figure 5).
After AFU sampling the IF counter read value is held (IFCM = 10); see Figure 6, Figure 14
and Figure 15. The counter itself remains active in the background in raw mode (2 ms
count time). The IF counter hold is disabled after I2C-bus read.
For AM mode the count time is fixed to 2 ms and results are available every 2 ms.

8.2 Write mode
The tuner is controlled by the I2C-bus. After the IC address the MSA byte contains the
control of the tuning action via the bits MODE[2:0] and REGC and subaddressing via bits
SA[3:0] (see Figure 7).
The tuner circuit is controlled by the CONTROL register. Any data change in the
CONTROL register has immediate effect and will change the operation of the tuner circuit
accordingly. The subaddress range 00h to 05h includes data that may lead to audible
disturbance when changed. Therefore the subaddress range 00h to 05h is not loaded in
the CONTROL register directly but loaded in a BUFFER register instead. This allows the
IC to take care of tuning actions and mute control, freeing the microcontroller from
cumbersome controls and timings. The subaddress range of 06h to 0Fh does not contain
such critical data. I2C-bus information in the range 06h to 0Fh will be loaded in the
CONTROL register directly (at acknowledge of each byte).
Controlled by a state machine the BUFFER data will be loaded in the CONTROL register
for new settings. However at the same time the CONTROL data is loaded in the BUFFER
register. This register swap action allows a fast return to the previous setting because the
previous data remains available in the BUFFER register (see Figure 8 and Figure 9).
Via MODE several operational modes can be selected for the state machine. MODE offers
all standard tuning actions as well as generic control for flexibility. The state machine
controls the tuner by controlling I2C-bus data and internal circuits like the IF counter and
mute. Action progress is monitored by the accompanying signal processor via the
AFSAMPLE and AFHOLD lines, this way functions like weak signal processing can be
controlled complementary to the tuner action.

The state machine operation starts at the end of transmission (P = STOP). In case a
previous action is still active this is ignored and the new action defined by MODE is started
immediately. When only the address byte is transmitted no action is started however
(device presence test).
To minimize the I2C-bus transmission time only bytes that include data changes need to
be written. Following the MSA byte the transmission can start at any given data byte
defined by the subaddress (SA) bits.
Furthermore when writing the buffered range either the current BUFFER data or the
current CONTROL data can be used as default, controlled by the REGC bit: with
REGC = 0 any BUFFER data that is not newly written via I2C-bus remains unchanged. In
general the BUFFER register will contain the previous tuner setting so this becomes
default for the new setting. When only the MSA byte is transmitted defining a tuning
MODE with REGC = 0 the tuner will return to its previous settings (see Figure 8). Instead
with REGC = 1 the BUFFER register is loaded with data from the CONTROL register first,
this way not written BUFFER data equals the CONTROL data. Since the CONTROL
register contains the current tuner setting with REGC = 1 the current tuner setting is
default for the new setting. When a tuning MODE action is defined with REGC = 1 the
tuner will keep its current settings (CONTROL = current) for all data that is not newly
written during the transmission (see Figure 9).
After power-on reset, all registers are in their default settings. The tuning mute circuit is
muted. The control signals for the signal processors are set to AFSAMPLE = HIGH and
AFHOLD = HIGH. An action of the state machine de-mutes the circuit.

When the write transmission of a state machine command starts during a mute state of the state machine,
the sequences of the state machine start immediately with the actions which follow the mute period in the
standard sequence (see Figure 11, Figure 13, Figure 15, Figure 17 and Figure 19).
[2]
In the modes preset and search the AM AGC time constant is set to fast during the period of complete
mute.
[3]
The AF update sequence can also be started by pulling the AFHOLD pin LOW. In this case the AF
information should be loaded into the BUFFER before. LOW period for a correct AF update timing:
tLOW > 20 µs. Between the end of the I2C-bus transmission and the falling edge of the AFHOLD pulse a
delay of ≥ 20 µs is necessary.

8.2.11.1
Factory alignment of IFCAP
FM IF filter operation point alignment (data byte IFCAP): a single alignment of the FM IF
filter operation range secures an accurate and continuous frequency setting over the full
temperature range and all FM bands.
1. Set bit IFCAPA = 1 to disable internal IFCAP control
2. Increase bit IFCAP from 0 upwards until I2C-bus read bit IFCAPG (read data byte 4,
ID) changes from logic 0 to logic 1
3. Save this IFCAP setting as alignment value
4. Set bit IFCAPA = 0 to return to normal operation
8.2.11.2
Initialization of the radio
During radio initialization bit IFCAPA = 1 is used for writing the stored IFCAP alignment
value. Afterwards bit IFCAPA = 0. After the initialization repeated writing of the IFCAP
byte with the identical IFCAP alignment value is only allowed with bit IFCAPA = 0.
8.2.11.3
Factory alignment of IFCF
FM IF filter center frequency alignment (data byte IFCF): to correct IF frequency errors
caused by an error in the crystal frequency the alignment is preferably performed for every
FM band in use. A test frequency in the center of the band is preferred. An accurate
alignment result is realized by testing for symmetrical filter attenuation.
1. Set RF generator level VRF = 200 µV
2. Set bit IFWB = 1 for better accuracy (20 kHz bandwidth)
3. Set bit IFCFA = 1 to enable fast settling of the filter frequency
4. Test high side of filter curve: tune to fRF − 50 kHz (Europe/USA) or fRF + 33.3 kHz
(Japan/OIRT)
5. Change IFCF[5:0] from 0 to 63 and note the read result LEV[7:0] (level voltages)
6. Test low side of filter curve: tune to fRF + 50 kHz (Europe/USA) or fRF − 33.3 kHz
(Japan/OIRT)
7. Change IFCF[5:0] from 0 to 63 and note the level voltages
8. Find the IFCF[5:0] value where both level curves cross (lowest difference) and save
this IFCF[5:0] value
9. Set bit IFWB = 0 to return to normal operation
10. Set bit IFCFA = 0 to return to normal operation

13. I2C-bus characteristics
The maximum I2C-bus communication speed is 400 kbit/s. The TEF6862HL is compatible
with the autogate function of the TEF689xH. SDA and SCL HIGH and LOW internal
thresholds are specified according to an I2C-bus voltage range from 2.5 V to 3.3 V
including I2C-bus voltage tolerances of ±10 %. The I2C-bus interface tolerates also SDA
and SCL signals from a 5 V bus. Restrictions for VIL in a 5 V application can be derived
from Table 56.

17. Soldering
17.1 Introduction to soldering surface mount packages
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.
17.2 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 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 seconds and 200 seconds depending on heating method.
Typical reflow temperatures range from 215 °C to 260 °C depending on solder paste
material. The peak top-surface temperature of the packages should be kept below:

17.3 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.
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.
• 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.
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 of the leads in the wave ranges from 3 seconds 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.
17.4 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 seconds to 5 seconds between 270 °C and 320 °C.

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.

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, QFP and TQFP 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 soldering or manual soldering is suitable for PMFP packages.
