The PIN diode drive can be activated via the I2C-bus as a local or distance function. CRYSTAL OSCILLATOR The AGC threshold is programmable and the keyed AGC function is switchable via the I2C-bus. The crystal oscillator provides a 20.5 MHz signal that is used for: * Reference frequency for frequency synthesizer PLL 7.2.4 * Local oscillator for AM mixer 2 * Timing signal for the RDS update algorithm * Reference frequency (75.4 kHz) for the TEA6880H (car audio signal processor - CASP) or TEF6890H (car radio integrated signal processor). 7.2.5 7.1.3 7.3 PLL 7.3.1 AM signal channel AM TUNER INCLUDING MIXER 1 AND MIXER 2 The AM tuner is realized in a double conversion technique and is capable of selecting LW, MW and SW bands. FM signal channel 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: 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. 7.2.2 FM DEMODULATOR The FM quadrature demodulator includes automatic centre frequency adjustment and THD compensation. Fast synthesizer PLL tuning system with local control for inaudible RDS updating. 7.2.1 FM IF AMPLIFIERS The two FM IF amplifiers provide 10 dB and 4 dB amplification with high linearity and dynamic range. * Reference frequency for the IF counter 7.2 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. 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 TEA6845H * 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). 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. 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 via the I2C-bus. 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 7.3.3 * Europe FM = 87.5 to 108 MHz * Japan FM = 76.0 to 91 MHz The AM detector provides AM level information and AM AF or AM IF2. * East Europe FM = 65.8 to 74 MHz. 7.3.4 AM DETECTOR AM AF OR IF2 SWITCH 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. 2003 Feb 04 9 Philips Semiconductors Product specification New In Car Entertainment (NICE) car radio 7.3.5 If the test mode is enabled by pin FREF: AM NOISE DETECTOR AND BLANKER * The settling time of the AM IF2 AGC is reduced to less than 100 ms in the nominal application 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. * The digital-to-analog converters for the antenna DAA and the level DAA can be clocked directly by the SCL line of the I2C-bus Trigger sensitivity can be modified by changing the resistor value at pin AMNBHOLD. 7.3.6 TEA6845H * The output at pin FREF can be selected by the I2C-bus: TEA6880H or TEF6890H reference frequency, PLL reference frequency or PLL programmable divider output frequency 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. * The RDS update control circuit can be clocked directly via pin DAATD 7.4 * Pin T1AMAGC can be used to enable the load PLL circuit of the RDS update control circuit Test mode * Charge pumps can be set into 3-state mode. The test mode of the IC is activated by: * Sending the test byte (byte 5) to the IC * Connecting pin FREF through a 100 k resistor to VDDA1 * Applying 50 A to pin FREF. 8 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

The LSB = 0 indicates a WRITE operation to the TEA6845H. 12 I2C-BUS PROTOCOL 12.1 TEA6845H I2C-bus specification Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of the byte. Information about the I2C-bus can be found in the brochure "The I2C-bus and how to use it" (order number 9398 393 40011). 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. The standard I2C-bus specification is expanded by the following definitions. IC addresses: When writing to the transceiver by using the STOP condition before completion of the whole transfer: * 1st IC address C2: 1100001 * The remaining bytes will contain the old information * 2nd IC address C0: 1100000. Structure of the increment. I2C-bus * If the transfer of a byte is not completed, this byte is lost and the previous information is available. logic: slave transceiver with auto 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 FREF. Subaddresses are not used. Exception to the standard I2C-bus specification: * The data hold time tHD;DAT must be at least 1 s. 12.1.1 12.1.3 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. TEST MODE Connecting pin FREF to VDDA1 via a 100 k resistor or feeding 50 A into that pin switches the IC into the 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 TEA688x or TEF689x reference frequency, the PLL reference frequency divider or the programmable divider output can be switched to pin FREF. 12.1.2 12.1.4 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 * First: bit MUTE = 1 Data sequence: address, byte 1, byte 2, byte 3, byte 4, byte 5, and byte 6. The data transfer has to be in this 2003 Feb 04 I2C-bus pULL-UP RESISTORS * Second: bit MUTE = 0. 28 Philips Semiconductors Product specification New In Car Entertainment (NICE) car radio TEA6845H I2C-bus protocol 12.2 12.2.1 DATA TRANSFER MODE AND IC ADDRESS Table 1 Write mode S(1) address (write) A(2) address (read) A(2) data byte 1 0 0 0 0/1(1) R/W(2) data byte(s) A(2) P(3) Notes 1.

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 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. 15.2 TEA6845H - 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. 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. * 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 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 220 C for thick/large packages, and below 235 C for small/thin packages. 15.3 15.4 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. 2003 Feb 04 Manual soldering 41 Philips Semiconductors Product specification New In Car Entertainment (NICE) car radio 15.5 TEA6845H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE BGA, LBGA, LFBGA, SQFP, TFBGA, VFBGA not suitable suitable(3) DHVQFN, HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS not PLCC(4), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO REFLOW(2) suitable suitable suitable not recommended(4)(5) suitable not recommended(6) 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 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. 4. 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. 5. 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. 6. Wave soldering is 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. 2003 Feb 04 42 Philips Semiconductors Product specification New In Car Entertainment (NICE) car radio TEA6845H 16 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.
