circuit description 3.4.1 mixer-oscillator-block, saw filter driver the mixer-oscillator block includes three balanced mixers (one mixer with an unbalanced high-impedance input and two mixers with a balanced low-impedance input), two 2-pin asymmetrical oscillators for the low and the mid band, one 4-pin symmetrical oscillator for the high band, a reference voltage, and a band switch. filters between tuner input and ic separate the tv frequency signals into three bands. the band switching in the tuner front-end is done by using three pnp port outputs. in the selected band, the signal passes through a tuner input stage with a mosfet amplifier, a double-tuned bandpass filter and is finally fed to the mixer input of the ic. the impedance of the mixer at low band has high ohmic, while mid or high band has a low ohmic input. the input signal is mixed there with the signal from the activated on chip oscillator to the if frequency. the if is filtered by means of an external saw filter (surface acoustic waves filter) in between the 2 mixer output pins and the 2 input pins of the following saw filter driver. the saw filter driver has a low output impedance to drive the saw filter directly. 3.4.2 rf agc the rf agc stage combines a wide band and a narrow band detection. the wide band detector (wb) detects the input signal directly at the rf input for each band. the narrow band detector (nb) detects the level of the saw filter driver output signal. if both detected levels are below the rf agc take-over points, a external capacity will be charged with the source current of 300 na or 9 a (release current). if one of the detected levels is above the rf agc take-over points, the external capacity will be discharged with the sink current of 100 a (attack current). the integrated current generates an agc voltage for gain control of the tuners input transistors. the agc take- over and the time constant are selectable by the i 2 c bus as shown in table 17 "subaddress 03h, agc control and if signal processing control" on page 52 . an integrated rf agc buffer allows to monitor the agc voltage without any influence on the tuner gain control. this buffer can be disabled as shown in table 16 "subaddress 02h, reference divider r and crystal oscillator control" on page 50 3.4.3 if agc amplifier coming out of the saw filter the if signal is sent through a vga (variable gain amplifier) which will set the differential if output signal to the desired level (preferably 1 vpp). the gain of the vga is determined by the dc-voltage at pin ifampagc data sheet 23 revision 3.1, 2006-12-19 tua 6045-2 taifun 3 functional description 3.4.4 pll block, xtal oscillator the vco frequency f osc is stabilized by a digital cmos pll (phase locked loop, frequency synthesizer). the oscillator signal is internally dc-coupled as a differential signal to the programmable divider input. the signal subsequently passes through a programmable divider (n) and then the divided vco signal: is compared in a digital frequency/phase detector (pd, frequency detector) with a programmable reference frequency: which is derived from a quartz reference f xtal divided by a programmable reference divider (r). the phase detector has a linear operating range without a dead zone for very small phase deviations. a programmable abl pulse width (anti backlash) works against the delay of the charge pump cell. the selectable abl pulse width values have been implemented for test purpose only and have no performance effects. the phase detector has two outputs (up & down) that drive two current sources of opposite polarity as charge pump (cp). if the negative edge of the divided vco signal appears prior to the negative edge of the reference signal, the positive current source (i source ) pulses for the duration of the phase difference. in the reverse case the negative current source (i sink ) pulses. if the two signals are in phase (pll is locked), the integrated charge pump current is approximately zero. in case of active closed loop control the charge pump provides programmable output current drive capability to optimize the loop requirements. the charge pump currents are programmable from 0 to 1.125 ma in steps of 75 a. the pll contains an integrated lock detector. a lock-in flag is set when the loop is locked. it can be read by the processor via the common i 2 c/3-wire bus. the crystal oscillator (xtal) is an unbalanced pierce oscillator which operates in parallel resonance with quartz crystals from 4...16 mhz. by programming it?s possible to pass the oscillator frequency f xtal through a divider stage to a buffered output pin or to use an external quartz clock for the reference oscillator via a switchable preamplifier for test purpose only. 3.4.5 bus interface the programming of the cmos frequency synthesizer is done via a combined serial i 2 c/3-wire bus interface. the choice of the desired bus is made by a bus mode select signal at pin busmode. f div f osc n ----------- - n240 65535 = () , = f ref f xtal r --------------- r2 1023 = () , = data sheet 24 revision 3.1, 2006-12-19 tua 6045-2 taifun 3 functional description in i 2 c-bus mode four different chip addresses can be set by appropriate dc levels at pin cas (chip address select), while in 3-wire mode the chip is addressed by a low active enable signal at pin en. the content of the bus telegram (serial data format) is controlled by software programming and assigned to the registers of the functional units according to the several sub addresses. the most significant bit (msb) of the data protocol is shifted in first. the clock is generated by the processor (input pin scl/clock), while pin sda/data functions as an input or an output (open drain, external pull-up resistor) depending on the direction of the data (write or read mode). both inputs have schmitt-trigger circuits with hysteresis and furthermore a low-pass characteristic, which suppress a certain noise level on the bus lines and enhance so the noise immunity of the combi-bus. a detailed description of the chip address organization in i 2 c-mode as well as the used sub addresses of the data registers is given in chapter 5.2 "bus interface" on page 41 - and the programmable i 2 c/3-wire bus data format is shown in chapter 5.3 "bus data format" on page 43 . 3.4.6 dc/dc clock output to drive a bipolar npn switching transistor of an external dc/dc converter directly, a programmable dc/dc clock generator is integrated. the clock frequency and the duty cycle of the dc/dc clock generator can be set over the i 2 c/3-wire bus as shown in table 18 "subaddress 04h, dc-dc converter" on page 54 . 3.4.7 power-on reset, stand-by condition while applying the supply voltage, integrated power-on reset circuits ensure a defined state after initial power-up. the required programming data will be set to default values. when v cc fall below approximately 1.2 v (typ.) the power-on resets go active and tie all write data registers to their power-on defaults (= power-down reset). while power-on reset is active no programming is possible. the power-on flags (pofx) are set at power-on and when v vccx falls below appr. 1.2 v (typ.). they will be reset at the end of a read operation of the status register. by programmable stand-by control bits it?s possible to reduce the current consumption of the ic up to 99%. in the full stand-by mode only bus interface is staying active and the current consumption is reduced below 200 a. after power-on reset only bus interface and xtal-oscillator with bandgap are active and the current consumption is about 2.6 ma (typ.). data sheet 25 revision 3.1, 2006-12-19 tua 6045-2 taifun 3 functional description 3.4.8 if switch, loop thru for the alignment procedure of the tuner module two programmable switches are integrated to bypass the bandpass, the saw driver and the saw filter. the first switch called ?if switch? can switch between the mixer output signal and the bandpass output signal. the second switch called ?loop thru? can switch between the signal after the first stage of the if agc amplifier and the saw filter output signal. figure 3 functional block diagram of if switch and loop thru band- pass mixer if switch sawdrv mixer input if output saw filter if agc amplifier loop thru if switch control = bit 15 of

reference 5.2 bus interface table 7 pin function 1) values are referred to figure 4.2 "application circuit for hybrid application" on page 27 and f if =36mhz, unless stated otherwise. 2) the rf frequency range is defined by the oscillator frequency range and the intermediate frequency (if). 3) local oscillator fm modulation resulting from i 2 c communication is measured at the if output using a modulation analyzer with a peak to peak detector ((p + + p - ) / 2) and a post detection filter 20 hz - 100 khz. the i 2 c messages are sent to the tuner in such a way that the tuner is addressed but the content of the pll registers are not altered. the refresh interval between each data set shall be 20 ms to 1 s. 4) (n+5) -1 mhz is defined as the input level of channel n+5, at frequency 1 mhz lower, causing 100 khz fm sidebands 30 db below the wanted carrier. 5) impedance measured with differential 2-port measurement at input or output. input and output pins directly connected to measurement equipment with 50 ? strip lines. 6) limits are related to the tank circuit used in the application board. frequency bands may be adjusted by the choice of external components. 7) the supply ripple susceptibility is a sideband measurement using a spectrum analyzer connected to the if output. an unmodulated rf signal with a level of 80 dbv is applied to the test board rf input. a sinewave signal with a defined frequency is superposed onto the supply voltage (see figure 16 "ripple susceptibility measurement" on page 62 ). the specified value is the worst case in the frequency range. 8) this is the level of divider interferences close to the if frequency. for example channel s3: f osc = 158.15 mhz, 1/4 f osc = 39.5375 mhz. the rejection has to be greater than 60 db for an saw driver output of 100 dbv. 9) crystal oscillator interference means the 4 mhz sidebands caused by the crystal oscillator. the rejection has to be greater than 60 db for an saw driver output of 100 dbv. 10) the reference frequency rejection is the level of reference frequency sidebands (e.g. 62.5 khz) related to the carrier. the rejection has to be greater than 60 db for an saw driver output of 100dbv. 11) channel s02 beat is the interfering product of f rfpix , f if and f osc of channel s02, f beat = 37.35 mhz. the possible mechanisms are f osc - 2 x f if or 2 x f rfpix - f
