FUNCTIONAL DESCRIPTION 7.1 7.1.1 Oscillators The AGC PIN diode drive can be set via the I2C-bus to local function for search tuning. VCO The L and C tuned VCO 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 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. CRYSTAL OSCILLATOR 7.2.5 The crystal oscillator provides a 20.5 MHz signal that is used for: FM DEMODULATOR The FM quadrature demodulator includes automatic centre frequency adjustment and THD compensation. • Reference frequency for frequency synthesizer PLL • Local oscillator for AM mixer 2 • Reference frequency for the IF counter 7.2.6 • Timing signal for the RDS update algorithm Muting depth and start of muting are adjustable via the I2C-bus. • Reference frequency (75.368 kHz) for the TEA688x (car audio signal processor - CASP) or TEF689x (car radio integrated signal processor - CRISP). 7.1.3 7.2.7 7.2.1 Attack and decay time can be set with an external timing capacitor. The detector has a buffered output. FM signal channel 7.3 DAA 7.3.1 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. 7.2.2 AM TUNER 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: FM I/Q MIXER • 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). 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 7.3.2 • US weather FM = 162.4 to 162.55 MHz 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. • Europe FM = 87.5 to 108 MHz • Japan FM = 76 to 91 MHz • East Europe FM = 65.8 to 74 MHz. 7.3.3 FM KEYED AGC 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. The AGC threshold is programmable and the keyed AGC function is switchable via the I2C-bus. 2003 Dec 19 AM signal channel The AM tuner is realized in a double conversion technique and is capable of selecting LW, MW and SW bands. 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. 7.2.3 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. PLL Fast synthesizer PLL tuning system with local control for inaudible RDS updating. 7.2 FM MPX SOFT MUTE 9 Philips Semiconductors Product specification New In Car Entertainment (NICE) extended car radio 7.3.4 TEA6842H 7.5 AM SOFT MUTE Input for external 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. 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. 7.3.5 7.6 AM NOISE BLANKER Buffer output for weather band flag 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. In weather band mode the output is HIGH. Trigger sensitivity can be modified by changing the resistor value at pin AMNBHOLD. The test mode of the IC is activated by connecting pin FREF through a 100 kΩ resistor to VDDA1. 7.4 The test mode is intended for IC test during IC and radio manufacturing. 7.7 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. Test mode In test mode the settling time of the AM IF2 AGC is reduced to less than 100 ms in the nominal application. 8 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

IC addresses: 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. • 1st IC address C2H: 1100001 R/W • 2nd IC address C0H: 1100000 R/W. 12.1.2 A second I2C-bus address can be selected by connecting pin FREF via a 68 kΩ resistor to GND. 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. Structure of the I2C-bus logic: slave transceiver with auto increment. Subaddresses are not used. Remark: The I2C-bus operates at a maximum clock 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. 12.1.1 I2C-BUS PULL-UP RESISTORS 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 an FM frequency, two I2C-bus transmissions are necessary: 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 this order. The LSB = 0 indicates a WRITE operation to the TEA6842H. • First: bit MUTE = 1 • Second: bit MUTE = 0. Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of the byte. 12.1.4 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. DEFAULT SETTINGS No default settings at power-on reset. One I2C-bus transmission is required to program the IC.

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). • 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): 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. 16.2 – 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. Reflow soldering The footprint must incorporate solder thieves at the downstream end. 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. • 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. 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. 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 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: 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. • below 225 °C (SnPb process) or below 245 °C (Pb-free process) A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. – for all BGA, HTSSON-T and SSOP-T packages 16.4 – for packages with a thickness 2.5 mm 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. – 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. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 16.3 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. 2003 Dec 19 Manual soldering 62 Philips Semiconductors Product specification New In Car Entertainment (NICE) extended car radio 16.5 TEA6842H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE REFLOW(2) BGA, HTSSON..T(3), LBGA, LFBGA, SQFP, SSOP..T(3), TFBGA, USON, VFBGA not suitable suitable DHVQFN, HBCC, HBGA, HLQFP, HSO, HSOP, HSQFP, HSSON, HTQFP, HTSSOP, HVQFN, HVSON, SMS not suitable(4) suitable PLCC(5), SO, SOJ suitable suitable not recommended(5)(6) suitable SSOP, TSSOP, VSO, VSSOP not recommended(7) suitable CWQCCN..L(8), PMFP(9), WQCCN..L(8) not suitable LQFP, QFP, TQFP not suitable Notes 1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); 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, 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. 2003 Dec 19 63 Philips Semiconductors Product specification New In Car Entertainment (NICE) extended car radio TEA6842H 17 DATA SHEET STATUS LEVEL DATA SHEET STATUS(1) PRODUCT STATUS(2)(3) Development DEFINITION I Objective data II Preliminary data Qualification This data sheet contains data from the preliminary specification.
