Product Description
2.1 Overview
The TUA6030, TUA6032 devices combine a mixer-oscillator block with a digitally programmable phase locked loop (PLL) for use in TV and VCR tuners.
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, an IF amplifier, a reference
voltage, and a band switch.
The PLL block with four independently selectable chip addresses forms a digitally programmable phase locked loop. With a 4 MHz quartz crystal, the PLL permits precise setting of the frequency of the tuner oscillator up to 1024 MHz in
increments of 31.25, 50, 62.5 or 166.7 kHz. The tuning process is controlled by
a microprocessor via an I2C bus. The device has 8 output ports, one of them
(P6) can also be used as ADC input port. A flag is set when the loop is locked.
The lock flag can be read by the processor via the I2C bus.

3.4 Circuit Description
3.4.1
Mixer-Oscillator block
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, an IF amplifier, 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 a tuner input stage with a
MOSFET amplifier, a double-tuned bandpass filter and is then fed to the mixer
input of the IC which has in case of LOW band a high-impedance input and in
case of MID or HIGH band a low-impedance input. The input signal is mixed
there with the signal from the activated on chip oscillator to the IF frequency
which is filtered out at the balanced mixer output pair by means of a parallel
tuned circuit. The following IF amplifier is capacitively coupled to the mixer outputs and has a low output impedance to drive the SAW filter directly.
3.4.2
PLL block
The oscillator signal is internally DC-coupled as a differential signal to the programmable divider inputs. The signal subsequently passes through a programmable divider with ratio N = 256 through 32767 and is then compared in a digital
frequency/phase detector with a reference frequency fref = 31.25, 50, 62.5 or
166.7 kHz. This frequency is derived from an unbalanced, low-impedance 4
MHz crystal oscillator (pin XTAL) divided by 128, 80,64 or 24. The reference frequencies will be different with a quartz other than 4 MHz.
The phase detector has two outputs which drive two current sources of a charge
pump. If the negative edge of the divided VCO signal appears prior to the negative edge of the reference signal, the positive current source pulses for the
duration of the phase difference. In the reverse case the negative current
source pulses. If the two signals are in phase, the charge pump output (CP)
goes into the high-impedance state (PLL is locked). An active low-pass filter
integrates the current pulses to generate the tuning voltage for the VCO (internal amplifier, external pull-up resistor at VT and external RC circuitry). The
charge pump output is also switched into the high-impedance state if the control
bits T2, T1,T0 = 0, 1, 0. Here it should be noted, however, that the tuning voltage can alter over a long period in the high impedance state as a result of self
discharge in the peripheral circuity. VT may be switched off by the control bit OS
to allow external adjustments.
If the VCO is not oscillating the PLL locks to a tuning voltage of 33V (VTH).
Wireless Components

Specification, July 2001
TUA6030, TUA6032
Functional Description
By means of control bit CP the pump current can be switched between two values by software. This programmability permits alteration of the control response
of the PLL in the locked-in state. In this way different VCO gains can be compensated, for example.
The software controlled ports P0 to P7 are general purpose open-collector outputs. The test bits T2, T1, T0 =1, 0, 0 switch the test signals fdiv (divided input
signal) and fref (i.e.4 MHz / 64) to P4 and P5 respectively.
The lock detector resets the lock flag FL if the width of the charge pump current
pulses is greater than the period of the crystal oscillator (i.e. 250 ns). Hence, if
FL = 1, the maximum deviation of the input frequency from the programmed frequency is given by
∆f = ± IP ∗ (KVCO / fXTAL) ∗ (C1+C2) / (C1∗C2)
where IP is the charge pump current, KVCO the VCO gain, fXtal the crystal oscillator frequency and C1, C 2 the capacitances in the loop filter (Chapter 4). As the
charge pump pulses at i.e. 62.5 kHz (= fref), it takes a maximum of 16 µs for FL
to be reset after the loop has lost lock state.
Once FL has been reset, it is set only if the charge pump pulse width is less than
250 ns for eight consecutive fref periods. Therefore it takes between 128 and
144 µs for FL to be set after the loop regains lock.
3.4.3
AGC
The wide-band AGC stage detects the level of the IF output signal and generates an AGC voltage for gain control of the tuner input transistors. The AGC
take-over and the time constant are selectable by the I2C bus.
3.4.4
I2C-Bus Interface
Data is exchanged between the processor and the PLL via the I2C bus. The
clock is generated by the processor (input SCL). Pin SDA functions as an input
or output depending on the direction of the data (open collector, external pullup resistor). Both inputs have a hysteresis and a low-pass characteristic, which
enhance the noise immunity of the I2C bus.
The data from the processor pass through an I2C bus controller. Depending on
their function the data are subsequently stored in registers. If the bus is free,
both lines will be in the marking state (SDA, SCL are high). Each telegram
begins with the start condition and ends with the stop condition. Start condition:
SDA goes low, while SCL remains high. Stop condition: SDA goes high while
Wireless Components
3 - 21
Specification, July 2001
TUA6030, TUA6032
Functional Description
SCL remains high. All further information transfer takes place during SCL = low,
and the data is forwarded to the control logic on the positive clock edge.
The table ’Bit Allocation’ (see Table 5-4 Bit Allocation Read / Write on page 39)
should be referred to for the following description. All telegrams are transmitted
byte-by-byte, followed by a ninth clock pulse, during which the control logic
returns the SDA line to low (acknowledge condition). The first byte is comprised
of seven address bits. These are used by the processor to select the PLL from
several peripheral components (address select). The LSB bit (R/W) determines
whether data are written into (R/W = 0) or read from (R/W = 1) the PLL.
In the data portion of the telegram during a WRITE operation, the MSB bit of the
first or third data byte determines whether a divider ratio or control information
is to follow. In each case the second byte of the same data type has to follow
the first byte. Appropriate setting of the test bits will decide whether the bandswitch byte or the auxiliary byte will be transmitted (see Table 5-7 Test modes on
page 40).
If the address byte indicates a READ operation, the PLL generates an acknowledge and then shifts out the status byte onto the SDA line. If the processor generates an acknowledge, a further status byte is output; otherwise the data line
is released to allow the processor to generate a stop condition. The status word
consists of three bits from the A/D converter, the lock flag and the power-on flag.
Four different chip addresses can be set by an appropriate DC level at pin AS
(see Table 5-6 Address selection on page 40).
While the supply voltage is applied, a power-on reset circuit prevents the PLL
from setting the SDA line to low, which would block the bus. The power-on reset
flag POR is set at power-on and if VCC falls below 3.2 V. It will be reset at the
end of a READ operation.

■ This value is only guaranteed in lab.
1). The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF).
2). This is the level of the RF unwanted signal (50% amplitude modulated with 1kHz) that causes a 1.1 kHz
FM modulation of the local oscillator and thus of the wanted signal; Vwanted = 100 dBµV; funwanted = fwanted +
5.5 MHz.
3). Local oscillator FM modulation resulting from I2C communication is measured at the IF output using a modulation analyser with a peak to peak detector ((P+ +P-)/2) and a post detection filter 30 Hz - 200 kHz. The I2C
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 1s.
4). This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz frequency deviation on the oscillator signal producing sidebands 30 dB below the level of the oscillator signal.
5). Channel S02 beat is the interfering product of fRFpix, fIF and fOSC of channel S02, fBEAT = 37.35 MHz. The
possible mechanisms are fOSC - 2 x fIF or 2 x fRFpix - fOSC.
6). Channel A-5 beat is the interfering product of fRFpix, fIF and fOSC of channel A-5; fBEAT= 45.5 MHz. The possible mechanisms are: fOSC - 2 x fIF or 2 x fRFpix - fOSC.
7). Channel 6 beat is the interfering product of fRFpix + fRFsnd - fOSC of channel 6 at 42 MHz.
8). The IF output signal stays stable within the range of the fref step for a low level RF input up to 120 dBµV.
9). N+5 -1 MHz is defined as the input level of channel N+5, at frequency 1 MHz lower, causing FM sidebands
30 dB below the wanted carrier.
10). Limits are related to the tank circuit used in the application board (Chapter 4). Frequency bands may be
adjusted by the choice of external components.
11). The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
VCC = 5 to 4.75 V (4.5 V) or from VCC = 5 to 5.25 V (5.5 V). The oscillator is free running during this measurement.
12). The frequency drift is defined as a change in oscillator frequency if the ambient temperature varies from
Tamb = 25 to 50 °C or from Tamb = 25 to 0 °C. The oscillator is free running during this measurement.

13). The switch-on drift is defined as a change in oscillator frequency between 5 s and 15 min after switch-on.
The oscillator is free running during this measurement.
14). The supply ripple susceptibility is measured in the application board (Chapter 4), using a spectrum analyser connected to the IF output. An unmodulated RF signal is applied to the test board RF input. A sinewave
signal with a frequency of 500 kHz is superposed onto the supply voltage (see 5.5.8 on page 49). The amplitude of this ripple is adjusted to bring the 500 kHz sidebands around the IF carrier to a level of 53.5 dBc referred
to the carrier.
15). This is the level of divider interferences close to the IF frequency. For example channel S3: fOSC = 158.15
MHz, 1/4 fOSC = 39.5375 MHz. Divider interference is measured with the application board (Chapter 4). All
ground pins are connected to a single ground plane under the IC. The LOWIN input must be left open (i.e. not
connected to any load or cable). The MIDIN and HIGHIN inputs are connected to a hybrid. The measured level
of divider interference are influenced by layout, grounding and port decoupling. The measurement results between various applications and the reference board could vary as much as 10 dB.
16). Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection
has to be greater than 60 dB for an IF output of 100 dBµV.
17). 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 IF output of 100 dBµV.
