In this case, pin DAATD must be connected to ground, which reduces the available alignment range (see Fig.7) * Crystal frequency and general purpose DAA Buffer output for weather band flag - 5-bit DAC for adjustment of the crystal oscillator frequency to align the actual IF frequency to the centre frequency of IF selectivity inside the IF DSP. If the IF DSP can be aligned to the actual IF frequency, this DAA output can be used as general purpose DAC. Figure 3 shows the application of the crystal oscillator with frequency pulling. The buffer output (pin WBFLAG) is HIGH for weather band mode. 7.3 VCO The varactor tuned LC oscillator provides the local oscillator signal for both FM and AM mixers. It has a frequency range from 159.9 to 248.2 MHz. 7.4 DAA To reduce the number of manual alignments in production the following I2C-bus controlled Digital Auto Alignment (DAA) functions are included: FM I/Q-mixer The FM quadrature mixer converts FM RF (64 to 108 MHz and 162.4 to 162.55 MHz) to an IF of 10.7 MHz. It provides inherent image rejection and high dynamic range. The image rejection can be switched from `low' injection Local Oscillator (LO) to `high' injection LO via the I2C-bus. The mixer conversion gain can be increased by 6 dB via the I2C-bus. In this case the threshold of the FM keyed AGC has to be lowered by 6 dB to prevent the mixer from being overloaded. 7.2 TEF6721HL Crystal oscillator handbook, halfpage The crystal oscillator provides a 20.5 MHz signal that is used for: CRYSTAL DAA * Reference frequency for frequency synthesizer PLL 59 * Timing signal for the RDS update algorithm. 7.5 58 2.7 pF 57 The fast synthesizer PLL tuning system with local control is used for inaudible AF updating, combining fast PLL jumps with low reference frequency breakthrough. 1 nF 100 k 100 k BB201 CRYSTAL OSCILLATOR PLL 20.5 MHz MDB413 Fig.3 Crystal oscillator with frequency pulling. It is capable of tuning the following FM and AM bands: * US FM and US IBOC DAB from 87.9 to 107.9 MHz * US weather FM from 162.4 to 162.55 MHz * Europe FM from 87.5 to 108 MHz * Japan FM from 76 to 91 MHz * East Europe FM from 64 to 74 MHz * LW from 144 to 288 kHz * MW from 522 to 1710 kHz (US AM band) * SW from 5.73 to 9.99 MHz (including the 31 m, 41 m and 49 m bands). 2003 Oct 21 22 nF 60 10 Philips Semiconductors Preliminary specification Car radio tuner front-end for digital IF 7.7 FM keyed AGC The AM mixer has a high dynamic range and converts AM RF to an IF frequency of 10.7 MHz. The AGC detects at the FM mixer input and the IF AGC amplifier input. The AGC threshold for the FM mixer input is programmable via the I2C-bus. When the threshold is exceeded, the AGC sources a current to an external PIN diode circuit, keeping the RF signal level at the FM mixer input constant. The outputs of the AM and FM mixers can be separated to allow the use of different IF filters for AM and FM modes. Figure 4 shows this optional application. By adding the resistor R1 between pins AMIFIN and IFAGCBIAS the input impedance of the IF AGC amplifier is matched to the AM IF filter output impedance. The keyed function shifts the threshold of the AGC if the in-band signal is small. This reduces desensitization by other strong transmitters. The amount of threshold shift is limited to 10 dB. The keyed function can be activated via the I2C-bus and is controlled by in-band level information delivered from IF DSP via pin KAGC. The input impedance of the AM IF filter is matched to 330 with R2 and R3. 7.9 AM mixer 8.5 V halfpage handbook, R2 L1 22 AM IF filter R3 FM IF filter 22 nF The AGC detection points for AM RF AGC are at the AM mixer input (threshold programmable via the I2C-bus) and the AM and FM IF AGC amplifier input (fixed threshold). L2 22 nF In FM mode the AM AGC can be activated via the I2C-bus to sink a constant current of 1 mA from the PIN diode. 22 nF R1 7.10 12 AM MIXER 10 11 9 FM I/Q-MIXER 7 6 5 4 3 The output (open-collector) sinks a current which in AM mode is proportional to the voltage at pin TRFAMAGC and in FM mode proportional to the RF level detector voltage (pin TFMAGC) inside the FM AGC. MDB414 Fig.4 Separate IF paths for AM and FM mode. 2003 Oct 21 FM/AM RF AGC buffer This output current can be used to reduce the gain of active antennas before start of RF AGC. IF AGC TEF6721HL AM RF AGC The AM wideband AGC in front of the AM mixer is realized first by a cascoded NPN transistor, which controls the transconductance of the RF amplifier JFET with 10 dB of AGC range. Second, an AM PIN diode stage with 30 dB of AGC range is available. The minimum JFET drain source voltage is controlled by a DC feedback loop (pin VAMCASFB) in order to limit the cascode AGC range to 10 dB. If the cascode AGC is not required, a simple RF AGC loop is possible by using only a PIN diode. In some conditions, noise behaviour will increase. In this case pins VAMCAS and VAMCASFB have to be left open-circuit. In FM mode, the cascode switches off the JFET bias current to reduce total power consumption. The AGC can be activated via the I2C-bus to source a fixed current as a local function for search tuning. In AM mode the AGC can be activated to source a constant 10 mA current into the FM PIN diode. 7.8 TEF6721HL 11 Philips Semiconductors Preliminary specification Car radio tuner front-end for digital IF TEF6721HL 8 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

Quality tests in IF DSP should take place during the HIGH phase of AFSAMPLE. t1 is the internal TEF6721HL clock related logic delay: 100 s. t2 should be >1.1 ms to ensure correct loading of PLL for the main channel. t3 should be >0 to ensure inaudible update. t4 = 500 s.

The bus pins tolerate also thresholds of a 5 V bus. * If the transfer of a byte is not completed, this byte is lost and the previous information is available. The standard I2C-bus specification is expanded by the following definitions. 12.1.2 For new frequency setting, in both AM and FM mode, the programmable divider is enabled by setting bit PRESET to logic 1. To select a frequency, two I2C-bus transmissions are necessary: IC addresses: * 1st IC address C2H: 1100001 R/W * 2nd IC address C0H: 1100000 R/W * First: bit PRESET = 1 * 3rd IC address C4H: 1100010 R/W. * Second: bit PRESET = 0. Structure of the I2C-bus logic: slave transceiver with auto increment. 12.2 Subaddresses are not used. 12.2.1 I2C-bus The second address can be selected by connecting pin ADDRSEL via a 120 k resistor to GND. The third I2C-bus address can be selected by connecting pin ADDRSEL via a 33 k resistor to GND. The maximum bit rate for this device is 100 kbits/s. The I2C-bus interface is extended with an enable input (pin BUSENABLE). If pin BUSENABLE is HIGH the communication with the device is active; if pin BUSENABLE is LOW the signals on the I2C-bus are ignored so that higher bit rates (>100 kbits/s) can be used to communicate with other devices on the same I2C-bus. The enable signal must not change while bus communication takes place.

The LSB of the address being logic 0 indicates a write operation. 1. Pin ADDRSEL left open-circuit activates 1st IC address; Rext = 120 k at pin ADDRSEL to ground activates 2nd IC address; Rext = 33 k at pin ADDRSEL to ground activates 3rd IC address. Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of the byte. 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. 2. Read or write bit: 0 = write operation to TEF6721HL 1 = read operation from TEF6721HL. 2003 Oct 21 A(2) Notes No default settings at power-on reset.

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). * 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): 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 TEF6721HL - 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. Reflow soldering The footprint must incorporate solder thieves at the downstream end. 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. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. * 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. 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. 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 reflow peak temperatures range from 215 to 270 C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. * below 220 C (SnPb process) or below 245 C (Pb-free process) A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. - for all BGA and SSOP-T packages 16.4 - for packages with a thickness 2.5 mm 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. - for packages with a thickness < 2.5 mm and a volume 350 mm3 so called thick/large packages. * below 235 C (SnPb process) or below 260 C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 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. 2003 Oct 21 Manual soldering 45 Philips Semiconductors Preliminary specification Car radio tuner front-end for digital IF 16.5 TEF6721HL Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE BGA, LBGA, LFBGA, SQFP, SSOP-T(3), TFBGA, VFBGA not suitable suitable(4) REFLOW(2) suitable DHVQFN, HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS not PLCC(5), SO, SOJ suitable LQFP, QFP, TQFP not recommended(5)(6) suitable SSOP, TSSOP, VSO, VSSOP not recommended(7) suitable PMFP(8) not suitable not suitable suitable suitable Notes 1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. 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". 3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 C 10 C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. 4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. 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. 6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP 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. 8. Hot bar or manual soldering is suitable for PMFP packages. 2003 Oct 21 46 Philips Semiconductors Preliminary specification Car radio tuner front-end for digital IF TEF6721HL 17 DATA SHEET STATUS LEVEL DATA SHEET STATUS(1) PRODUCT STATUS(2)(3) Development DEFINITION I Objective data II Preliminary data Qualification This data sheet contains data from the preliminary specification.
