FUNCTIONAL DESCRIPTION FM mixer 1 FM quadrature mixer converts FM RF (65 to 162.55 MHz) to an IF of 10.7 MHz. The FM mixer provides inherent image rejection and high RF sensitivity. FM IF amplifiers The two FM IF amplifiers provide 10 dB and 4 dB amplification with high linearity and dynamic range. It is capable of tuning the US FM, US weather, Europe FM, Japan FM and East Europe FM bands. FM demodulator • US FM = 87.9 to 107.9 MHz The FM quadrature demodulator includes automatic centre frequency adjustment and THD compensation. • US weather = 162.4 to 162.55 MHz • Europe FM = 87.5 to 108 MHz AM tuner • Japan FM = 76.0 to 91 MHz • East Europe FM = 65.8 to 74 MHz. The AM tuner is realized in a double conversion technique and is capable of selecting LW/MW and SW bands. VCO AM mixer 1 converts AM RF to an IF1 of 10.7 MHz, while AM mixer 2 converts 10.7 MHz IF1 to 450 kHz IF2. The L and C tuned VCO provides the Local Oscillator (LO) signal for both FM and AM mixer 1. It has a frequency range of 151.2 to 248.2 MHz. • LW = 144 to 288 kHz • MW = 530 to 1710 kHz (US AM band) Crystal oscillator • SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and 49 m bands). The crystal oscillator provides a 20.5 MHz signal that is used for: AM RF and IF2 AGC • Reference frequency for frequency synthesizer PLL 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 via the I2C-bus. • LO for 2nd AM mixer • Reference frequency for the IF counter • Timing signal for the RDS update algorithm • Reference frequency (75.4 kHz) for the TEA6880H. AM detector PLL The AM detector provides AM level information and AM AF or AM IF2. Fast synthesizer PLL tuning system with local control for inaudible RDS updating. AM AF/IF2 SWITCH The AM output provides either a detected AM Audio Frequency (AF) or the corresponding AM IF2 signal. The IF2 signal can be used for AM stereo decoder processing. DAA Digital Auto Alignment circuitry (FM RF DAA) for the conversion of the VCO tuning voltage to a controlled alignment voltage for the FM antenna tank circuit. AM noise blanker FM keyed AGC 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 2nd mixer. FM contains keyed wide-band RF AGC. AGC detection occurs at the FM mixer. The wide-band RF signal switches a narrow band signal (IF) from the FM IF level detector circuitry that controls the FM RF AGC block. Trigger sensitivity can be modified by changing the resistor value at pin 46. It includes an AGC pin diode drive circuit for the FM RF AGC. The pin diode drive can be activated via the I2C-bus as a local/distance function. 1999 Jul 12 9 Philips Semiconductors Preliminary specification New In Car Entertainment (NICE) car radio TEA6840H • The digital-to-analog converters for the antenna Data Access Arrangement (DAA) and the level DAA can be clocked directly by the SCL line of the I2C-bus FM/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. • The output at pin 15 can be selected by the I2C-bus: TEA6880H reference frequency, PLL reference frequency or PLL programmable divider output frequency Test mode • The RDS update control circuit can be clocked directly via pin 20 The test mode of the IC is activated by: • Sending the test byte (byte 5) to the IC • Connecting pin 15 through a 100 kΩ resistor to VDDA1 • Pin 31 can be used to enable the load PLL circuit of the RDS update control circuit • Applying 50 µA to pin 15. • Charge pumps can be set into 3-state mode. If the test mode is enabled by pin 15: • The settling time of the AM IF2 AGC is reduced to less than 100 ms in the nominal application LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

The LSB = 0 indicates a WRITE operation to the TEA6840H. Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of the byte. I2C-BUS AND I2C-BUS CONTROLLED FUNCTIONS I2C-bus specification The standard I2C-bus specification is expanded by the following definitions. • 2nd chip address C0: 1100000 R/W. 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. Structure of the I2C-bus logic: slave transceiver with auto increment. When writing to the transceiver by using the STOP condition before completion of the whole transfer: • 1st chip address C2: 1100001 R/W • The remaining bytes will contain the old information Subaddresses are not used. • If the transfer of a byte is not completed, this byte is lost and the previous information is available. A second I2C-bus address can be selected by connecting pin 15 via a 68 kΩ resistor to GND. In byte 5, 4 bits are reserved for test mode purposes. Those can only be used when the test mode is activated by the select pin 15. Connecting pin 15 to VDDA1 via a 100 kΩ resistor or feeding 50 µA into that pin switches the IC into the test mode. Hints: When the IC is used together with the Car Analog Sound Processor IC (TEA6880H) and when the SCL and SDA lines are connected via Car Analog Sound Processor IC’s I2C-bus buffer interface, the pull-up resistors of the tuner IC should be connected to the digital supply voltage of the TEA6880H. Otherwise a bus pull-down can occur switching off the tuner IC supply when the I2C-bus buffer interface of the TEA6880H is enabled for data transfer to the tuner IC. TEST MODE During test mode the digital-to-analog converters of the level and antenna DAA functions can be sequenced by the I2C-bus SCL line. During test mode either the TEA6880H reference frequency, the PLL reference frequency divider or the programmable divider output can be switched to pin 15. For new frequency setting, in both AM and FM mode, the programmable divider is enabled by setting the mute bit (data byte 3 bit 7) to logic 1. DATA TRANSFER FOR THE TEA6840H Data sequence: • Address To select an FM frequency, two I2C-bus transmissions are necessary. First data byte 3 bit 7 = 1 and second data byte 3 bit 7 = 0. • Byte 1 • Byte 2 Default settings by power-on reset: To be defined. • Byte 3 • Byte 4 • Byte 5 • Byte 6. 1999 Jul 12 28 Philips Semiconductors Preliminary specification New In Car Entertainment (NICE) car radio Table 1 TEA6840H Data to be received by the IC DATA BYTE BIT 1 0 to 6 7 DESCRIPTION define the setting of the programmable counter of the synthesizer PLL start RDS update bit 7 = 1 no RDS update started bit 7 = 0 2 0 to 7 define the setting of the programmable counter of the synthesizer PLL 3 0 to 6 define the setting of the antenna DAA circuit 7 4 0 1 and 2 3 5 AM mode bit 0 = 1 FM mode bit 0 = 0 for FM mode: FM band and local/distance select for AM mode: division ratio N2 divider (AM band select) and switching for AM stereo IF counter prescaler ratio = 10 bit 3 = 1 IF counter prescaler ratio = 100 bit 3 = 0 5 reference frequency for synthesizer 6 MSB for reference frequency for synthesizer 0 and 1 3 4 IF counter period = 2 ms bit 7 = 1 IF counter period = 20 ms bit 7 = 0 bits only valid in test mode; setting define output at pin 15 external clock for level and antenna DAA enabled (only valid in test mode) bit 2 = 1 external clock for level and antenna DAA disabled (only valid in test mode) bit 2 = 0 3-state active (only valid in test mode) bit 3 = 1 3-state off (only valid in test mode; charge pumps operational) bit 3 = 0 AM soft mute on bit 4 = 1 AM soft mute off bit 4 = 0 5 LSB for wide band AGC setting for AM and FM 6 MSB for wide band AGC setting for AM and FM 7 keyed function on bit 7 = 1 keyed function off bit 7 = 0 0 LSB for the definition of the level slope setting of the level DAA 1 definition of the level slope setting of the level DAA 2 MSB for the definition of the level slope setting of the level DAA 3 LSB for the definition of the starting point setting of the level DAA 4 to 6 7 1999 Jul 12 bit 7 = 1 bit 7 = 0 LSB for reference frequency for synthesizer 2 6 FM audio output muted; writing to programmable divider enabled for AM and FM FM audio output not muted 4 7 RESULT definition of the starting point setting of the level DAA MSB for the definition of the starting point setting of the level DAA 29 Philips Semiconductors Preliminary specification New In Car Entertainment (NICE) car radio Table 2 Table 3 TEA6840H Reference frequency setting in byte 4 BIT 4 BIT 5 BIT 6 FREQUENCY SETTING (kHz) 0 0 0 100 0 0 1 50 0 1 0 25 0 1 1 20 1 0 0 10 1 0 1 10 1 1 0 10 1 1 1 10 AM/FM setting in byte 4 BIT 0 BIT 1 BIT 2 DESCRIPTION 0 0 0 FM standard: dead zone high current charge pump active, FM AGC defined by RF level and threshold level setting by I2C-bus 0 1 0 FM local: dead zone high current charge pump active, FM AGC source current set to maximum 0 0 1 FM East Europe: dead zone high current charge pump switched off, current of low current charge pump set to 1 mA 0 1 1 FM weather band: division ratio N1 set to 1 and I and Q phase shift network switched on, WX flag signal activated 1 0 0 AM mono, N2 divider set to 5 (SW) 1 1 0 AM stereo, N2 divider set to 5 (SW) 1 0 1 AM mono, N2 divider set to 10 (LW, MW) 1 1 1 AM stereo, N2 divider set to 10 (LW, MW) In AM mode dead zone high current charge pump switched off, current of low current charge pump set to 1 mA.

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). • 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; There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. – 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. 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. 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. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C. 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. 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. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. 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: 1999 Jul 12 TEA6840H 40 Philips Semiconductors Preliminary specification New In Car Entertainment (NICE) car radio TEA6840H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE REFLOW(1) WAVE BGA, SQFP not suitable HLQFP, HSQFP, HSOP, HTSSOP, SMS not PLCC(3), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO suitable suitable(2) suitable suitable suitable not recommended(3)(4) suitable not recommended(5) suitable Notes 1. 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”. 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. 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. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP 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. 1999 Jul 12 41 Philips Semiconductors Preliminary specification New In Car Entertainment (NICE) car radio TEA6840H DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
