The FM mixer provides inherent image rejection and high RF sensitivity. The image rejection can be switched from ‘low’ injection Local Oscillator (LO) to ‘high’ injection LO via the I2C-bus. The mixer 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. • FM RF DAA – 7-bit DAA circuitry for the conversion of the VCO tuning voltage to a controlled alignment voltage for the FM antenna tank circuit • FM and AM level DAA – Level DAA circuitry for alignment of slope (3-bit) and starting point (5-bit) of the level curve. The mixer is capable of tuning the: • US FM and US IBOC DAB from 87.9 to 107.9 MHz 7.7 • US weather FM from 162.4 to 162.55 MHz The AGC threshold is programmable and the keyed AGC function is switchable via the I2C-bus. AGC detection occurs at the input of the FM mixer. If the keyed AGC function is activated, the AGC is keyed only by the narrow-band level. The AGC PIN diode drive can be activated via the I2C-bus as a local function for search tuning. The AGC sources a constant 10 mA current into the FM PIN diode in AM mode. • Europe FM from 87.5 to 108 MHz • Japan FM from 76 to 91 MHz • East Europe FM from 64 to 74 MHz. 7.2 Buffer output for weather band flag The buffer output (pin WBFLAG) is HIGH for weather band mode. 7.3 7.8 VCO Crystal oscillator 7.9 The crystal oscillator provides a 20.5 MHz signal that is used for: • Local oscillator for AM mixer 2 • Reference frequency for the IF counter • Timing signal for the RDS update algorithm. PLL The fast synthesizer PLL tuning system with local control is used for inaudible RDS updating. 2003 Oct 21 FM IF AGC This is a linear FM IF AGC amplifier with multiplexed inputs for FM standard and FM IBOC DAB. The gain controlled FM IF is output by the multiplexed FM IF/AM IF2 buffer for a car IF DSP IC (e.g. SAA7724H). • Reference frequency for frequency synthesizer PLL 7.5 FM IF amplifier The FM IF amplifier provides 10.5 or 14 dB gain, selectable via the I2C-bus with high linearity over a wide dynamic range. In IBOC DAB mode (activated via I2C-bus) FM IF is buffered and directly fed to FM IF AGC bypassing the second FM ceramic filter. The varactor tuned LC oscillator provides the local oscillator signal for both FM and AM mixer 1. It has a frequency range from 159.9 to 248.2 MHz. 7.4 FM keyed AGC 10 Philips Semiconductors Product specification Car radio tuner front-end for digital IF 7.10 TEF6700HL 7.12 AM tuner including mixer 1 and mixer 2 The detection point for the AM noise blanker is the output stage of AM mixer 1, while blanking is realized at the output of mixer 2. The AM tuner is realized in a double conversion technique and is capable of selecting LW, MW and SW bands. AM mixer 1 converts AM RF to an IF1 of 10.7 MHz, while AM mixer 2 converts IF1 of 10.7 MHz to IF2 of 450 kHz: 7.13 • LW from 144 to 288 kHz • SW from 5.73 to 9.99 MHz (including the 31 m, 41 m and 49 m bands). 7.14 AM RF AGC FM IF and AM IF2 buffer This buffers and multiplexes AM IF2 and FM IF to pin IFOUT. The AM wideband AGC in front of the AM mixer 1 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 PIN diode is biased by 1 mA in FM mode. 7.15 FM and AM level detector The FM and AM level detectors provide the temperature compensated output voltage. The starting points and slopes of the level detector outputs are programmable via the I2C-bus. 7.16 FM/AM RF AGC buffer 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. The AGC detection points for AM RF AGC are at the AM mixer 1 input (threshold programmable via the I2C-bus) and the IF2 AGC input (fixed threshold). 2003 Oct 21 AM IF2 AGC This is a linear AM IF2 AGC amplifier. The gain controlled AM IF2 is output via the multiplexed FM IF/AM IF2 buffer to a car IF DSP IC (e.g. SAA7724H). • MW from 522 to 1710 kHz (US AM band) 7.11 AM noise blanker 11 Philips Semiconductors Product specification Car radio tuner front-end for digital IF TEF6700HL 8 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

PLL registers are loaded during load PLL = 1, but actual frequency jumps take place at the falling edge of this signal. IF counting is carried out during AFSAMPLE = 1. 10 µs after falling edge of AFSAMPLE result is valid for AF and remains valid until read by microcontroller. Quality tests in a car IF DSP IC (e.g. SAA7724H) should take place 2 ms after falling edge of AFHOLD. t1 is the internal TEF6700HL clock related logic delay: 100 µs. 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 µs.

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 kΩ resistor to GND. The third I2C-bus address can be selected by connecting pin ADDRSEL via a 33 kΩ 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.

MODE(2) IC ADDRESS(1) ADDRESS No default settings at power-on reset. I2C-bus transmission is required to program the IC. 1 1 1 0 0 0 0 1 R/W 2 1 1 0 0 0 0 0 R/W 3 1 1 0 0 0 1 0 R/W Notes 1. Pin ADDRSEL left open-circuit activates 1st IC address; Rext = 120 kΩ at pin ADDRSEL to ground activates 2nd IC address; Rext = 33 kΩ at pin ADDRSEL to ground activates 3rd IC address. The data transfer has to be in this order. The LSB of the address being logic 0 indicates a write operation. Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of the byte. 2. Read or write bit: 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. 2003 Oct 21 I2C-bus protocol Notes The data hold time tHD;DAT must be at least 1 µs. 12.1.1 FREQUENCY SETTING 0 = write operation to TEF6700HL 1 = read operation from TEF6700HL. 31 Philips Semiconductors Product specification Car radio tuner front-end for digital IF 12.2.2 TEF6700HL WRITE MODE: DATA BYTE 0 Table 4 Format of data byte 0 BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0 AF PLL14 PLL13 PLL12 PLL11 PLL10 PLL9 PLL8 Table 5 Description of data byte 0 bits BIT SYMBOL DESCRIPTION 7 AF Alternative frequency.

REFERENCES OUTLINE VERSION IEC JEDEC SOT314-2 136E10 MS-026 2003 Oct 21 JEITA EUROPEAN PROJECTION ISSUE DATE 00-01-19 03-02-25 51 Philips Semiconductors Product specification Car radio tuner front-end for digital IF To overcome these problems the double-wave soldering method was specifically developed. 16 SOLDERING 16.1 Introduction to soldering surface mount packages If wave soldering is used the following conditions must be observed for optimal results: 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). • 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 TEF6700HL – 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 52 Philips Semiconductors Product specification Car radio tuner front-end for digital IF 16.5 TEF6700HL 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 53 Philips Semiconductors Product specification Car radio tuner front-end for digital IF TEF6700HL 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.
