FUNCTIONAL DESCRIPTION Stereo decoder By changing the value of the input resistor at pin 12 the MPX input can be adapted to the level of the FM demodulator output (see Fig.16). 1998 Mar 24 6
A 3rd order low-pass filter (fg = 90 kHz) at the MPX input provides an extra 190 kHz ACI suppression. An interference gate is connected at the MPX demodulator outputs. For AM the VCO is switched off.

Notes to the characteristics 1. For typical adjusting range see Figs 10 and 13. 2. For typical curve see Fig.11. 3. The static mute voltage follows the unweighted voltage level as function of FM-IF2 voltage and level adjustment voltage V38-4. It additionally depends on multi-path level, noise (adjacent channel interferences) and the position of TSWITCH (pin 3). For typical curve for mute voltage dependence see Fig.12. 4. The mono/stereo blend voltage is generated as a function of FM-IF2 voltage, multi-path level, noise and position of TSWITCH. 5. The high-cut control voltage is generated as a function of FM-IF2 voltage, multi-path level, noise and position of TSWITCH. 6. fIF1 = 10.7 MHz; fIF2 = 450 kHz for AM mixer. 7. The AM oscillator signal is generated by division of the 61.5 MHz crystal oscillator. Two divider ratios programmable by the I2C-bus: divide by 6 (AM-IF1 = 10.7 MHz); divide by 2 (AM-IF1 = 30 MHz). 8. For typical AM level curve see Fig.15. 9. For AM detector; fAMIF2 = 450 kHz; fmod = 400 Hz; m = 30%.

I2C-BUS AND I2C-BUS CONTROLLED FUNCTIONS I2C-bus specification The standard I2C-bus specification is expanded by the following definitions. Structure of the I2C-bus logic: slave transceiver with auto increment and expansion to switch a direct transfer of all transmissions to an output for the radio front-end IC (TEA6810T respectively TEA6811T). Subaddresses are not used. DATA TRANSFER FOR THE TEA6823T AND THE TEA6825T Data sequence: * Address * Byte 1 * Byte 2. The data transfer may be in this order only. The transfer direction of the data bytes is defined by the LSB of the address. The data becomes valid at the output of the internal latches with the acknowledge of each byte. A STOP condition after any byte can shorten transmission times. When writing to the transceiver by using the STOP condition before completion of the whole transfer: * The remaining bytes will contain the old information * If the transfer of a byte was not completed, this byte is lost and the previous information is available. DATA TRANSFER TO AN OUTPUT OF THE FRONT-END IC A data bit in the transceiver of the TEA6823T or TEA6825T enables or disables a direct transfer of all transmissions to an interface stage for the front-end IC. For a transmission to the front-end IC the address and the data format of the front-end IC has to be used. Remark: the pull-up resistors for the front-end interface (pins 6 and 7) should not be connected to the 5 V supply voltage of the front-end IC, otherwise a bus pull-down (pin 53) can occur during switching off the front-end supply when the interface stage is enabled. DATA TRANSFER TO THE IF IC Data transfer to the IF IC (TEA6823T or TEA6825T) is independent of the state of interface stage for the front-end IC. BIT 3 0 0 0 0 1 1 1 1 7 Table 1

IF-counter read out as a function of FM or AM position, counter window and prescaler setting FM/AM FM FM FM FM(1) AM AM(1) Note 1. In position FM with a prescaler ratio of 25, counter window of 40 ms and in position AM with 40 ms counter window ambiguous counting results within the IF filter bandwidth are obtained. The counting range is 127 counts above and 127 counts below the nominal IF of 10.7 MHz for FM and 450 kHz for AM. The IF-count windows are valid for a crystal oscillator frequency of 61.5 MHz. The FM/AM switching is carried out by bit 0 of byte 2 of the received data of the IC. The IF-counter operates continuously. The IF-counter and window-counter will be reset when the I2C-bus logic detects the address of the IC. This disables changes in the latches for the IF-count, while reading this value. If the transmission to the front-end IC is disabled after the synthesizer loop of the TEA6810T/TEA6811T front-end IC has locked for a new frequency, the IF-count will be available after the set measuring time. The IF-counter starts at 0. The IF-counter output are the 8 least significant bits of the counting result.

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). Reflow soldering Reflow soldering techniques are suitable for all VSO 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. 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
TEA6823T; TEA6825T
Wave soldering techniques can be used for all VSO 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.

This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale PURCHASE OF PHILIPS I2C COMPONENTS
Purchase of Philips I2C components conveys a license under the Philips' I2C patent to use the components in the I2C system provided the system conforms to the I2C specification defined by Philips. This specification can be ordered using the code 9398 393 40011.
