7 7.1 7.1.1 FUNCTIONAL DESCRIPTION Oscillators VCO 7.3 7.3.1 FM signal channel FM MIXER 1
TEA6849H
The varactor tuned VCO provides the local oscillator signal for both FM and AM mixer 1. It has a frequency range of 162.9 to 248.2 MHz. 7.1.2 PLL
FM quadrature mixer converts FM RF (65 to 108 MHz and weather band) to IF of 10.7 MHz. The FM mixer provides inherent image rejection and high RF sensitivity. It is capable of tuning the US FM, US weather, Europe FM, Japan FM and East Europe FM bands: · US FM = 87.9 to 107.9 MHz · US weather FM = 162.4 to 162.55 MHz · Europe FM = 87.5 to 108 MHz · Japan FM = 76 to 91 MHz · East Europe FM = 65 to 74 MHz. 7.3.2 BUFFER OUTPUT FOR WEATHER BAND FLAG (PIN WBFLAG)
Fast synthesizer PLL tuning system with local control for inaudible RDS updating. 7.1.3 CRYSTAL OSCILLATOR
The crystal oscillator provides a 20.5 MHz signal that is used for: · Reference frequency for frequency synthesizer PLL · Local oscillator for AM mixer 2 and FM mixer 2 · Reference frequency for the IF counter · Timing signal for the RDS update algorithm · Reference frequency (75.368 kHz) for the TEA688x (car audio signal processor - CASP) or TEF689x (car radio integrated signal processor - CRISP). 7.2 DAA
The buffer output on pin WBFLAG is HIGH for weather band mode. 7.3.3 FM KEYED AGC
To reduce the number of manual alignments in production the following I2C-bus controlled Digital Auto Alignment (DAA) functions are included: · 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 · IF2 centre DAA Centre frequency alignment (7-bit) of integrated FM IF2 dynamic selectivity.
The AGC threshold is programmable and the keyed AGC function is switchable via the I2C-bus. AGC detection occurs at the input of the first 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. 7.3.4 FM IF AMPLIFIER
The FM IF amplifier provides 18 dB amplification with high linearity over a wide dynamic range. 7.3.5 FM MIXER 2
The FM mixer 2 converts 10.7 MHz FM IF1 to 450 kHz FM IF2 in I and Q phase to achieve image rejection in the demodulator.

7.3.6 FM IF2 DYNAMIC SELECTIVITY 7.4.2 AM RF AGC
TEA6849H
The IF bandwidth of the FM IF2 is automatically adjusted depending on modulation and reception conditions. The centre frequency of the selectivity is adjusted by a 7-bit instruction via the I2C-bus. The dynamic selectivity mode and three fixed bandwidths (60, 90 and 130 kHz) can be selected via the I2C-bus. The IF2 bandwidth is set to 13 kHz in weather band mode. 7.3.7 FM QUADRATURE DEMODULATOR
The FM quadrature demodulator is adjustment free. 7.3.8 FM MPX SOFT MUTE
Muting depth and start of muting are adjustable via the I2C-bus (see Figs 8 and 9). 7.3.9 ADJACENT CHANNEL DETECTOR AND THRESHOLD
EXTENSION
The AM wideband AGC in front of the first AM mixer is realized first by a cascaded NPN transistor, which controls the transconductance of the RF amplifier JFET with 10 dB of AGC range. Second, an AM PIN diode stage with antenna type and frequency dependent 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 this event pins VAMCASFB and VAMCAS have to be open-circuit. In FM mode, the cascade switches off the JFET bias current to reduce total power consumption. The PIN diode is biased by 1 mA in FM mode. The AGC detection points for AM AGC are at the first AM mixer input (threshold programmable via the I2C-bus) and the IF2 AGC input (fixed threshold). 7.4.3 AM DETECTOR
In the event of breakthrough of a strong neighbouring transmitter, the IF2 bandwidth is reduced dynamically. At low RF input voltages and low modulation levels the IF2 bandwidth is reduced to achieve improved sensitivity by demodulator threshold extension. 7.3.10 BANDWIDTH CONTROL `ACTIVE' FLAG (PIN IFBWFLAG)
The AM output provides either a detected AM AF or the corresponding AM IF2 signal. The IF2 signal can be used for AM stereo decoder processing. Soft mute function is controlled by the I2C-bus in AM mono mode. 7.4.4 AM NOISE BLANKER
Flag output IBFW = 1 from pin IFBWFLAG indicates that the IF2 bandwidth is reduced. 7.3.11 BANDWIDTH CONTROL MONITOR VOLTAGE (PIN VIFBW)
The detection point for the AM noise blanker is the output stage of AM mixer 1, while blanking is realized at the output of the mixer 2. Trigger sensitivity can be modified by adding an external resistor at pin AMNBHOLD. 7.5 FM and AM level detector
The actual bandwidth is indicated by a voltage at pin VIFBW that is proportional, not linear, to the IF bandwidth. 7.4 7.4.1 AM signal channel AM TUNER INCLUDING MIXER 1 AND MIXER 2
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.
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 IF1 of 10.7 MHz, while AM mixer 2 converts IF1 of 10.7 MHz to IF2 of 450 kHz: · LW = 144 to 288 kHz · MW = 530 to 1710 kHz (US AM band) · SW = 5.73 to 9.99 MHz (including the 31 m, 41 m and 49 m bands).

12 I2C-BUS PROTOCOL 12.1 I2C-bus specification 12.1.2 I2C-BUS PULL-UP RESISTORS
TEA6849H
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 addresses: · 1st IC address C2H: 1100001 R/W · 2nd IC address C0H: 1100000 R/W. Structure of the increment. I2C-bus logic: slave transceiver with auto
When the IC is used together with the TEA688x or TEF689x and both SCL and SDA lines are connected via the I2C-bus to the TEA688x or TEF689x, the pull-up resistors of the tuner IC should be connected to the digital supply voltage of the TEA688x or TEF689x. Otherwise an I2C-bus pull-down can occur switching off the tuner IC supply when the I2C-bus buffer interface of the TEA688x or TEF689x is enabled for data transfer to the tuner IC. 12.1.3 FREQUENCY SETTING
Subaddresses are not used. A second I2C-bus address can be selected by connecting pin FREF via a 68 k resistor to GND. Exception to the standard I2C-bus specification: · The data hold time tHD;DAT must be at least 1 µs. 12.1.1 DATA TRANSFER
For new frequency setting, in both AM and FM mode, the programmable divider is enabled by setting bit MUTE = 1. To select an FM frequency, two I2C-bus transmissions are necessary: · First: bit MUTE = 1 · Second: bit MUTE = 0. 12.1.4 DEFAULT SETTINGS
No default settings at power-on reset. One I2C-bus transmission is required to program the IC.
Data sequence: address, byte 0, byte 1, byte 2, byte 3, byte 4, byte 5, byte 6, and byte 7. The data transfer has to be in this order. The LSB = 0 indicates a WRITE operation to the TEA6849H. 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. 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, this byte is lost and the previous information is available.

Table 26 Description of data byte 7 bits BIT 7 6 5 to 3 2 to 0 SYMBOL - FMSM SSL[2:0] SST[2:0] DESCRIPTION This bit is not used and must be set to logic 0. FM soft mute. If FMSM = 0, then FM soft mute is off. If FMSM = 1, then FM soft mute is on. Setting of FM soft mute slope; 000 is flattest setting; see Fig.8 Setting of soft mute start; 000 is lowest setting; see Fig.9
