tuner ic with precision adjacent channel suppression (nice-pacs) TEA6848H 7 functional description 7.1 oscillators 7.1.1 vco the varactor tuned vco provides the local oscillator signal for both fm and am mixer 1. it has a frequency range of 162.9 to 248.2 mhz. 7.1.2 pll fast synthesizer pll tuning system with local control for inaudible rds updating. 7.1.3 c rystal 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 and fm mixer 2 reference frequency for the if counter timing signal for the rds update algorithm reference frequency (75.368 khz) for the tea688x (car audio signal processor - casp) or tef689x (car radio integrated signal processor - crisp). 7.2 daa to reduce the number of manual alignments in production the following i 2 c-bus controlled digital auto alignment (daa) functions are included: fm rf daa C 7-bit daa circuitry for the conversion of the vco tuning voltage to a controlled alignment voltage for the fm antenna tank circuit fm and am level daa C level daa circuitry for alignment of slope (3-bit) and starting point (5-bit) of the level curve if2 centre daa C centre frequency alignment (7-bit) of integrated fm if2 dynamic selectivity. 7.3 fm signal channel 7.3.1 fm mixer 1 fm quadrature mixer converts fm rf (65 to 108 mhz and weather band) 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 to 74 mhz. 7.3.2 b uffer output for weather band flag ( pin wbflag) the buffer output on pin wbflag is high for weather band mode. 7.3.3 fm keyed agc the agc threshold is programmable and the keyed agc function is switchable via the i 2 c-bus. agc detection occurs at the input of the first fm mixer. if the keyed agc function is activated, the agc is keyed only by the narrow band level. the agc pin diode drive can be activated via the i 2 c-bus as a local function for search tuning. the agc sources a constant 10 ma current into the fm pin diode in am mode. 7.3.4 fm if amplifier the fm if amplifier provides 18 db amplification with high linearity over a wide dynamic range. 7.3.5 fm mixer 2 the fm mixer 2 converts 10.7 mhz fm if1 to 450 khz fm if2 in i and q phase to achieve image rejection in the demodulator. 2004 nov 12 10 philips semiconductors product speci?cation new in car entertainment car radio tuner ic with precision adjacent channel suppression (nice-pacs) TEA6848H 7.3.6 fm if2 dynamic selectivity the if bandwidth of the fm if2 is automatically adjusted depending on modulation and reception conditions. the centre frequency of the selectivity is adjusted by a 7-bit instruction via the i 2 c-bus. the dynamic selectivity mode and three fixed bandwidths ( 60, 90 and 130 khz ) can be selected via the i 2 c-bus. the if2 bandwidth is set to 13 khz in weather band mode. 7.3.7 fm quadrature demodulator the fm quadrature demodulator is adjustment free. 7.3.8 a djacent channel detector and threshold extension in the event of breakthrough of a strong neighbouring transmitter, the if2 bandwidth is reduced dynamically. at low rf input voltages and low modulation levels the if2 bandwidth is reduced to achieve improved sensitivity by demodulator threshold extension. 7.3.9 b andwidth control active flag ( pin ifbwflag) flag output ibfw = 1 from pin ifbwflag indicates that the if2 bandwidth is reduced. 7.3.10 b andwidth control monitor voltage ( pin v ifbw ) the actual bandwidth is indicated by a voltage at pin v ifbw that is proportional, not linear, to the if bandwidth. 7.4 am signal channel 7.4.1 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. 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 = 530 to 1710 khz (us am band) sw = 5.73 to 9.99 mhz (including the 31 m, 41 m and 49 m bands). 7.4.2 am rf agc the am wideband agc in front of the first am mixer is realized first by a cascaded npn transistor, which controls the transconductance of the rf amplifier jfet with 10 db of agc range. second, an am pin diode stage with antenna type and frequency dependent agc range is available. the minimum jfet drain source voltage is controlled by a dc feedback loop (pin vamcasfb) in order to limit the cascode agc range to 10 db. if the cascode agc is not required, a simple rf agc loop is possible by using only a pin diode. in this event pins vamcasfb and vamcas have to be open-circuit. in fm mode, the cascade switches off the jfet bias current to reduce total power consumption. the pin diode is biased by 1 ma in fm mode. the agc detection points for am agc are at the first am mixer input (threshold programmable via the i 2 c-bus) and the if2 agc input (fixed threshold). 7.4.3 am detector 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. soft mute function is controlled by the i 2 c-bus in am mono mode. 7.4.4 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. trigger sensitivity can be modified by adding an external resistor at pin amnbhold. 7.5 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 i 2 c-bus. 2004 nov 12 11 philips semiconductors product speci?cation new in car entertainment car radio tuner ic with precision adjacent channel suppression (nice-pacs) TEA6848H 7.6 if2 ?lter gain alignment the 4-bit filter gain alignment reduces the change in if filter gain spread when the bandwidth is changed in dynamic mode from 155 khz (maximum) to 25 khz (minimum). a frequency has to be chosen in the middle of european/us fm band, japan band or oirt band (for east europe) and the ic has to be set into dynamic bandwidth mode (if2 bandwidth is 155 khz). setting and clearing the fmbw bit continuously allows the adjustment of the gain alignment to minimum change in am/fm dc level. 7.7 frequency offset detector/alignment a very strong undesired neighbouring signal causes offset in the demodulator in case of weak desired input signal. the frequency offset detector reduces the bandwidth of the if2 filter when the detected offset in the demodulator is too large. there are four bits available for frequency offset detector alignment. every band has to be aligned separately. tuning has to be set to middle of the band, input signal unmodulated, bit ifbw = 1 (alignment voltage will be given to pin ifbwflag). the dc voltage at pin ifbwflag has to be aligned to the minimum value. 8 limiting values in accordance with the absolute maximum rating system (iec 60134). notes 1. to avoid damage 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 interference cannot pull down the 8.5 v supply below the 5 v supply. 2. machine model (r = 0 w , c = 200 pf). 3. human body model (r = 1.5 k w , c = 100 pf). 9 thermal

40011). the standard i 2 c-bus specification is expanded by the following definitions. ic addresses: 1st ic address c2h: 1100001 r/ w 2nd ic address c0h: 1100000 r/ w. structure of the i 2 c-bus logic: slave transceiver with auto increment. subaddresses are not used. a second i 2 c-bus address can be selected by connecting pin fref via a 68 k w resistor to gnd. 12.1.1 d ata transfer data sequence: address, byte 0, 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 TEA6848H. 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. 12.1.2 i 2 c- bus pull - up resistors when the ic is used together with the tea688x or tef689x and both scl and sda lines are connected via the i 2 c-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 i 2 c-bus pull-down can occur switching off the tuner ic supply when the i 2 c-bus buffer interface of the tea688x or tef689x is enabled for data transfer to the tuner ic. 12.1.3 f requency 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 i 2 c-bus transmissions are necessary: first: bit mute = 1 second: bit mute = 0. 12.1.4 d efault settings no default settings at power-on reset. one i 2 c-bus transmission is required to program the ic. 12.1.5 t iming requirements table 1 timing requirements of i 2 c-bus software function timing switching from fm to am 400 ms (10 m f at pin cagc) switching from am to fm 100 ms (10 m f at pin cagc; wideband position has to be set for at least 100 ms to activate speed-up circuitry) start-up in fm mode wideband position has to be set for at least 100 ms to activate speed-up circuitry switching to dynamic mode 500 m s (18 nf at pin tacd; wideband position has to be set for at least 500 m s to activate clamping circuitry at pin tacd) 2004 nov 12 32 philips semiconductors product speci?cation new in car entertainment car radio

in car entertainment car radio tuner ic with precision adjacent channel suppression (nice-pacs) TEA6848H 16 soldering 16.1 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 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 re?ow 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. 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 seconds and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 c 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) C for all bga, htsson..t and ssop..t packages C for packages with a thickness 3 2.5 mm C for packages with a thickness < 2.5 mm and a volume 3 350 mm 3 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 mm 3 so called small/thin packages. 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. 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): C 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; C 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 of the leads in the wave ranges from 3 seconds 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 seconds to 5 seconds between 270 c and 320 c. 2004 nov 12 60 philips semiconductors product speci?cation new in car entertainment car radio tuner ic with precision adjacent channel suppression (nice-pacs) TEA6848H 16.5 suitability of surface mount ic packages for wave and re?ow soldering methods 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, qfp and tqfp 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 soldering or manual soldering is suitable for pmfp packages. package (1) soldering method wave reflow (2) bga, htsson..t (3) , lbga, lfbga, sqfp, ssop..t (3) , tfbga,
