input circuit defines an fm band filter. the gain of the lna is controlled by the rf agc circuit. 7.2 fm mixer the fm quadrature mixer converts the fm rf (76 mhz to 108 mhz) to an if of 225 khz. 7.3 vco the varactor tuned lc vco provides the local oscillator (lo) signal for the fm quadrature mixer. the vco frequency range is 150 mhz to 217 mhz. 7.4 crystal oscillator the crystal oscillator can operate with a 32.768 khz clock crystal or a 13 mhz crystal. the temperature drift of standard 32.768 khz clock crystals limits the operational temperature range from - 10 c to +60 c. the pll synthesizer can be clocked externally with a 32.768 khz, a 6.5 mhz or a 13 mhz signal via pin xtal2. the crystal oscillator generates the reference frequency for: the reference frequency divider for the synthesizer pll the timing for the if counter the free-running frequency adjustment of the stereo decoder vco the centre frequency adjustment of the if filters. 7.5 pll tuning system the pll synthesizer tuning system is suitable to operate with a 32.768 khz or a 13 mhz reference frequency generated by the crystal oscillator or applied to the ic from an external source. the synthesizer can also be clocked via pin xtal2 at 6.5 mhz. the pll tuning system can perform an autonomous search tuning function. 7.6 rf agc the rf agc prevents overloading and limits the amount of intermodulation products created by strong adjacent channels. 2004 sep 13 8 philips semiconductors product speci?cation low-power fm stereo radio for handheld applications TEA5767HL 7.7 if ?lter fully integrated if filter. 7.8 fm demodulator the fm quadrature demodulator has an integrated resonator to perform the phase shift of the if signal. 7.9 level voltage generator and analog-to-digital converter the fm if analog level voltage is converted to 4 bits digital data and output via the 3-wire bus. 7.10 if counter the if counter outputs a 7-bit count result via the 3-wire bus. 7.11 soft mute the low-pass filtered level voltage drives the soft mute attenuator at low rf input levels. the soft mute function can be switched off via the 3-wire bus. 7.12 mpx decoder the pll stereo decoder is adjustment-free. the stereo decoder can be switched to mono via the 3-wire bus. 7.13 signal dependent mono to stereo blend with a decreasing rf input level the mpx decoder blends from stereo to mono to limit the output noise. the continuous mono to stereo blend can also be programmed via the 3-wire bus to an rf level depending switched mono to stereo transition. stereo noise cancelling (snc) can be switched off via the 3-wire bus. 7.14 signal dependent af response the audio bandwidth will be reduced with a decreasing rf input level. this function can be switched off via the 3-wire bus. 7.15 software programmable ports two software programmable ports (open-collector) can be addressed via the 3-wire bus. the port 1 (pin swport1) function can be changed with write data byte 4 bit 0 (see table 10). pin swport1 is then output for the ready flag of read byte 1. 8 3-wire bus and bus-controlled functions 8.1 3-wire bus speci?cation the 3-wire bus controls the write/read, clock and data lines and operates at a maximum clock frequency of 400 khz. before any read or write operation the pin busenable has to be high for at least 10 m s. hint : by using the standby bit the ic can be switched into a low current standby mode. in standby mode the ic must be in the write mode. when the ic is switched to read mode, during standby, the ic will hold the data line down. the standby current can be reduced by deactivating the bus interface (pin busenable low). if the bus interface is deactivated (pin busenable low) without the standby mode being programmed, the ic maintains normal operation, but is isolated from the clock and data line. 8.1.1 d ata transfer data sequence: byte 1, byte 2, byte 3, byte 4 and byte 5 (the data transfer has to be in this order). a positive edge at pin write/read enables the data transfer into the ic. the data has to be stable at the positive edge of the clock. data may change while the clock is low and is written into the ic on the positive edge of the clock. data transfer can be stopped after the transmission of new tuning information with the first two bytes or after each following byte. a negative edge at pin write/read enables the data transfer from the ic. the write/read pin changes while the clock is low. with the negative edge at pin write/read the msb of the first byte occurs at pin data. the bits are shifted on the negative clock edge to pin data and can be read on the positive edge. to do two consecutive read or write actions, pin write/read has to be toggled for at least one clock period. when a search tuning request is sent, the ic autonomously starts searching the fm band; the search direction and search stop level can be selected. when a station with a field-strength equal to or greater than the stop level is found, the tuning system stops and the ready flag bit is set to high. when, during search, a band limit is reached, the tuning system stops at the band limit and the band limit flag bit is set to high. the ready flag is also set to high in this case. 2004 sep 13 9 philips semiconductors product speci?cation low-power fm stereo radio for handheld applications TEA5767HL the software programmable output (swport1) can be programmed to operate as a tuning indicator output. as long as the ic has not completed a tuning action, pin swport1 remains low. the pin becomes high, when a preset or search tuning is completed or when a band limit is reached. the reference frequency divider of the synthesizer pll is changed when the msb in byte 5 is set to logic 1. the tuning system can then be clocked via pin xtal2 at 6.5 mhz. 8.1.2 p ower - on reset at power-on reset the mute is set, all other bits are random. to initialize the ic all bytes have to be transferred. 8.2 writing data

applications TEA5767HL 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 sep 13 34 philips semiconductors product speci?cation low-power fm stereo radio for handheld applications TEA5767HL 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)
