[2] AC load; CL < 20 pF and RL > 1 k. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps. [3] Condition: luminance range (5 steps) from 0 % to 100 %. Measurement value is based on 4 of 5 steps. [4] The sound carrier trap can be bypassed by setting the I2C-bus bit W2[0] to logic 0; see Table 23. In this way the full composite video spectrum appears at pin CVBS. The video amplitude is reduced to 1.1 V (p-p). [5] Measurement using 200 kHz high-pass filter, 5 MHz low-pass filter and subcarrier notch filter ("ITU-T J.64"). [6] To match the AFC output signal to different tuning systems a current output is provided. The test circuit is given in Figure 19. The AFC steepness can be changed by resistors R1 and R2. [7] With single-ended load for fIF < 45 MHz RL 1 k and CL 5 pF to ground and for fIF = 45 MHz to 60 MHz RL = 1 k and CL 3 pF to ground. [8] This parameter is not tested during production and is only given as application information. [9] Noise level is measured without input signal but AGC adjusted corresponding to the given input level. [10] Set with AGC nominal output voltage as reference. For C/N measurement switch input signal off. [11] The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum FM deviation, sound trap frequency, LIF band-pass cut-off frequency, as well as the accuracy of the synthesizer.

Functional description 8.1 IF input switch Different signal bandwidth can be handled by using two signal processing chains with individual gain control. Switch configuration allows independent selection of filter for analog VIF and for analog SIF (used at same time) or DIF. The switch takes into account correct signal selection for TAGC in the event of VIF and DIF signal processing. 8.2 VIF demodulator ATV demodulation using 6 MHz DVB window (band-pass) filter (for 6 MHz, 7 MHz or 8 MHz channel width). IF frequencies adapted to enable the use of different filter configurations. The Nyquist processing is integrated. The integrated Nyquist processing provides also adjacent channel suppression. Sideband switch supplies selection of lower or upper sideband (e.g. for L-accent). For optional use of standard Nyquist filter the integrated Nyquist processing can be switched off. Equalizer provides optimum pulse response at different standards [e.g. to cope with higher demands for Liquid Crystal Display (LCD) TV]. Integrated sound traps. Sound trap reference independent from received 2nd sound IF (reference taken from integrated reference synthesizer). IF level selection provides an optimum adaptation of the demodulator to high linearity or low noise. 8.3 VIF AGC and tuner AGC 8.3.1 Mode selection of VIF AGC Peak white AGC for positive modulation mode with adaptation for speed up and black level AGC (using proven system from TDA9886). For negative modulation mode equal response times for increasing or decreasing input level (optimum for amplitude fading) or normal peak AGC or ultra fast peak AGC. 8.3.2 VIF AGC monitor VIF AGC DC voltage monitor output (with expanded internal characteristic). VIF AGC read out via I2C-bus (for IF level indication) with zero-calibration via TOP setting (TOP setting either via I2C-bus or via TOP potentiometer).

Rev. 04 -- 25 May 2009 15 of 103 TDA9897; TDA9898 NXP Semiconductors Multistandard hybrid IF processing 8.3.3 Tuner AGC Independent integral tuner gain control loop (not nested with VIF AGC). Integral characteristic provides high control accuracy. Accurate setting of tuner control onset (TOP) for integral tuner gain control loop via I2C-bus. For L standard, TAGC remains VIF AGC nested, as from field experience in the past this narrowband TAGC gives best performance. Thus two switchable TAGC systems for negative/DIF and positive modulation implemented. L standard tuner time constant switching integrated (= speed up function in the event of step into high input levels), to speed up settling time. For TOP setting at L standard, additional adjustment via optional potentiometer or I2C-bus is provided. Tuner AGC status bit provided. 8.4 DIF/SIF FM and AM sound AGC External AGC control input for DIF. DIF includes direct IF and low IF. Integrated gain control loop for SIF. AGC control for FM SIF related to used SAW bandwidth. Peak AGC control in the event of FM SIF. Ultra fast SIF AGC time constant when VIF AGC set to ultra fast mode. Slow average AGC control in the event of AM sound. AM sound AGC related to AM sound carrier level. Fast AM sound AGC in the event of fast VIF AGC (speed up). SIF/FM AGC DC voltage monitor output with expanded internal characteristic. 8.5 Frequency phase-locked loop for VIF Basic function as previous TDA9887 design. PLL gating mode for positive and negative modulation, optional. PLL optimized for either overmodulation or strong multipath. TDA9897_TDA9898_4 Product data sheet (c) NXP B.V. 2009.

Rev. 04 -- 25 May 2009 16 of 103 TDA9897; TDA9898 NXP Semiconductors Multistandard hybrid IF processing 8.6 DIF/SIF converter stage Frequency conversion with sideband suppression. Selection mode of upper or lower sideband for pass or suppression. Suppression around zero for frequency conversion. Conversion mode selection via synthesizer for DIF and radio mode or via VIF Frequency Phase-Locked Loop (FPLL) for TV QSS sound (FM/AM). External BP filter (e.g. for 4.5 MHz) for additional filtering, optional. Bypass mode selection for use of external filter. Integrated SIF BP tracking filter for chroma suppression. Integrated tracking filters for LIF. Symmetrical output stages for direct IF, LIF and 2nd SIF (intercarrier signal). Second narrowband gain control loop for 2nd SIF via FM PLL. 8.7 Mono sound demodulator 8.7.1 FM PLL narrowband demodulation Additional external input for either TV or radio intercarrier signal. FM carrier selection independent from VIF trap, because VIF trap uses reference via synthesizer. FM wide and ultra wide mode with adapted loop bandwidth and different selectable FM acquisition window widths to cope with FM overmodulation conditions. 8.7.2 AM sound demodulation AM sound envelope detector. L and L-accent standard without SAW switching (done by sideband selection of SIF converter). 8.8 Audio amplifier Different gain settings for FM sound to adapt to different FM deviation. Switchable de-emphasis for FM sound. Automatic mute function when FM PLL is unlocked. Forced mute function. Output amplifier for AM sound. TDA9897_TDA9898_4 Product data sheet (c) NXP B.V. 2009. All rights reserved. Rev. 04 -- 25 May 2009 17 of 103 TDA9897; TDA9898 NXP Semiconductors Multistandard hybrid IF processing 8.9 Synthesizer The synthesizer supports SIF/DIF frequency conversion. A large set of synthesizer frequencies in steps of 0.5 MHz enables flexible combination of SAW filter and required conversion frequency. Synthesizer loop internally adapted to divider ratio range for optimum phase noise requirement (loop bandwidth). Synthesizer reference either via 4 MHz crystal or via an external source. Individual pins for crystal and external reference allows optimum interface definition and supports use of custom reference frequency offset. 8.10 I2C-bus transceiver and slave address Four different I2C-bus device addresses to enable application with multi-IC use. I2C-bus transceiver input ports can handle three different I2C-bus voltages. Read-out functions as TDA9887 plus additional read out of VIF AGC and VIFLOCK, BLCKLEV and TAGC status. Table 4.

Rev. 04 -- 25 May 2009 62 of 103 TDA9897; TDA9898 NXP Semiconductors Multistandard hybrid IF processing [5] BLF(-3dB) = 100 kHz (damping factor d = 1.7; calculated with sync level within gain control range). Calculation of the VIF PLL filter by using the following formulae: B LF ( -3dB ) = K O K D R , valid for d 1.2 1 d = --- R 2K O K D C 2 with the following parameters: KO = VCO steepness (Hz/V), KD = phase detector steepness (A/rad), R = loop filter serial resistor (), C = loop filter serial capacitor (F), BLF(-3dB) = -3 dB LF bandwidth (Hz), d = damping factor. [6] The VCO frequency offset related to the PC frequency is set to 1 MHz with white picture video modulation. [7] AC load; CL < 20 pF and RL > 1 k. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps. [8] Condition: luminance range (5 steps) from 0 % to 100 %. Measurement value is based on 4 of 5 steps. [9] Measurement using 200 kHz high-pass filter, 5 MHz low-pass filter and subcarrier notch filter ("ITU-T J.64"). [10] Modulation VSB; sound carrier off; fvideo > 0.5 MHz. [11] Sound carrier on; fvideo = 10 kHz to 10 MHz. [12] The sound carrier trap can be bypassed by setting the I2C-bus bit W2[0] to logic 0; see Table 23. In this way the full composite video spectrum appears at pin CVBS. The video amplitude is reduced to 1.1 V (p-p). [13] Measurement condition: with transformer, transmitter pre-correction on; reference is at 1 MHz. [14] The response time is valid for a VIF input level range from 200 V to 70 mV. [15] AGC response time increased if no AGC event occurs during two lines at minimum. [16] AGC response time increased if video level falls below half of selected level. RL [17] Load applied to output pin causes signal loss. The resulting gain can be calculated by using G v(load) = G v + 20 log -------------------- . R + R O L [18] See Figure 19 to smooth current pulses. [19] To match the AFC output signal to different tuning systems a current output is provided. The test circuit is given in Figure 19. The AFC steepness can be changed by different applications of resistors R1 and R2. [20] The AFC value of the VIF and RIF frequency is generated by using digital counting methods. The used counter resolution is provided with an uncertainty of 1 bit corresponding to 25 kHz. This uncertainty of 25 kHz has to be added to the frequency accuracy parameter. [21] Measured with an FM deviation of 25 kHz and the typical AF output voltage of 500 mV (RMS). The audio signal processing stage provides headroom of 6 dB with THD < 1.5 %. The I2C-bus bits W3[0] and W3[1] control the AF output signal amplitude from 0 dB to -18 dB in steps of -6 dB. Reducing the audio gain for handling a frequency deviation of more than 55 kHz avoids AF output signal clipping. [22] Amplitude response depends on dimensioning of FM PLL loop filter. [23] The lower AF cut-off frequency depends on the value of the capacitor at pin CAF. A value of CAF1 = 470 nF leads to f-3dB(AF)l 20 Hz and CAF1 = 220 nF leads to f-3dB(AF)l 40 Hz. [24] For all signal-to-noise 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 signal-to-noise 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). [25] 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 weighted signal-to-noise values as noted. A different PC / SC ratio will change these values. [26] Measurement condition is SC1 / SC2 7 dB. [27] The differential QSS signal output on pins OUT1A and OUT1B is analyzed by a test demodulator TDA9820. The signal-to-noise ratio of this device is better than 60 dB. The measurement is related to an FM deviation of 27 kHz and in accordance with "ITU-R BS.468-4". TDA9897_TDA9898_4 Product data sheet (c) NXP B.V. 2009. All rights reserved. Rev. 04 -- 25 May 2009 63 of 103 TDA9897; TDA9898 NXP Semiconductors Multistandard hybrid IF processing [28] The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum FM deviation, sound trap frequency, LIF band-pass cut-off frequency, as well as the accuracy of the synthesizer. [29] The value of Cpull determines the accuracy of the resonance frequency of the crystal. It depends on the used type of crystal. [30] The AC characteristics are in accordance with the I2C-bus specification for fast mode (maximum clock frequency is 400 kHz). Information about the I2C-bus can be found in the brochure "The I2C-bus and how to use it" (order number 9398 393 40011). [31] The SDA and SCL lines will not be pulled down if VP is switched off. [32] The threshold is dependent on VP. [33] The threshold is independent of VP. Table 54.

[2] This parameter is not tested during production and is only given as application information. [3] Output current can be increased by application of single-ended resistor from each output pin to GND. Recommended resistor value is minimum 1 k. [4] With single-ended load for fIF < 45 MHz RL 1 k and CL 5 pF to ground and for fIF = 45 MHz to 60 MHz RL = 1 k and CL 3 pF to ground. [5] Noise level is measured without input signal but AGC adjusted corresponding to the given input level. [6] Set with AGC nominal output voltage as reference. For C/N measurement switch input signal off. [7] With single-ended load RL 1 k and CL 5 pF to ground. [8] The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum FM deviation, sound trap frequency, LIF band-pass cut-off frequency, as well as the accuracy of the synthesizer. [9] The value of Cpull determines the accuracy of the resonance frequency of the crystal. It depends on the used type of crystal. Table 57.

Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". 16.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 16.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: * Through-hole components * Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: * * * * * * Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 16.3 Wave soldering Key characteristics in wave soldering are: * Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave * Solder bath specifications, including temperature and impurities TDA9897_TDA9898_4 Product data sheet (c) NXP B.V. 2009. All rights reserved. Rev. 04 -- 25 May 2009 97 of 103 TDA9897; TDA9898 NXP Semiconductors Multistandard hybrid IF processing 16.4 Reflow soldering Key characteristics in reflow soldering are: * Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 54) than a SnPb process, thus reducing the process window * Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board * Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 58 and 59 Table 58.

Soldering of through-hole mount packages 17.1 Introduction to soldering through-hole mount packages This text gives a very brief insight into wave, dip and manual soldering. Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. 17.2 Soldering by dipping or by solder wave Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. 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. The total contact time of successive solder waves must not exceed 5 seconds. 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. 17.3 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 C and 400 C, contact may be up to 5 seconds.
