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_1

Product data sheet

Rev. 01 — 14 September 2006

8 of 65

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.

[1] 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:

t_LOW> 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.

alignment of FM IF ﬁlter capacitor value (use read bit IFCAPG)

The fully integrated IF2 ﬁlter of the TEF6862 has to be aligned in order to achieve the

optimum performance at all ambient conditions. The following procedure is used for a

correct factory alignment.

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 V_RF= 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 f_RF− 50 kHz (Europe/USA) or f_RF+ 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 f_RF+ 50 kHz (Europe/USA) or f_RF− 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 V_ILin 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:

July 2004)

Moisture sensitivity precautions, as indicated on packing, must be respected at all times.

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.

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, 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.
