FUNCTIONAL DESCRIPTION Low-noise RF amplifier
The PLL synthesizer can be clocked externally with a 32.768 kHz, a 6.5 MHz or a 13 MHz signal via pin XTAL2. The crystal oscillator generates the reference frequency for: * The reference frequency divider for the synthesizer PLL * The timing for the IF counter * The free-running frequency adjustment of the stereo decoder VCO * The centre frequency adjustment of the IF filters. 7.5 PLL tuning system
The LNA input impedance together with the LC RF input circuit defines an FM band filter. The gain of the LNA is controlled by the RF AGC circuit. 7.2 FM mixer
The FM quadrature mixer converts the FM RF (76 to 108 MHz) to an IF of 225 kHz. 7.3 VCO
The varactor tuned LC VCO provides the Local Oscillator (LO) signal for the FM quadrature mixer. The VCO frequency range is 150 to 217 MHz. 7.4 Crystal oscillator
The crystal oscillator can operate with a 32.768 kHz clock crystal or a 13 MHz crystal. The temperature drift of standard 32.768 kHz clock crystals limits the operational temperature range from -10 to +60 C.
The PLL synthesizer tuning system is suitable to operate with a 32.768 kHz or a 13 MHz reference frequency generated by the crystal oscillator or applied to the IC from an external source. The synthesizer can also be clocked via pin XTAL2 at 6.5 MHz. The PLL tuning system can perform an autonomous search tuning function. 7.6 RF AGC
The RF AGC prevents overloading and limits the amount of intermodulation products created by strong adjacent channels.

TEA5768HL
I2C-BUS AND BUS-CONTROLLED FUNCTIONS I2C-bus specification
Fully integrated IF filter. 7.8 FM demodulator
The FM quadrature demodulator has an integrated resonator to perform the phase shift of the IF signal. 7.9 Level voltage generator and analog-to-digital converter
Information about the I2C-bus can be found in the brochure "The I2C-bus and how to use it" (order number 9398 393 40011). The standard I2C-bus specification is expanded by the following definitions. IC address C0: 1100000. Structure of the I2C-bus logic: slave transceiver. Subaddresses are not used. The maximum LOW-level input and the minimum HIGH-level input are specified to 0.2VCCD and 0.45VCCD respectively. The pin BUSMODE must be connected to ground. Note: The bus operates at a maximum clock frequency of 400 kHz. It is not allowed to connect the IC to a bus operating at a higher clock rate. 8.1.1 DATA TRANSFER
The FM IF analog level voltage is converted to 4 bits digital data and output via the I2C-bus. 7.10 IF counter I2C-bus.
The IF counter outputs a 7-bit count result via the 7.11 Soft mute
The low-pass filtered level voltage drives the soft mute attenuator at low RF input levels. The soft mute function can be switched off via the I2C-bus. 7.12 MPX decoder
The PLL stereo decoder is adjustment-free. The stereo decoder can be switched to mono via the I2C-bus. 7.13 Signal dependent mono to stereo blend
Data sequence: address, byte 1, byte 2, byte 3, byte 4 and byte 5 (the data transfer has to be in this order). The LSB = 0 of the address indicates a WRITE operation to the TEA5768HL. Bit 7 of each byte is considered as the MSB and has to be transferred as the first bit of the byte. The data becomes valid bitwise at the appropriate falling edge of the clock. 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 is not completed, the new bits will be used, but a new tuning cycle will not be started. The IC can be switched into a low current standby mode with the standby bit; the bus is then still active. The standby current can be reduced by deactivating the bus interface (pin BUSENABLE LOW). If the bus interface is deactivated (pin BUSENABLE LOW) without the standby mode being programmed, the IC maintains normal operation, but is isolated from the bus lines.
With a decreasing RF input level the MPX decoder blends from stereo to mono to limit the output noise. The continuous mono to stereo blend can also be programmed via the I2C-bus to an RF level depending switched mono to stereo transition. Stereo Noise Cancelling (SNC) can be switched off via the I2C-bus. 7.14 Signal dependent AF response
The audio bandwidth will be reduced with a decreasing RF input level. The function can be switched off via the I2C-bus. 7.15 Software programmable ports
Two software programmable ports (open-collector) can be addressed via the I2C-bus. The port 1 (pin SWPORT1) function can be changed with write data byte 4 bit 0 (see Table 13). Pin SWPORT1 is then output for the ready flag of read byte 1.

Low-power FM stereo radio for handheld applications
The software programmable output (SWPORT1) can be programmed to operate as a tuning indicator output. As long as the IC has not completed a tuning action, pin SWPORT1 remains LOW. The pin becomes HIGH, when a preset or search tuning is completed or when a band limit is reached. The reference frequency divider of the synthesizer PLL is changed when the MSB in byte 5 is set to logic 1. The tuning system can then be clocked via pin XTAL2 at 6.5 MHz. 8.2 I2C-bus protocol Write mode address (write) A(2) data byte(s) 8.1.2 POWER-ON RESET

At Power-on reset the mute is set, all other bits are set to LOW. To initialize the IC all bytes have to be transferred.

16 SOLDERING 16.1 Introduction to soldering surface mount packages
TEA5768HL
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. * 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. 16.4 Manual soldering
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 can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 16.2 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, convection or convection/infrared 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 220 C for thick/large packages, and below 235 C for small/thin packages. 16.3 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.
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.

16.5 Suitability of surface mount IC packages for wave and reflow soldering methods
TEA5768HL
SOLDERING METHOD PACKAGE WAVE BGA, HBGA, LFBGA, SQFP, TFBGA HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, SMS PLCC(3), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO 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. 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). 3. 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. 4. 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. 5. 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. 17 DATA SHEET STATUS DATA SHEET STATUS(1) Objective data PRODUCT STATUS(2) Development DEFINITIONS This data sheet contains data from the objective specification for product development.
