7 FUNCTIONAL DESCRIPTION

7.1 Oscillators

7.1.1 VCO TheL and CtunedVCO provides the local oscillator signal

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

151.2 to 248.2 MHz.

7.1.2 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

• 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).

7.1.3 PLL Fast synthesizer PLL tuning system with local control for

inaudible RDS updating.

7.2 FM signal channel

7.2.1 DAA 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.

TEA6842H

If the keyed AGC function is activated, the AGC function is keyed by the narrow band level (IF).

The AGC PIN diode drive can be set via the I2C-bus to local function for search tuning.

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.

7.2.5 FM DEMODULATOR The FM quadrature demodulator includes automatic

centre frequency adjustment and THD compensation.

7.2.6 FM MPX SOFT MUTE Muting depth and start of muting are adjustable via the

I2C-bus.

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.

Attack and decay time can be set with an external timing capacitor. The detector has a buffered output.

7.3 AM signal channel

7.3.1 AM TUNER The AM tuner is realized in a double conversion technique

and is capable of selecting LW, MW and SW bands.

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.

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 = 65.8 to 74 MHz.

7.2.3 FM KEYED AGC The AGC threshold is programmable and the keyed AGC

function is switchable via the I2C-bus.

2003 Dec 19 9

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 = 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).

7.3.2 AM RF AGC AND IF2 AGC 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.

7.3.3 AM AF OR IF2 SWITCH 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.

Philips Semiconductors Product speciﬁcation

New In Car Entertainment (NICE) extended car radio

7.3.4 AM SOFT 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.

7.3.5 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.

Triggersensitivitycanbemodifiedby changing the resistor value at pin AMNBHOLD.

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.

TEA6842H

7.5 Input for external mute

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.

7.6 Buffer output for weather band ﬂag

In weather band mode the output is HIGH.

7.7 Test mode

The test mode of the IC is activated by connecting pin FREF through a 100 kΩ resistor to V

The test mode is intended for IC test during IC and radio manufacturing.

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.

12 I2C-BUS PROTOCOL

12.1 I

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/W.

A second I2C-bus address can be selected by connecting pin FREF via a 68 kΩ resistor to GND.

Structure of the I increment.

Subaddresses are not used. Remark:TheI2C-busoperatesatamaximumclock 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.

C-bus speciﬁcation

C-bus logic: slave transceiver with auto

TEA6842H

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.

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.

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 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.

12.1.3 FREQUENCY SETTING

C-BUS PULL-UP RESISTORS

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 thisorder.TheLSB = 0 indicates a WRITE operationtothe TEA6842H.

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.

address (write) A

Notes

1. S = START condition.

2. A = acknowledge.

3. P = STOP condition.

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.

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

transmission is required to program the IC.

16 SOLDERING

16.1 Introduction to soldering surface mount packages

Thistextgivesaverybriefinsighttoacomplextechnology. 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 certainsurfacemountICs,butitisnotsuitable for fine pitch 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 totheprinted-circuitboardby 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 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 – 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.

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

TEA6842H

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.

• Forpackageswithleadsonfoursides,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 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.

16.3 Wave soldering

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

Notes

1. FormoredetailedinformationontheBGApackagesrefer to the

“(LF)BGAApplicationNote

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.
