2004 aug 25 10 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 8 functional description figure 1 shows the simplified block diagram of the device which comprises the following functional blocks: vif amplifier tuner agc and vif-agc vif-agc detector frequency phase-locked loop (fpll) detector vco and divider afc and digital acquisition help video demodulator and amplifier sound carrier trap sif amplifier sif-agc detector single reference qss mixer am demodulator fm demodulator and acquisition help audio amplifier and mute time constant radio mode internal voltage stabilizer i 2 c-bus transceiver and mad (module address). 8.1 vif ampli?er the vif amplifier consists of three ac-coupled differential stages. gain control is performed by emitter degeneration. the total gain control range is typically 66 db. the differential input impedance is typically 2 k w in parallel with 3 pf. 8.2 tuner agc and vif-agc this block adapts the voltages, generated at the vif-agc and sif-agc detectors, to the internal signal processing at the vif and sif amplifiers and performs the tuner agc control current generation. the onset of the tuner agc control current generation can be set either via the i 2 c-bus (see table 13) or optionally by a potentiometer at pin top (in case that the i 2 c-bus information cannot be stored). the presence of a potentiometer is automatically detected and the i 2 c-bus setting is disabled. furthermore, derived from the agc detector voltage, a comparator is used to test if the corresponding vif input voltage is higher than 200 m v. this information can be read out via the i 2 c-bus (bit viflev = 1). 8.3 vif-agc detector gain control is performed by sync level detection (negative modulation) or peak white detection (positive modulation). for negative modulation, the sync level voltage is stored at an integrated capacitor by means of a fast peak detector. this voltage is compared with a reference voltage (nominal sync level) by a comparator which charges or discharges the integrated agc capacitor for the generation of the required vif gain. the time constants for decreasing or increasing the gain are nearly equal and the total agc reaction time is fast to cope with aeroplane fluttering. for positive modulation, the white peak level voltage is compared with a reference voltage (nominal white level) by a comparator which charges (fast) or discharges (slow) the external agc capacitor directly for the generation of the required vif gain. the need of a very long time constant for vif gain increase is because the peak white level may appear only once in a field. in order to reduce this time constant, an additional level detector increases the discharging current of the agc capacitor (fast mode) in the event of a decreasing vif amplitude step controlled by the detected actual black level voltage. the threshold level for fast mode agc is typically - 6 db video amplitude. the fast mode state is also transferred to the sif-agc detector for speed-up. in case of missing peak white pulses, the vif gain increase is limited to typically +3 db by comparing the detected actual black level voltage with a corresponding reference voltage. 8.4 fpll detector the vif amplifier output signal is fed into a frequency detector and into a phase detector via a limiting amplifier for removing the video am. during acquisition the frequency detector produces a current proportional to the frequency difference between the vif and the vco signals. after frequency lock-in the phase detector produces a current proportional to the phase difference between the vif and the vco signals. the currents from the frequency and phase detectors are charged into the loop filter which controls the vif vco and locks it to the frequency and phase of the vif carrier. for a positive modulated vif signal, the charging currents are gated by the composite sync in order to avoid signal distortion in case of overmodulation. the gating depth is switchable via the i 2 c-bus.
2004 aug 25 11 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 8.5 vco and divider the vco of the vif-fpll operates as an integrated low radiation relaxation oscillator at double the picture carrier frequency. the control voltage, required to tune the vco to double the picture carrier frequency, is generated at the loop filter by the frequency phase detector. the possible frequency range is 50 to 140 mhz (typical value). the oscillator frequency is divided-by-two to provide two differential square wave signals with exactly 90 degrees phase difference, independent of the frequency, for use in the fpll detectors, the video demodulator and the intercarrier mixer. 8.6 afc and digital acquisition help each relaxation oscillator of the vif-pll and fm-pll demodulator has a wide frequency range. to prevent false locking of the plls and with respect to the catching range, the digital acquisition help provides an individual control, until the frequency of the vco is within the preselected standard dependent lock-in window of the pll. the in-window and out-window control at the fm-pll is additionally used to mute the audio stage (if auto mute is selected via the i 2 c-bus). the working principle of the digital acquisition help is as follows. the pll vco output is connected to a down counter which has a predefined start value (standard dependent). the vco frequency clocks the down counter for a fixed gate time. thereafter, the down counter stop value is analysed. in case the stop value is higher (lower) than the expected value range, the vco frequency is lower (higher) than the wanted lock-in window frequency range. a positive (negative) control current is injected into the pll loop filter and consequently the vco frequency is increased (decreased) and a new counting cycle starts. the gate time as well as the control logic of the acquisition help circuit is dependent on the precision of the reference signal at pin ref. operation as a crystal oscillator is possible as well as connecting this input via a serial capacitor to an external reference frequency, e.g. the tuning system oscillator. the afc signal is derived from the corresponding down counter stop value after a counting cycle. the last four bits are latched and can be read out via the i 2 c-bus (see table 7). also the digital-to-analog converted value is given as current at pin afc. 8.7 video demodulator and ampli?er the video demodulator is realized by a multiplier which is designed for low distortion and large bandwidth. the vif signal is multiplied with the in phase signal of the vif-pll vco. the demodulator output signal is fed into the video preamplifier via a level shift stage with integrated low-pass filter to achieve carrier harmonics attenuation. the output signal of the preamplifier is fed to the vif-agc detector (see section 8.3) and in the sound trap mode also fed internally to the integrated sound carrier trap (see section 8.8). the differential trap output signal is converted and amplified by the following postamplifier. the video output level at pin cvbs is 2 v (p-p). in the bypass mode the output signal of the preamplifier is fed directly through the postamplifier to pin cvbs. the output video level is 1.1 v (p-p) for using an external sound trap with 10 % overall loss. noise clipping is provided in both cases. 8.8 sound carrier trap the sound carrier trap consists of a reference filter, a phase detector and the sound trap itself. a sound carrier reference signal is fed into the reference low-pass filter and is shifted by nominal 90 degrees. the phase detector compares the original reference signal with the signal shifted by the reference filter and produces a dc voltage by charging or discharging an integrated capacitor with a current proportional to the phase difference between both signals, respectively to the frequency error of the integrated filters. the dc voltage controls the frequency position of the reference filter and the sound trap. so the accurate frequency position for the different standards is set by the sound carrier reference signal. the sound trap itself is constructed of three separate traps to realize sufficient suppression of the first and second sound carriers. 8.9 sif ampli?er the sif amplifier consists of three ac-coupled differential stages. gain control is performed by emitter degeneration. the total gain control range is typically 66 db. the differential input impedance is typically 2 k w in parallel with 3 pf.
2004 aug 25 12 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 8.10 sif-agc detector sif gain control is performed by the detection of the dc component of the am demodulator output signal. this dc signal corresponds directly to the sif voltage at the output of the sif amplifier so that a constant sif signal is supplied to the am demodulator and to the single reference qss mixer. by switching the gain of the input amplifier of the sif-agc detector via the i 2 c-bus, the internal sif level for fm sound is 5.5 db lower than for am sound. this is to adapt the sif-agc characteristic to the vif-agc characteristic. the adaption is ideal for a picture-to-sound fm carrier ratio of 13 db. via a comparator, the integrated agc capacitor is charged or discharged for the generation of the required sif gain. due to am sound, the agc reaction time is slow (f c < 20 hz for the closed agc loop). for reducing this am sound time constant in the event of a decreasing if amplitude step, the load current of the agc capacitor is increased (fast mode) when the vif-agc detector (at positive modulation mode) operates in the fast mode too. an additional circuit (threshold approximately 7 db) ensures a very fast gain reduction for a large increasing if amplitude step. 8.11 single reference qss mixer with the present system a high performance hi-fi stereo sound processing can be achieved. for a simplified application without a sif saw filter, the single reference qss mixer can be switched to the intercarrier mode via the i 2 c-bus. the single reference qss mixer generates the 2nd fm tv sound intercarrier signal. it is realized by a linear multiplier which multiplies the sif amplifier output signal and the vif-pll vco signal (90 degrees output) which is locked to the picture carrier. in this way the qss mixer operates as a quadrature mixer in the intercarrier mode and provides suppression of the low frequency video signals. the qss mixer output signal is fed internally via a high-pass and low-pass combination to the fm demodulator as well as via an operational amplifier to the intercarrier output pin siomad. 8.12 am demodulator the amplitude modulated sif amplifier output signal is fed both to a two-stage limiting amplifier that removes the am and to a linear multiplier. the result of the multiplication of the sif signal with the limiter output signal is am demodulation (passive synchronous demodulator). the demodulator output signal is fed via a low-pass filter that attenuates the carrier harmonics and via the input amplifier of the sif-agc detector to the audio amplifier. 8.13 fm demodulator and acquisition help the narrow-band fm-pll detector consists of: gain controlled fm amplifier and agc detector narrow-band pll. the intercarrier signal from the intercarrier mixer or from pin fmin is fed to the input of an ac-coupled gain controlled amplifier with two stages. the gain controlled output signal is fed to the phase detector of the narrow-band fm-pll (fm demodulator). for good selectivity and robustness against disturbance caused by the video signal, a high linearity of the gain controlled fm amplifier and of the phase detector as well as a constant signal level are required. the gain control is done by means of an in phase demodulator for the fm carrier (from the output of the fm amplifier). the demodulation output is fed into a comparator for charging or discharging the integrated agc capacitor. this leads to a mean value agc loop to control the gain of the fm amplifier. the fm demodulator is realized as a narrow-band pll with an external loop filter, which provides the necessary selectivity (bandwidth approximately 100 khz). to achieve good selectivity, a linear phase detector and a constant input level are required. the gain controlled intercarrier signal from the fm amplifier is fed to the phase detector. the phase detector controls via the loop filter the integrated low radiation relaxation oscillator. the designed frequency range is from 4 to 7 mhz. the vco within the fm-pll is phase-locked to the incoming 2nd sif signal, which is frequency modulated. as well as this, the vco control voltage is superimposed by the af voltage. therefore, the vco tracks with the fm of the 2nd sif signal. so, the af voltage is present at the loop filter and is typically 5 mv (rms) for 27 khz fm deviation. this af signal is fed via a buffer to the audio amplifier. the correct locking of the pll is supported by the digital acquisition help circuit (see section 8.6).
2004 aug 25 13 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 8.14 audio ampli?er and mute time constant the audio amplifier consists of two parts: af preamplifier af output amplifier. the af preamplifier used for fm sound is an operational amplifier with internal feedback, high gain and high common mode rejection. the af voltage from the pll demodulator is 5 mv (rms) for a frequency deviation of 27 khz and is amplified by 30 db. by the use of a dc operating point control circuit (with external capacitor c af ), the af preamplifier is decoupled from the pll dc voltage. the low-pass characteristic of the amplifier reduces the harmonics of the sound intercarrier signal at the af output terminal. for fm sound a switchable de-emphasis network (with external capacitor) is implemented between the preamplifier and the output amplifier. the af output amplifier provides the required af output level by a rail-to-rail output stage. a preceding stage makes use of an input selector for switching between fm sound, am sound and mute state. the gain can be switched between 10 db (normal) and 4 db (reduced). switching to the mute state is controlled automatically, dependent on the digital acquisition help in case the vco of the fm-pll is not in the required frequency window. this is done by a time constant: fast for switching to the mute state and slow (typically 40 ms) for switching to the no-mute state. all switching functions are controlled via the i 2 c-bus: am sound, fm sound and forced mute auto mute enable or disable de-emphasis off or on with 50 or 75 m s audio gain normal or reduced. 8.15 radio mode the principle is to multiply the first radio if (e.g. 33.3 mhz at tuner output) with 44 mhz reference signal. the result of the down-conversion is the second radio if (10.7 mhz) at intercarrier output. in the radio mode the tuner delivers a first radio if signal of 33.3 mhz. this signal is fed via the sif saw filter (conventional used for qss tv sound processing) to the sif input. the sound if amplifier supplies this radio if signal by means of gain control with constant level to the qss mixer. the single reference qss mixer generates the second radio if signal of 10.7 mhz. in the radio mode the vif vco operates as part of a frequency synthesizer and delivers a constant 44 mhz signal (derived from the reference signal of 4 mhz) for the down-conversion of the first radio if to 10.7 mhz. this signal is fed via the external ceramic band-pass filter to the fm demodulator. the demodulated af signal is amplified by the audio amplifier. in case of ntsc application (m/n standard) the internal mixing frequency is 52 mhz. so, the first radio if has to be 41.3 mhz. in the radio mode, the tuner agc is derived from the sif-agc. for tuning search mode, the device offers certain monitoring functions. switchable are radio afc, fm-agc or sif-agc to pin afc. 8.16 internal voltage stabilizer the band gap circuit internally generates a voltage of approximately 2.4 v, independent of supply voltage and temperature. a voltage regulator circuit, connected to this voltage, produces a constant voltage of 3.55 v which is used as an internal reference voltage. 8.17 i 2 c-bus transceiver and module address the device can be controlled via the 2-wire i 2 c-bus by a microcontroller. two wires carry serial data (sda) and serial clock (scl) information between the devices connected to the i 2 c-bus. the device has an i 2 c-bus slave transceiver with auto-increment. the circuit operates up to clock frequencies of 400 khz. a slave address is sent from the master to the slave receiver. to avoid conflicts in a real application with other devices providing similar or complementing functions, there are four possible slave addresses available. these module addresses (mads) can be selected by connecting resistors on pin siomad and/or pins sif1 and sif2 (see fig.25). pin siomad relates with bit a0 and pins sif1 and sif2 relate with bit a3. the slave addresses of this device are given in table 1. the power-on preset value is dependent on the use of pin siomad and can be chosen for 45.75 mhz ntsc as default (pin siomad left open-circuit) or 58.75 mhz ntsc (resistor on pin siomad). in this way the device can be used without the i 2 c-bus as an ntsc only device. remark: in case of using the device without the i 2 c-bus, then the rise time of the supply voltage after switching on power must be longer than 1.2 m s.

2004 aug 25 37 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 22. calculation of the loop filter parameters can be done approximately using the following formulae: the formulae are only valid under the following conditions: j 1 and c s >5c p where: k o is the vco steepness or ; k d is the phase detector steepness ; r is the loop resistor; c s is the series capacitor; c p is the parallel capacitor; f o is the natural frequency of the pll; bl - 3db is the loop bandwidth for - 3 db; j is the damping factor. for examples, see table 20. 23. the pc/sc ratio is calculated as the addition of tv transmitter pc/sc 1 ratio and saw filter pc/sc 1 ratio. this pc/sc ratio is necessary to achieve the s/n w values as noted. a different pc/sc ratio will change these values. 24. measurements taken with saw filter g1984 (siemens) for vision and sound if (sound shelf: 14 db). picture-to-sound carrier ratio of transmitter pc/sc = 13 db. input level on pins vif1 and vif2 of v i(sif) = 10 mv (rms) sync level, 27 khz fm deviation for sound carrier, f af = 400 hz. measurements in accordance with ccir 468 . de-emphasis is 50 m s. 25. the qss signal output on pin siomad is analysed by a test demodulator tda9820. the s/n ratio of this device is more than 60 db, related to a deviation of 27 khz, in accordance with ccir 468 . 26. measurements taken with saw filter k3953 for vision if (suppressed sound carrier) and k9453 for sound if (suppressed picture carrier). input level v i(sif) = 10 mv (rms), 27 khz (54 % fm deviation). 27. measurements taken with saw filter k9453 (siemens) for am sound if (suppressed picture carrier). 28. the value of c x determines the accuracy of the resonance frequency of the crystal. it depends on the type of crystal used. 29. pin ref is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from the tuning system. 30. the sda and scl lines will not be pulled down if v cc is switched off. 31. the ac characteristics are in accordance with the i 2 c-bus specification for fast mode (maximum clock frequency is 400 khz). information about the i 2 c-bus can be found in the brochure the i 2 c-bus and how to use it (order number 9398 393 40011). 32. port p1 and port p2 are open-collector outputs. f o 1 2 p ------ - k o k d c p --------------- = j 1 2r k o k d c p ------------------------------------ = bl 3db C f o 1.55 j 2 C () = rad v -------- ? ?? 2 p hz v ------ - ? ?? m a rad -------- ? ??

2004 aug 25 54 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 15 soldering 15.1 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. 15.2 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. 15.3 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. 15.4 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 aug 25 55 philips semiconductors product speci?cation i 2 c-bus controlled multistandard alignment-free if-pll demodulator with fm radio tda9887 15.5 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, 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. 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 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, uson, vfbga not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable (4) suitable plcc (5) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (5)(6) suitable ssop, tssop, vso, vssop not recommended (7) suitable cwqccn..l (8) , pmfp (9) , wqccn..l (8) not suitable not suitable
