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. 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 = 162.4 to 162.55 MHz * Europe FM = 87.5 to 108 MHz * Japan FM = 76.0 to 91 MHz * East Europe FM = 65.8 to 74 MHz. VCO 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. Crystal oscillator The crystal oscillator provides a 20.5 MHz signal that is used for: * Reference frequency for frequency synthesizer PLL * 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. PLL Fast synthesizer PLL tuning system with local control for inaudible RDS updating. 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. FM keyed AGC 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. 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.
TEA6840H
The AGC threshold is programmable and the keyed AGC function is switchable via the I2C-bus. FM IF amplifiers The two FM IF amplifiers provide 10 dB and 4 dB amplification with high linearity and dynamic range. FM demodulator The FM quadrature demodulator includes automatic centre frequency adjustment and THD compensation. AM tuner The AM tuner is realized in a double conversion technique and is capable of selecting LW/MW and SW bands. 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. * LW = 144 to 288 kHz * MW = 530 to 1710 kHz (US AM band) * SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and 49 m bands). AM RF 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 via the I2C-bus. AM detector The AM detector provides AM level information and AM AF or AM IF2. 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. 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 2nd mixer. Trigger sensitivity can be modified by changing the resistor value at pin 46.

I2C-BUS AND I2C-BUS CONTROLLED FUNCTIONS I2C-bus specification The standard I2C-bus specification is expanded by the following definitions. * 1st chip address C2: 1100001 R/W * 2nd chip address C0: 1100000 R/W. Structure of the I2C-bus logic: slave transceiver with auto increment. Subaddresses are not used. A second I2C-bus address can be selected by connecting pin 15 via a 68 k resistor to GND. Connecting pin 15 to VDDA1 via a 100 k resistor or feeding 50 A into that pin switches the IC into the test mode. 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. DATA TRANSFER FOR THE TEA6840H Data sequence: * Address * Byte 1 * Byte 2 * Byte 3 * Byte 4 * Byte 5 * Byte 6.
TEA6840H
The data transfer has to be in this order. 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. 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 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. Those can only be used when the test mode is activated by the select pin 15. 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. 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. 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. Default settings by power-on reset: To be defined.

SOLDERING Introduction to soldering surface mount packages This text gives a very brief insight to a complex technology. 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 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. 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. 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 reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 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. 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:
TEA6840H
* 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 is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 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.

REFLOW(1)
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.
