TV and VTR stereo/dual sound processor with digital identification and I2C-bus control
FUNCTIONAL DESCRIPTION The TDA9840 (see Fig.1) receives the signals from the FM-demodulators in a TV two sound-carrier system. The circuit is realized by the H00485 bipolar process. The IC is intended for use in economic TV and VTR receivers. Therefore optimum relationship between integration of functions and use of external components has been striven for. Additionally a new type of identification circuit has been developed. AF signal handling The input AF signals, derived from the two sound carriers, are processed in analog form using operational amplifiers.The circuit incorporates level- and stereo-adjustment to correct the spreading in the FM detector output levels. Dematrixing uses the technique of two amplifiers processing the AF signals. Finally, a source selector provides the facility to route the mono signal through to the outputs (`forced mono'). De-emphasis is performed by two RC low-pass filter networks with internal resistors and external capacitors. This provides a frequency response with the tolerances given in Fig.4. A source selector, controlled via the I2C-bus, allows selection of the different modes of operation in accordance with the transmitted signal. The device was designed for a nominal input signal (FM: 54% modulation is equivalent to f = 27 kHz / AM: m = 0.54) of 250 mV RMS (Vi 1, Vi 2), respectively 500 mV RMS (Vi 3,Vi 4). A nominal gain of 6 dB for Vi 1 and Vi 2 signals and 0 dB for Vi 3 and Vi 4 signals is built-in. By using rail-to-rail operational amplifiers, the clipping level (THD 1.5%) is 1.6 V RMS for VP = 5 V and 2.65 V RMS for VP = 8 V at outputs Vo 1, Vo 2,Vo 3 and Vo 4. Care has been taken to minimize switching plops. Also total harmonic distortion and random noise are considerably reduced. Identification The pilot signal is fed via an external RC high-pass filter and single tuned LC band-pass filter to the input of a gain controlled amplifier. The external LC band-pass filter in combination with the external RC high-pass filter should have a loaded Q-factor of about 40 to 50 to ensure the highest identification sensitivity. By using a fixed coil (5%) to save the alignment (see Fig.2), a Q-factor of about 12 is proposed. This may cause a loss in sensitivity of about 2 to 3 dB. A digital PLL circuit generates a reference carrier, which is synchronized with the pilot carrier. This reference carrier and the gain controlled pilot signal
TDA9840
are fed to the AM-synchronous demodulator. The demodulator detects the identification signal, which is fed through a low-pass filter with external capacitor CLP (pin 3) to a Schmitt-trigger for pulse shaping and suppression of low level spurious signal components. This is a measure against mis-identification. The identification signal is amplified and fed through an AGC low-pass filter with external capacitor CAGC (pin 2) to obtain the AGC voltage for controlling the gain of the pilot signal amplifier. The identification stages consist of two digital PLL circuits with digital synchronous demodulation and digital integrators to generate the stereo or dual sound identification bits which can be read out via the I2C-bus. A 10 MHz quartz crystal oscillator provides the reference clock frequency. The corresponding detection bandwidth is larger than 50 Hz for the pilot carrier signal, so that fp-variations from the transmitter can be tracked in case of missing synchronisation with the horizontal frequency fH. However the detection bandwidth for the identification signal is made small (approximately 1 Hz) to reduce mis-identification. Figure 2 shows an example of the alignment-free fp band-pass filter. To achieve the required QL of approximately 12, the Q0 at fp of the coil was chosen to be approximately 25 (effective Q0 including PCB influence). Using coils with other Q0, the RC-network (RFP, CFP) has to be adapted accordingly. It is assumed that the loss factor tan of the resonance capacitor is 0.01 at fp. Copper areas under the coil might influence the loaded Q and have to be taken into account. Care has also to be taken in environments with strong magnetic fields when using coils without magnetic shielding. I2C-bus transceiver The complete IC is controlled by a microcomputer via the I2C-bus. The built-in I2C-bus transceiver transmits the identification result to the I2C-bus and receives the control data for the source selector and level control. The I2C-bus protocol is given in Tables 2 to 12 respectively. The data transmission between the microcontroller and the other I2C-bus controlled ICs is not disturbed, when the supply voltage of the TDA9840 is not connected or when powering up or down. Finally, a Schmitt-trigger is built-in the SDA/SCL interface to suppress spikes from the I2C-bus.

Power supply The different supply voltages and currents required for the analog and digital circuits are derived from an internal band-gap reference circuit. The AF reference voltage is 1 V . For a fast setting to 1 V an internal start-up circuit 2P 2P is added. A good ripple rejection is achieved with the external capacitor Cref = 100 F/16 V in conjunction with the high ohmic input of the 12VP pin (pin 6). Additional DC-load on this pin is prohibited. Power-on reset When a power-on reset is activated by switching on the supply voltage or because of a supply voltage breakdown, the 117/274 Hz DPLL, the 117/274 Hz integrator and the registers will be reset. Both AF channels (Main and SCART) are muted. Fast mode / test mode
TDA9840
The TDA9840 has a fast mode (test mode) to reduce the integration time of the 117/274 Hz integrator from approximately 1 to 0.5 s. ESD protection All pins are ESD protected. The protection circuits represent the latest state of the art. Internal circuit The internal pin loading diagram is given in Fig.7.

TV and VTR stereo/dual sound processor with digital identification and I2C-bus control
I2C-BUS PROTOCOL FOR THE TV AND VTR STEREO/DUAL SOUND PROCESSOR TDA9840 The TDA9840 has an I2C-bus interface with five registers: status, test, switch, level and stereo adjustment register controlled by a microcontroller via I2C-bus. The status register can be read and the other registers are write registers. The status byte represents the transmitter status detected by the identification circuit and the power-on reset status. The switch register controls the source selectors of the AF signal part, and the level and stereo adjustment register set the input level and stereo adjustment stage. Additionally, a test register is built-in to reduce the detection time of the identification circuit (test mode, fast mode respectively). I2C-bus transceiver and data-handling (bus specification) The TDA9840 is controlled by a microcomputer via the bidirectional 2-line I2C-bus. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor. Data transfer may be initiated only when the bus is not busy. When the bus is free, both lines are HIGH. The data on the SDA line must be stable during the HIGH period of the clock. The HIGH or LOW state of the data line can only change, when the clock signal on the SCL line is LOW. The set-up and hold times are specified in the Chapter "Characteristics". A HIGH-to-LOW transition of the SDA line, while SCL is HIGH, is defined as the start condition. A LOW-to-HIGH transition of the SDA line, while SCL is HIGH, is defined as the stop condition. The bus transceiver will be reset on the reception of a start condition. The bus is considered to be busy after the start condition. The bus is considered to be free again after a stop condition. Data format transmitter mode For the data transmission no subaddress is to be transmitted, because there is only one read register implemented. So the total number of bytes reduces from three to two. The second byte represents the status of the IC. Status register (see Table 4) The bit D7 (PONRES) represents the status of the IC and indicates whether the power-on reset was activated by switching-on the supply voltage or a supply voltage breakdown. If so, the I2C-bus transceiver, the digital PLLs and integrators are initialized and the PONRES bit is set to 1998 Jul 03 14
TDA9840
HIGH. After a successful reading of the status register, the bit D7 will be reset to LOW. The bits D5 and D6 represent the transmitter status detected by the identification circuit (stereo, dual or mono transmission). The other bits are set to 0 (default). Data format for the receiver Table 1 Registers for receiver mode (see Table 6) REGISTER Switch register Port register Level adjustment register Stereo adjustment register Test register (00)HEX (01)HEX (without function) (02)HEX (03)HEX (04)HEX VALUE
The port register is without function, because this IC has no control ports as TDA8415/6/7. A data byte for the subaddress (01)HEX will not be stored in any register. An acknowledge will be sent to the microcontroller. The first byte of the data transmission is the slave address and the second byte is the subaddress indicating the data register in which the data shall be stored. Starting from subaddress (00)HEX the n-th data byte will automatically be stored under subaddress n - 1. All 8 bits of the subaddress are decoded by the device. The subaddresses from (04)HEX to (FF)HEX are forbidden for the user. If the I2C-bus transceiver receives subaddresses from (05)HEX to (FF)HEX, no acknowledge will be sent back to the microcontroller. Switch register The source selector is controlled by the switch register. Table 7 shows the modes of operation. Note, that in the event of the external operation mode, no further selection is possible.

Level adjustment register The information about the level adjustment of the AF channel Vi 2 (pin 8) is stored in the level adjustment register (see Table 10). There are 10 steps (positions) of the AF level adjustment stage. The level range is from 2.5 dB up to -2.0 dB in 0.5 dB steps. After a power-on reset, the data byte of the level adjustment register will be set to (00)HEX: 0 dB gain at the AF input Vi 2. Stereo adjustment register The information about the stereo adjustment of the AF channel Vi 1 (pin 7) is stored in the stereo adjustment register (see Table 11). There are 50 steps (positions) of the AF stereo adjustment stage. The stereo range is from 2.5 dB up to -2.4 dB in 0.1 dB steps. After a power-on reset, the data byte of the stereo adjustment register will be set to (00)HEX: 0 dB gain at the AF input Vi 1. Test register (also used for fast mode) Table 12 shows the meaning of the test register. The integration time of the integrator is approximately 1 s (normal mode, default). If the data byte of this register is set to HIGH, the integration time is reduced from approximately 1 to approximately 0.5 s (fast mode, test mode). The pull-in ranges of the identification PLLs are changed to: Stereo: -0.89/+1.15 Hz Dual: 2.05 Hz. If the integration time of the integrator is switched from one mode to the other (i.e. from fast mode/test mode to normal mode), the status register bits D5 and D6 might set to zero internally (MONO). Therefore, the previous status register information has to be stored by the microcontroller until the transmitter status is detected again by the identification circuit (now in the new mode) the first time. The data byte of the test register can be reset in two different ways to (00)HEX: integration time approximately 1 s, normal mode: * after a power-on reset, for instance by switching the power supply Vp off and on again * data transmission via I2C-bus for the test register (see Table 12). Level and stereo adjustment
TDA9840
For the level and stereo adjustment of both AF channels Vi 1 and Vi 2, the following procedure will be recommended. Level adjustment of the AF channel V * Feeds AF signal at the input Vi 2 * Sets the data byte of the switch register (dual mode) to (1A)HEX * Measures the signal at the outputs Vo 2 or Vo 4 * Adjusts the output level with the level adjustment register. Stereo adjustment of the AF channel Vi 1 * Feeds AF stereo signals at the inputs Vi 1 ((L+R)/2) and Vi 2 (R) * Sets the data byte of the switch register (stereo mode) to (2A)HEX * Measures the crosstalk attenuation between Vo 1 and Vo 2 or Vo 3 and Vo 4 * Adjusts the crosstalk attenuation with the stereo adjustment register. During the stereo adjustment the data byte of the level adjustment register does not change. After the level and stereo adjustment, the bytes of the level and stereo adjustment register must be stored by the microcontroller in a memory. (To avoid mis-adjustment it would be wise to compare the stored bytes with the proper adjustment bytes). If the PONRES bit of the status register will be set to HIGH (see status register) the data bytes for these both registers must be sent out of the memory to the TDA9840 via I2C-bus. Also the data byte of the switch register (see Table 7) must be changed, because the AF outputs are muted.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. 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" (order code 9398 652 90011). DIP SOLDERING BY DIPPING OR BY WAVE The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. 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. REPAIRING SOLDERED JOINTS Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, 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. SO REFLOW SOLDERING Reflow soldering techniques are suitable for all SO packages. 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.
TDA9840
Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. WAVE SOLDERING Wave soldering techniques can be used for all SO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end. 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. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. 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. REPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) 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 to 5 seconds between 270 and 320 C.
