FUNCTIONAL DESCRIPTION 3-stage IF amplifier The VIF amplifier consists of three AC-coupled differential amplifier stages (see Fig.1). Each differential stage comprises a feedback network controlled by emitter degeneration. The VCO signal is divided-by-2 with a Travelling Wave Divider (TWD) which generates two differential output signals with a 90 degree phase difference independent of the frequency. AGC detector, IF AGC and tuner AGC Video amplifier The automatic control voltage to maintain the video output signal at a constant level is generated in accordance with the transmission standard. Since the TDA9801(T) is suitable for negative modulation only the peak sync pulse level is detected. The composite video amplifier is a wide bandwidth operational amplifier with internal feedback. A nominal positive video signal of 1 V (p-p) is present at pin VSO. Buffer amplifier and noise clipper The AGC detector charges and discharges capacitor CAGC to set the IF amplifier and tuner gain. The voltage on capacitor CAGC is transferred to an internal IF control signal, and is fed to the tuner AGC to generate the tuner AGC output current on pin TAGC (open-collector output). The tuner AGC takeover point level is set at pin TOP. This allows the tuner to be matched to the SAW filter in order to achieve the optimum IF input level. The input impedance of the 7 dB wideband CVBS buffer amplifier (with internal feedback) is suitable for ceramic sound trap filters. Pin CVBS provides a positive video signal of 2 V (p-p). Noise clipping is provided internally. Sound demodulation LIMITER AMPLIFIER The FM sound intercarrier signal is fed to pin SI and through a limiter amplifier before it is demodulated. The result is high sensitivity and AM suppression. The limiter amplifier consists of 7 stages which are internally AC-coupled in order to minimizing the DC offset. Frequency detector and phase detector The VIF amplifier output signal is fed into a frequency detector and into a phase detector. During acquisition the frequency detector produces a DC current proportional to the frequency difference between the input and the VCO signal. After frequency lock-in the phase detector produces a DC current proportional to the phase difference between the VCO and the input signal. The DC current of either frequency detector or phase detector is converted into a DC voltage via the loop filter which controls the VCO frequency. FM-PLL DETECTOR The FM-PLL demodulator consists of an RC oscillator, loop filter and phase detector. The oscillator frequency is locked on the FM intercarrier signal from the limiter amplifier. As a result of this locking, the RC oscillator is frequency modulated. The modulating voltage (AF signal) is used to control the oscillator frequency. By this, the FM-PLL operates as an FM demodulator. Video demodulator The true synchronous video demodulator is realized by a linear multiplier which is designed for low distortion and wide bandwidth. The vision IF input signal is multiplied with the ‘in phase’ component of the VCO output. The demodulator output signal is fed via an integrated low-pass filter (fg = 12 MHz) for suppression of the carrier harmonics to the video amplifier. AF AMPLIFIER The audio frequency amplifier with internal feedback is designed for high gain and high common-mode rejection. The low-level AF signal output from the FM-PLL demodulator is amplified and buffered in a low-ohmic audio output stage. An external decoupling capacitor CDAF removes the DC voltage from the audio amplifier input. VCO, AFC detector and travelling wave divider By using the sound mute switch (pin MUTE) the AF amplifier is set in the mute state. The VCO operates with a symmetrically connected reference LC circuit, operating at the double vision carrier frequency. Frequency control is performed by an internal variable capacitor diode. 1999 Aug 26 TDA9801 6 Philips Semiconductors Product specification Single standard VIF-PLL demodulator and FM-PLL detector TDA9801 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

Values of video and sound parameters can be decreased at VP = 4.5 V. 2. This parameter is not tested during production and is only given as application information for designing the television receiver. 3. Conditions for video demodulator: a) Loop bandwidth: BL = 60 kHz, natural frequency fn = 15 kHz, damping factor d = 2, calculated with grey level and FPLL input level b) Resonance circuit of VCO: Qo > 50, see Table 2 for the value of the external capacitor C; CVCO = 8.5 pF, loop voltage is approximately 2.6 V at VP = 5 V and approximately 2.7 V at VP = 9 V. 4. Temperature coefficient of the external LC circuit is equal to zero. 5. Vi(VIF)(rms) = 10 mV; ∆f = 1 MHz (VCO frequency offset related to fPC); white picture video modulation. 6. Vi(VIF) signal for nominal video signal. 7. Broadband transformer at the VIF input (see Fig.12). The C/N ratio at the VIF input for ‘lock-in’ is defined as the VIF input signal (RMS value of sync pulse level) related to a superimposed 5 MHz band-limited white noise signal (RMS value). The video modulation is for white picture. 8. The offset current is measured between pin TPLL and half of the supply voltage (VP = 2.5 V) under the conditions: a) no input signal at VIF inputs b) IF amplifier gain at minimum (VAGC = VP) and pin ADJ is left open-circuit. 9. The intercarrier output signal is superimposed to the video signal at pin VSO and can be calculated by the following formula: 1 V o(intc)(rms) = 1.0 V (p-p) × ----------- × 10 2 2 where V i(SC) --------------- (dB) + 6 dB ± 2 dB V i(PC) -----------------------------------------------------------------20 a) 1.0 V (p-p) = video output signal as reference 1 b) ----------- = correction term for RMS value 2 2 V i(SC) c) --------------- (dB) = sound-to-picture carrier ratio at VIF inputs in dB V i(PC) d) 6 dB = correction term of internal circuitry e) ±2 dB = tolerance of video output and intercarrier output amplitude Vo(intc)(rms). f) Example for SAW filter G1962: sound shelf value = 20 dB, V i(SC) --------------- = – 27 dB ⇒ V o(intc)(rms) = 32 mV (typical value) V i(PC) 1999 Aug 26 13 Philips Semiconductors Product specification Single standard VIF-PLL demodulator and FM-PLL detector TDA9801 10. Measurements taken with SAW filter G1962; VSB modulation; fvideo > 0.5 MHz; loop bandwidth BL = 60 kHz. 11. The 7 dB buffer amplifier gain accounts for 1 dB loss in the sound trap. The buffer output signal is typical 2 V (p-p). If no sound trap is applied a resistor of 330 Ω must be connected between pins VSO and VI. 12. The leakage current of CAGC should not exceed 1 µA. Larger currents will increase the tilt. 13. S/N is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value) at pin CVBS. B = 5 MHz weighted in accordance with “CCIR 567” at a source impedance of 50 Ω. 14. The intermodulation figures are defined: V o at 4.4 (3.58) MHz a) α IM ( 0.92 ⁄ 1.1 ) = 20 log ------------------------------------------------------- + 3.6 dB V o at 0.92 (1.1) MHz αIM(0.92/1.1) value at 0.92 (or 1.1) MHz referenced to black or white signal V o at 4.4 (3.58) MHz b) α IM ( 2.76 ⁄ 3.3 ) = 20 log ------------------------------------------------------- V o at 2.76 (3.3) MHz αIM(2.76/3.3) value at 2.76 (or 3.3) MHz referenced to colour carrier. 15. To match the AFC output signal to different tuning systems a current source output is provided (see Fig.8). 16. The no mute state is also valid when pin MUTE is not connected. 17. The input signal is provided by an external generator with 50 Ω source impedance, AC-coupled with a 10 nF capacitor, fmod = 1 kHz and 27 kHz (54% FM deviation) of audio reference. A VIF input signal is not permitted. Pin AGC has to be connected to the supply voltage. Measurements are taken at 50 µs de-emphasis (75 µs at the M standard). 18. To allow a higher frequency deviation, the value of resistor R3 on pin DAF (see Fig.13) has to be increased. However, the AF output signal must not exceed 0.5 V (nominal value) for THD = 0.2%. R3 = 4.7 kΩ provides −6 dB amplification. 19. The leakage current of the 2.2 µF decoupling capacitor should not exceed 100 nA. 20.

The top-surface temperature of the packages should preferable be kept below 230 °C. SOLDERING Introduction 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). 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. There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mount components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 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. Through-hole mount packages SOLDERING BY DIPPING OR BY SOLDER WAVE • For packages with leads on two sides and a pitch (e): The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joints for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. – 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; – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 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. MANUAL SOLDERING Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. 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. Surface mount packages REFLOW SOLDERING MANUAL 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. 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. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. 1999 Aug 26 TDA9801 When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. 30 Philips Semiconductors Product specification Single standard VIF-PLL demodulator and FM-PLL detector TDA9801 Suitability of IC packages for wave, reflow and dipping soldering methods SOLDERING METHOD MOUNTING PACKAGE WAVE suitable(2) Through-hole mount DBS, DIP, HDIP, SDIP, SIL Surface mount REFLOW(1) DIPPING − suitable BGA, SQFP not suitable suitable − HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, SMS not suitable(3) suitable − PLCC(4), SO, SOJ suitable suitable − suitable − suitable − recommended(4)(5) LQFP, QFP, TQFP not SSOP, TSSOP, VSO not recommended(6) Notes 1. 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”. 2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. 3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 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 only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or 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 only 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.
