7 FUNCTIONAL DESCRIPTION

7.1 Oscillators

7.1.1 VCO Thevaractortuned VCO providesthelocaloscillator signal

for both FM and AM mixer 1. It has a frequency range of

162.9 to 248.2 MHz.

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

• Referencefrequency (75.368 kHz) fortheTEA688x (car

audio signal processor - CASP) or TEF689x (car radio integrated signal processor - CRISP).

7.2 DAA

To reduce the numberof 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 centre DAA – Centre frequency alignment (7-bit) of integrated

FM IF2 dynamic selectivity.

7.3 FM signal channel

7.3.1 FM MIXER 1 FM quadraturemixer converts FM RF (65 to 108 MHzand

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 to 107.9 MHz

• US weather FM = 162.4 to 162.55 MHz

• Europe FM = 87.5 to 108 MHz

• Japan FM = 76 to 91 MHz

• East Europe FM = 65 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 forsearch tuning.The AGC sourcesa constant10 mA current intothe FMPIN diode in AM mode.

7.3.4 FM IF AMPLIFIER

The FM IF amplifier provides 18 dB amplification withhigh 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.

Page 10

Philips Semiconductors Product speciﬁcation

New In Car Entertainment car radio tuner IC with Precision Adjacent Channel Suppression (NICE-PACS)

7.3.6 FM IF2 DYNAMIC SELECTIVITY The IF bandwidth of the FM IF2 is automatically adjusted

depending on modulation and reception conditions. The centre frequency of the selectivity is adjusted by a 7-bit instruction via the I2C-bus. The dynamic selectivity mode and three fixed bandwidths (60, 90 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 FM MPX SOFT MUTE Muting depth and start of muting are adjustable via the

I2C-bus (see Figs 8 and 9).

7.3.9 ADJACENT CHANNEL DETECTOR AND THRESHOLD

EXTENSION

In the event of breakthrough of a strong neighbouring transmitter, the IF2 bandwidth is reduced dynamically. At lowRF inputvoltages and lowmodulation levels theIF2 bandwidth is reduced to achieve improved sensitivity by demodulator threshold extension.

7.4.2 AM RF AGC

The AM wideband AGC in front of the first AM mixer is realized first bya cascadedNPN transistor, whichcontrols the transconductance of theRF 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 totalpower 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 I 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.

TEA6849H

C-bus) and

7.3.10 BANDWIDTH CONTROL ‘ACTIVE’ FLAG (PIN IFBWFLAG)

Flag output IBFW = 1 from pin IFBWFLAG indicates that the IF2 bandwidth is reduced.

7.3.11 BANDWIDTH CONTROL MONITOR VOLTAGE (PIN V

Theactual bandwidth isindicated by a voltageat pin V 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 doubleconversion 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:

• LW = 144 to 288 kHz

• MW = 530 to 1710 kHz (US AM band)

• SW = 5.73 to 9.99 MHz (including the 31 m, 41 m and

49 m bands).

IFBW

)

IFBW

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.

Notes

1. To avoiddamage and wrong operation it is necessary to keep all 8.5 Vsupply voltagesat 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.

12.1 I

Informationaboutthe I2C-buscanbe found inthebrochure

“The I2C-bus and how to use it”

9398 393 40011). The standard I2C-bus specification is expanded by the

following definitions. IC addresses:

• 1st IC address C2H: 1100001 R/W

• 2nd IC address C0H: 1100000 R/

Structure of the I increment.

Subaddresses are not used. A second I2C-bus address can be selected by connecting

pin FREF via a 68 kΩ resistor to GND. Exception to the standard I2C-bus specification:

• The data hold time t

12.1.1 DATA TRANSFER

C-bus speciﬁcation

C-bus logic: slave transceiver with auto

HD;DAT

(order number

must be at least 1 µs.

12.1.2 I 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 ofthe 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.

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 anFM frequency, twoI2C-bus transmissions are necessary:

• First: bit MUTE = 1

• Second: bit MUTE = 0.

12.1.4 DEFAULT SETTINGS No default settings at power-on reset. One I2C-bus

transmission is required to program the IC.

C-BUS PULL-UP RESISTORS

TEA6849H

Data sequence: address, byte 0, byte 1, byte 2, byte 3, byte 4, byte 5, byte 6, andbyte 7. The data transfer has to be in this order. The LSB = 0 indicates a WRITE operation to the TEA6849H.

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 thetransfer of a byte is not completed, this byte is lost

and the previous information is available.

16 SOLDERING

16.1 Introduction to soldering surface mount packages

Thistext gives averybrief insight to acomplextechnology. 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). There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for certainsurface mount ICs, butitis not suitableforfinepitch SMDs. In these situations reflow soldering is recommended.

16.2 Reﬂow soldering

Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied tothe printed-circuit boardby 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 and 200 seconds depending on heating method.

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:

• below 220 °C (SnPb process) or below 245 °C (Pb-free

process) – for all BGA and SSOP-T packages – for packages with a thickness ≥ 2.5 mm – for packages with a thickness < 2.5 mm and a

volume ≥ 350 mm3 so called thick/large packages.

• below 235 °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.

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

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.

• Forpackages with leads onfoursides, the footprintmust be placedat 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 packagemust 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 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.

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.

When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C.

TEA6849H

16.3 Wave soldering

Conventional single wave soldering is not recommended forsurface mount devices (SMDs)orprinted-circuit boards with a high component density, as solder bridging and non-wetting can present major problems.

Notes

1. For more detailedinformation on theBGApackages refer tothe

“(LF)BGAApplication Note

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 morethan one soldering cycle or subjected to infrared reflow soldering with peaktemperature 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 apitch (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. Hot bar or manual soldering is suitable for PMFP packages.
