Gain control is performed by emitter degeneration. The total gain control range is typical 66 dB. The differential input impedance is typical 2 kΩ in parallel with 3 pF. 8.2 Tuner AGC and VIF AGC This block adapts the voltage, generated at the VIF AGC detector, to the internal signal processing at the VIF amplifier and performs the tuner AGC control current generation. The onset of the tuner AGC control current generation can be set by a potentiometer at pin TOP. 8.3 VIF AGC detector Gain control is performed using sync level detection. The sync level voltage is stored in 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 to generate the 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’. 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004.

Rev. 01 — 16 November 2004 7 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator 8.4 FPLL detector The VIF amplifier output signal is fed to a frequency detector and a phase detector via a limiting amplifier to remove the video AM. During acquisition the frequency detector produces a current that is proportional to the frequency difference between the VIF and the VCO signal. After frequency lock-in the phase detector produces a current that is proportional to the phase difference between the VIF and the VCO signal. The currents from the frequency and phase detector are charged into the loop filter which controls the VIF VCO and locks it to the frequency and phase of the VIF carrier. 8.5 VCO and divider The VCO of the VIF FPLL operates as an integrated low radiation relaxation oscillator at twice the picture carrier frequency. The control voltage, required to tune the VCO to actually double the picture carrier frequency, is generated at the loop filter by the frequency phase detector. The possible frequency range is 50 MHz 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 single reference QSS or intercarrier mixer. 8.6 AFC and digital acquisition help circuit Each relaxation oscillator of the VIF PLL and FM PLL demodulator has a wide frequency range. To prevent false locking of the PLLs, with respect to the catching range, the digital acquisition help circuit provides an individual control until the frequency of the VCO is within the preselected standard dependent lock-in window of the PLL. The VIF carrier frequencies 38.0 MHz, 38.9 MHz (M/N, B/G, I and D/K standard) and 45.75 MHz, 58.75 MHz (NTSC standard) can be selected via pin VIF0 and pin QSSO with resistor; see Table 4. The FM carrier frequencies can be selected via pin FM0 and pin FM1; see Table 5. The in-window and out-window control at the FM PLL can additionally be used to mute the audio stage (if auto mute is selected via pin AMUTE0); see Table 6. The principle working of the digital acquisition help circuit is as follows: The PLL VCO output is connected to a downcounter which has a predefined start value (standard dependent). The VCO frequency clocks the downcounter for a fixed gate time. Thereafter, the downcounter stop value is analyzed. In the event that the stop value is higher (lower) than the expected value range, the VCO frequency will be lower (higher) than the required lock-in window frequency range. A positive (negative) control current is injected into the PLL loop filter which causes the VCO frequency to be 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. 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004. All rights reserved. Rev. 01 — 16 November 2004 8 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator The AFC signal is derived from the corresponding downcounter stop value after a counting cycle. The last four bits are latched and the digital-to-analog converted value is given as current at pin AFC. 8.7 Video demodulator and amplifier 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 is 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). Noise clipping is provided. 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. Thus 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 carrier. 8.9 SIF amplifier The SIF amplifier consists of three AC-coupled differential stages. Gain control is performed by emitter degeneration. The total gain control range is typical 66 dB. The differential input impedance is typical 2 kΩ in parallel with 3 pF. 8.10 SIF AGC detector SIF gain control is performed by the detection of the SIF voltage at the output of the SIF amplifier so that a constant SIF signal is supplied to the single reference QSS mixer. For an optimum adaption between the SIF AGC and the VIF AGC characteristics at 13 dB picture-to-sound FM carrier ratio, the internal SIF level is reduced. The integrated AGC capacitor is charged or discharged for the generation of the required SIF gain via a comparator. An additional circuit (threshold approximately 7 dB) ensures a very fast gain reduction for a large increasing IF amplitude step. 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004.

Rev. 01 — 16 November 2004 9 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator 8.11 Single reference QSS mixer With the present system high performance Hi-Fi stereo sound processing can be achieved. For a simplified application without an SIF SAW filter, the single reference QSS mixer can be switched to the intercarrier mode via pins SIF1 and SIF2; see Table 7. 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 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 QSS output pin QSSO. 8.12 FM demodulator and acquisition help circuit The narrow-band FM PLL detector consists of: • Gain controlled FM amplifier and AGC detector • Narrow-band PLL. The intercarrier signal from the single reference QSS mixer 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 MHz to 7 MHz. The VCO within the FM PLL is phase-locked to the incoming 2nd SIF signal which is frequency modulated. The VCO control voltage is superimposed by the AF voltage. Therefore, the VCO tracks with the FM of the 2nd SIF signal. Thus, 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. 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004.

Rev. 01 — 16 November 2004 10 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator 8.13 Audio amplifier 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 using a DC operating point control circuit (with external capacitor CAF), 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 de-emphasis time constant with 50 µs or 75 µs depends on the FM carrier selection via pins FM0 and FM1; see Table 5. 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 the FM sound and mute state. Switching to the mute state is controlled automatically, depending on the digital acquisition help circuit should the VCO of the FM PLL not be 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 non-mute state. Auto mute can be disabled via pin AMUTE0; see Table 6. 8.14 Internal voltage stabilizer The band gap circuit internally generates a voltage of approximately 2.4 V, independent of the supply voltage and the 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. 8.15 Logic The logic circuit detects the logic level at the logic ports VIF0, QSSO, FM0, FM1 and AMUTE0 and controls the internal functions; see Table 4 to Table 6. In the event that all logic ports are open-circuit (high-ohmic or CMOS HIGH level) TV standard NTSC with a vision carrier frequency of 45.75 MHz, an FM sound carrier frequency of 4.5 MHz, de-emphasis with 75 µs time constant and auto mute on is selected.

Rev. 01 — 16 November 2004 22 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator [2] Level headroom for input level jumps during gain control setting. [3] This parameter is not tested during the production and is only given as application information for designing the receiver circuit. [4] Loop bandwidth BL = 70 kHz (damping factor d = 1.9; calculated with sync level within gain control range). Calculation of the VIF PLL filter can be done by use of the following formula: 1 BL – 3dB = ------K O K D R , valid for d ≥ 1.2 2π 1 d = --- R K O K D C , 2 where: Hz µA rad KO is the VCO steepness ------- or 2π ------- ; KD is the phase detector steepness ------- ; V V rad R is the loop resistor; C is the loop capacitor; BL−3dB is the loop bandwidth for −3 dB; d is the damping factor. [5] Vi(VIF) = 10 mV (RMS); ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video modulation. [6] Condition: luminance range (5 steps) from 0 % to 100 %. [7] S/NW(video) is the ratio of black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS). B = 5 MHz (B/G, I and D/K standard). Noise analyzer setting: 200 kHz high-pass and SC-trap switched on. [8] The intermodulation figures are defined for: V 0 at 4.4 MHz a) f = 1.1 MHz (referenced to black and white signal) as α IM = 20 log ----------------------------------- + 3.6 dB V at 1.1 MHz 0 V 0 at 4.4 MHz b) f = 3.3 MHz (referenced to color carrier) as α IM = 20 log ----------------------------------- V at 3.3 MHz 0 [9] Modulation Vestigial Side-Band (VSB); sound carrier off; fvideo > 0.5 MHz. Measurements taken with SAW filter M1963M (sound shelf: 20 dB); loop bandwidth BL = 70 kHz. [10] Sound carrier on; fvideo = 10 kHz to 10 MHz. Measurements taken with SAW filter M1963M (sound shelf: 20 dB); loop bandwidth BL = 70 kHz. [11] Conditions: video signal, grey level and negative modulation. [12] AC load; CL < 20 pF and RL > 1 kΩ. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps (see Figure 12 to Figure 17; H(s) is the absolute value of transfer function). [13] The response time is valid for a VIF input level range from 200 µV to 70 mV. [14] To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is given in Figure 9. The AFC slope (voltage per frequency) can be changed by resistors R1 and R2. [15] The tolerance of the reference frequency determines the accuracy of the VIF AFC, FM demodulator center frequency and maximum FM deviation. [16] The intercarrier output signal at pin QSSO can be calculated by the following formula taking into account the internal video signal with 1.1 V (p-p) as a reference: 1 V o(intc) = 1.1 V (p-p) × ---------- × 10 2 2 1 V i ( SC ) ----------------- ( dB ) + 6 dB ± 3 dB V i ( PC ) ----------------------------------------------------------------20 (RMS) V i ( SC ) V i ( PC ) where: ---------- is the correction term for RMS value, ---------------- ( dB ) is the sound-to-picture carrier ratio at pins VIF1 and VIF2 in dB, 6 dB is 2 2 the correction term of internal circuitry and ± 3 dB is the tolerance of video output and intercarrier output Vo(intc)(rms). [17] To detect a logical 1 at pin QSSO, no DC load at pin QSSO is allowed. QSSO = 0 will be done by the application of a 2.2 kΩ resistor between pin QSSO and ground. [18] SIF input level is 10 mV (RMS); VIF input level is 10 mV (RMS) unmodulated. [19] Measured with an FM deviation of 25 kHz and the typical AF output voltage of 500 mV (RMS). For handling a frequency deviation of more than 55 kHz, the AF output signal has to be reduced in order to avoid clipping (THD < 1.5 %) by means of a resistor Rx with external application at pin AFD (see Figure 20 and Figure 21). [20] The lower limit of the audio bandwidth depends on the value of the capacitor at pin AFD. A value of CAF = 470 nF leads to fAF(−3dB) ≈ 20 Hz and CAF = 220 nF leads to fAF(−3dB) ≈ 40 Hz. 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004. All rights reserved. Rev. 01 — 16 November 2004 23 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator [21] For all S/N measurements the used VIF modulator has to meet the following specifications: a) Incidental phase modulation for black-to-white jump less than 0.5 degrees. b) QSS AF performance, measured with the television demodulator AMF2 (audio output, weighted S/N ratio) better than 60 dB (at deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation. c) Picture-to-sound carrier ratio PC/SC1 = 13 dB (transmitter). [22] Calculation of the loop filter can be done approximately by use of the following formulae: 1 K OK D f o = ------ ---------------CP 2π 1 ϑ = ----------------------------------2R K O K D C P 2 BL – 3dB = f o ( 1.55 – ϑ ) The formulae are only valid under the following conditions: ϑ ≤ 1 and CS > 5CP rad Hz µA where: KO is the VCO steepness ------- or 2π ------- ; KD is the phase detector steepness ------- ; R is the loop resistor; CS is the series V V rad capacitor; CP is the parallel capacitor; fo is the natural frequency of PLL; BL−3dB is the loop bandwidth for −3 dB; ϑ is the damping factor. For examples, see Table 11. [23] The PC/SC ratio is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This PC/SC ratio is necessary to achieve the S/NW 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 Vi(SIF) = 10 mV (RMS) sync level, 27 kHz FM deviation for sound carrier, fAF = 400 Hz. Measurements in accordance with “CCIR 468”. De-emphasis is 50 µs. [25] The QSS signal output on pin QSSO is analyzed 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 G3962 for vision IF (suppressed sound carrier) and K9350 for sound IF (suppressed picture carrier). Input level Vi(SIF) = 10 mV (RMS), 27 kHz (54 % FM deviation). [27] The value of Cx determines the accuracy of the resonance frequency of the crystal. It depends on the used type of crystal. [28] 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.

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 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. 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) – for all BGA, HTSSON..T and SSOP..T packages – for packages with a thickness ≥ 2.5 mm – for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 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 mm3 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): – 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; 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004. All rights reserved. Rev. 01 — 16 November 2004 37 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator – 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. 15.5 Package related soldering information Table 13: Suitability of surface mount IC packages for wave and reflow soldering methods Package [1] Soldering method Wave Reflow [2] BGA, HTSSON..T [3], LBGA, LFBGA, SQFP, SSOP..T [3], TFBGA, VFBGA, XSON 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 not recommended [5] [6] suitable SSOP, TSSOP, VSO, VSSOP not recommended [7] suitable CWQCCN..L [8], PMFP [9], WQCCN..L [8] not suitable LQFP, QFP, TQFP [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. 9397 750 13417 Product data sheet not suitable © Koninklijke Philips Electronics N.V. 2004. All rights reserved. Rev. 01 — 16 November 2004 38 of 42 TDA9881 Philips Semiconductors Alignment-free vision and FM sound IF PLL demodulator [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. 9397 750 13417 Product data sheet © Koninklijke Philips Electronics N.V. 2004. All rights reserved.
