Self Tuned Radio (STR)
FEATURES * The tuning system has an optimized IC partitioning both from application (omitting interferences) and flexibility (removable front panel option) point of view: the tuning synthesizer is on-chip with the radio * The tuning quality is superior and requires no IF-counter for stop-detection; it is insensitive to ceramic filter tolerances * In combination with the microcontroller, fast, low-power operation of preset mode, manual-search, auto-search and auto-store are possible * The local (internal) controller function facilitates reduced and simplified microcontroller software * The high integration level means fewer external components with regard to the communication between the radio and the microcontroller and a simple and small Printed-Circuit Board (PCB) * The inherent FUZZY LOGIC behaviour of the Self Tuned Radio (STR), which mimics hand tuning and yields a potentially fast yet reliable tuning operation * The level of the incoming signal at which the radio must lock is software programmable * Two programmable ports * FM-on/off port to control the external FM front-end * High selectivity with distributed IF gain * Soft mute * Signal dependent stereo-blend ORDERING INFORMATION TYPE NUMBER TEA5762H PACKAGE NAME QFP44 DESCRIPTION plastic quad flat package; 44 leads (lead length 1.3 mm); body 10 x 10 x 1.75 mm
TEA5762
* High impedance MOSFET input on AM * Wide supply voltage range of 2.5 to 12 V * Low current consumption 18 mA at AM and FM (including tuning synthesizer for AM) * Low noise figure * Low output distortion * Due to the new tuning concept, the tuning is independent of the channel spacing. GENERAL DESCRIPTION The TEA5762 is a 44-pin integrated AM-radio and FM-IF and demodulator part including a novel tuning concept. The radio part is based on the TEA5712. It is designed for the use with an external FM front-end. The new tuning concept combines the advantages of hand tuning with electronic facilities and features. User `intelligence' is incorporated into the tuning algorithm and an improvement of the analog signal processing is used for the AFC function.

Self Tuned Radio (STR)
FUNCTIONAL DESCRIPTION The TEA5762 is an integrated radio circuit with AM-receiver and FM-IF part with demodulator and stereo decoder. The circuit includes digital tuning and control functions. The radio The AM circuit incorporates a double balanced mixer, a one-pin low-voltage oscillator (up to 30 MHz) and is designed for distributed selectivity. The AM input is designed to be connected to the top of a tuned circuit. AGC controls the IF amplification and for large signals it lowers the input impedance of the AM front-end. The first AM selectivity can be an IF-Tank (IFT) as well as an IFT combined with a ceramic filter; the second one is an IFT. For FM operation an external FM front-end is necessary. This is switched on and off by the FM-ON/OFF signal which is generated in the bus system. The AFC circuit in the TEA5762 provides a tuning voltage to drive the VCO of the external FM front-end. The frequency of the external VCO is counted in the Self Tuned Radio (STR) tuning system. The FM-IF circuit is designed for distributed IF ceramic filters. The FM quadratic detector uses a ceramic resonator. The PLL stereo decoder incorporates a signal dependent stereo-blend circuit and a soft-mute circuit. Tuning The tuning-concept of Self Tuned Radio (STR) is based on FUZZY LOGIC: it mimics hand tuning (hand tuning is a combination of coarse and fine tuning to the qualitatively best frequency position). As a consequence the tuning system is very fast. The tuning algorithm, which is controlled by the sequential circuit (see Fig.1), is completely integrated; so there are only a few external components needed. The bus and the microcontroller can be kept very simple. The bus only consists of three wires (BUS-CLOCK, DATA and WRITE-ENABLE). The microcontroller must basically give two instructions: * Preset operation * Search operation. SEARCH OPERATION PRESET OPERATION
TEA5762
In preset mode, the microcontroller has to load information such as frequency band, frequency and mono/stereo. This information has to be sent via the bus to the STR. The internal algorithm controls the tuning sequence as follows: 1. The information is loaded into a shift register, a last-station memory and the counter. 2. The Automatic Frequency Control (AFC) is switched off. 3. The counter starts counting the VCO frequency and the tuning voltage is varied until the desired frequency roughly equals the real frequency. 4. The AFC is then switched on and the counter is switched off. 5. The real frequency is more precisely tuned to the desired frequency. After the AFC has tuned the real frequency to the desired frequency an in-lock signal can be generated. In order to get a reliable in-lock signal, there are two parameters measured: the field strength and the S-curve. The field strength indicates the strength of the station and by looking at the S-curve the system can distinguish false in-locks from real in-locks (false in-locks occur on the wrong slope of the S-curve). In the FM mode the tuning voltage controls the VCO of the external FM front-end and the frequency of the VCO is counted in the TEA5762. In the event of fading or pulling the in-lock signal becomes logic 0 and the synthesizer will be switched-on again and the algorithm will be repeated.
During a search operation, the only action the microcontroller has to take is: sending the desired band plus the direction and the search sensitivity level to the STR. The search operation is performed by the charge pump until an in-lock signal is generated (combination of measuring the field strength and the S-curve). The AFC then fine tunes to the station. The frequency belonging to the found station will be counted by the counter and written into the last-station memory and the shift register of the counter. At this time the frequency is available in the shift register and can be read by the microcontroller. The microcontroller decides whether the frequency is within the desired frequency band. If so, this frequency can be stored under a preset and if not, a new search action should be started.

To ensure that the search function operates correctly under all conditions the following search sequence must be applied: * Store the current frequency in the memory * Issue the search command * Wait for data valid and read the new frequency * If the new frequency is the same as the stored frequency, issue a pre-set step (e.g. 50 kHz) and start the search sequence again.

These three signals, together with the mono/stereo pin (MO/ST; pin 24), communicate with the microcontroller.

The TEA5762 has a 25-bit shift register; see Table 3 for an explanation of the shift register bits. If in search mode no transmitter can be found, all frequency bits of the shift register are set to logic 0. The bus protocol is depicted in Figs 3 and 4.

READING DATA While WRITE-ENABLE is LOW data can be read by the microcontroller. At a rising edge of the BUS-CLOCK, data is shifted out of the register. This data is available from the point where the BUS-CLOCK is HIGH until the next rising edge of the BUS-CLOCK occurs (see Fig.3). To read the entire shift register 24 clock pulses are necessary. WRITING DATA
TEA5762
While WRITE-ENABLE is HIGH the microcontroller can transmit data to the TEA5762 (hard mute is active). At a rising edge of the BUS-CLOCK, the register shifts and accepts one bit into LSB. At clock LOW the microcontroller writes data (see Fig.4). To write the entire shift register 25 clock pulses are necessary.

SOLDERING 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 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. 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. 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. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 C. 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:
TEA5762
* 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; - 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 is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 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 to 5 seconds between 270 and 320 C.

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. These packages are not suitable for wave soldering as a s 3. older 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, TQFP and QFP 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.
