Product Description
Overview
The TUA6120 'TORNADO' is a Direct Conversion Receiver for digital QPSK or 8PSKSat receiving systems in BICMOS technology. Compared to the conventional superheterodyne receiver the DCR architecture eliminates expensive RF-filters for image rejection and IF-filters for channel selection. Instead there are on-chip filters with selectable bandwidth integrated. The DCR system is the most promising approach for low-cost digital set-top boxes front ends. Via a LNA input stage, the RF signal is split into two rails. One is the buffered loopthrough RF output and, the other goes through a PGA (Programmable Gain Amplifier) to the I/Q- Mixers. The signal of the synthesizer VCO is multiplied to 4 x RF input frequency by an internal 3.8-8.6 GHz PLL system. To drive the mixers, this 3.8-8.6 GHz signal is split into quadrature components by a digital divider by 4. The VCO from which the oscillator signal is derived, never runs at the input frequency. The mixers are followed by 2 matched base-band PGA's and filters. The filter roll-off is selectable by software. Behind the filters external coupling capacitors eliminate undesired DC-components. Then follow another two base-band amplifiers and output buffers. The gain of the Q base-band amplifier is adjustable for compensation of I/Q gain impairment. The AGC detector senses the output level and generates the control signals for the PGAs and the RSSI information which is readable via the bus. The AGC system is optimized for best SNR and IM performance.

Functional Block Description
The main functions of the chip are split into a bipolar analog signal processing, a bipolar digital signal generation of 0/ 90 LO-signals, and a CMOS synthesizer. Extremely symmetrical layout with matched structures result in best phase and gain balance of the in-phase and quadrature-phase signals.
2.5.1
AGC-System
A complete AGC system is integrated. At the I/Q outputs an AGC detector monitors the output signal. It generates a dB-linear RSSI signal to the input level (Radio Signal Strength Indicator), and control signals to adjust the gain of the PGA's (Programmable Gain Amplifiers). PGA's are used because of their good intermodulation performance during gain control. The smallest AGC step is 0.5 dB, the AGC range is 63.5 dB. The internal AGC can be disabled. Then an external AGC voltage can be applied to pin 40.

Functional Description
2.5.2
LNA and RF-Buffer
The LNA is a 75 input amplifier with high linearity and low noise. At its output the RF signal is split. One part goes through the RF-buffer amplifier to a 75 RF-output.
2.5.3
PGA and I/Q-Mixers
The other part goes through a 48 dB control range PGA to the I and Q mixers. Both are of the double balanced mixer (Gilbert cell) type. A second PGA is arranged between the mixer output and the following baseband amplifier. For best performance the 0/ 90 LO-signals are fed to the mixers via open collector stages with well defined output impedance and levels.
2.5.4
Baseband Amplifiers and Filters
The 4 base band amplifiers are of wide-band operational type with high overshoot margin. The amplifiers have a fixed gain of 16 dB and 30 MHz-0dB bandwidth. The distribution of the whole DC-gain into two AC-coupled 16 dB amplifiers ensures that the base band amplifiers are not overloaded by a DC-voltage that may be caused by mixer offset or mixer LO feedback to the input. All 4 outputs can be disabled by bus control. In this state the outputs switch to low voltage and low impedance. Filters with programmable roll-off are inserted between the baseband amplifiers. The I and Q output voltages are programmable. The outputs are differential for best interference immunity.
2.5.5
Output Ports
The output ports are designed with open collector transistors for high current pull down and slow switching application.
2.5.6
Reference Voltage
The central reference voltage is a low noise high PSSR bandgap with approx. 2.4 V DC and low temperature drift.
2.5.7
Reference Oscillator
The reference oscillator operates with crystals from 1 - 16 MHz.

Functional Description
2.5.8
Crystal Oscillator Input/Output
This pin accepts an external quartz clock or supplies a quartz clock to the channel decoder. The frequency is controlled by a divider stage.
2.5.9
Synthesizer Loop filter
The synthesizer loop filter can be designed active by using an internal inverting BICMOS amplifier or passive (see Application Circuit on page 29). The loop filter input is internally connected to the phase detector / charge pump output. The BICMOS amplifier output may be disabled (high impedance) by bus.
2.5.10
Synthesizer VCO's
The synthesizer VCO's are symmetrical Colpitts type oscillators with high-Q internal tank circuits. The synthesizer VCO's oscillate at a programmable offset to the input frequency. This guarantees minimum oscillator pulling and self-mixing which results in undesirable DC offset voltage.
2.5.11
Phase Shift 0 / 90
To get minimum quadrature phase error, a digital generation of the 0/90 phase shifted local oscillator signal is implemented by a 3.8-8.6 GHz Johnson-counter / 4 . This counter is designed in high speed stacked ECL bipolar technology.
2.5.12
GHz VCO
This block consists of two on-chip bipolar LC-Oscillators (3.4-6.2 GHz and 6.0-8.6 GHz) controlled via on-chip PLL . The GHz VCO's oscillate at 4 times the input frequency and are current controlled. The resonant circuit is an on chip symmetrical inductor driven by differential pair amplifier whose current variable parasitic capacitance is used for frequency tuning. The used special multi-tanh gilbert cell makes a wide tuning range possible. The GHz VCO's are under control of a 3.8-8.6 GHz PLL system. The reference frequency of this system is the output of the synthesizer VCO divided by a programmable counter; variation is 200-315 MHz (depending on the selected synthesizer tuning range). At the same time this is the operating frequency range of the phase detector / charge pump. The high speed charge pump is completely on-chip and designed in BICMOS technology with an external loop filter bandwidth set to 9 MHz. The GHz VCO frequency is fed to the phase detector via the high speed ECL Johnson counter /4 and a lower speed programmable ECL counter.

Functional Description
2.6
GHz PLL
With conventional DCR systems the synthesizer VCO oscillates exactly at the desired receiving frequency. This is avoided in the TUA6120 'TORNADO' by a cascaded double PLL tuning system. The main benefits of this concept are:

accurate 0 / 90 generation of the LO signals for the RF input mixers no oscillator at input frequency programmable frequency offset of the synthesizer VCO referred to the RF input frequency and due to that a very low VCO oscillator pulling and self mixing due to crosstalk the possibility of splitting the tuning range into several bands.
These advantages are derived from a 2nd GHz PLL system with two VCO's at 4 x Fin. This 2nd GHz PLL system is located in the broken up feedback of the synthesizer PLL 1 between the VCO1 and the programmable counter input N1.

Cascaded PLL system
This location enables a shift of the synthesizer VCO1 to other frequencies, independent of the required input LO frequency of the RF mixers. In this case the synthesizer VCO must not oscillate at the required LO frequency of the mixer input. Nevertheless the synthesizer PLL is referred to the LO frequency of the mixer input which makes it easy to program the PLL because it is set exactly to the receiving frequency. Another benefit is the exact mapping of the PLL stepsize to the tuning frequency. This is not possible in a conventional PLL tuning system with the feedback of the VCO1 directly to the programmable counters N1, if the VCO1 is not running on the RF input

Functional Description frequency. This may become clear in the above concept, if the interrupted PLL 1 is closed and the LO I/Q output is cut off from node x. In this case step size and tuning frequency have additional terms of calculation. Depending on the system concept. they do not fit to the programmed values of the synthesizer PLL 1, because it is referred to the VCO1 and no longer to the LO I/Q output. (Following dependencies will become valid, Ftune = (N2 / R2)Fvco1 and Fstep = (N2 / R2)PLL1step ). The R2 and N2 counters of the GHz PLL enable a programmable frequency offset of the synthesizer VCO to the RF input as well as a splitting of the required RF tuning range. For the band splitting feature the counters R2 and N2 of the GHz PLL must be used with 2 different values (e.g. 4/2 and 4/3). As a result VCO1 will pass his range twice, while the LO I/Q output to mixer will have a tuning range which is split into 2 bands. In the feedback of the GHz PLL is located the high speed Johnson-counter / 4 (Q2) which acts as prescaler for the two 3.4 - 8.6 GHz VCO's and accurate 0 / 90 LO generator. The complete GHz PLL is designed in high speed ECL cascoded technology which enables counter frequencies up to 15 GHz, oscillator frequencies up to 10 GHz and phase detector / charge pump signal slopes of less then 100 ps.

Phase noise performance of application
The over all system phase noise at base band of the TUA 6120 is strongly dependent on several parameters : 1.programming of the 2nd PLL (GHz-PLL setting of the R2 and N2 counter) 2.programming of the 1st synthesizer PLL - receiving frequency (variation of the VCO steepness due to non linearity of the varicap), - phase detector current, - crystal frequency, - step size = Fref, - loop filter parameter. ( bandwidth ) A well balanced phase noise over the whole tuning range requires an optimized parameter programming of the synthesizer PLL for each receiving frequency - 1st you have to decide for the optimum loop filter bandwidth for your application. Narrow band loop filter : achieves better PLL outband phase noise at high frequencies offset but lower PLL inband phase noise at low frequency offset. Wide band loop filter : achieves better PLL inband phase noise at low frequencies offset but lower PLL outband phase noise at high frequency offset. - 2nd you have to decide for the crystal frequency for your application. Higher crystal frequency achieves better PLL inband phase noise. - 3rd you have to decide for the main stepsize for your application. Higher step size achieves better PLL inband phase noise. - 4th during programming the desired receiving frequency you have to set step size and phase detector output current for each frequency. This is necessary to compensate the non linearity of the varicap. All this is done in the above application circuit which obtains in conjunction with the TUA 6120 programming kit the following worst case phase noise values : Wide band loop filter 25 kHz, at tuning frequency 2150 MHz Offset Frequency Measured phase noise at base band 1 - 82 10 - 83 100 - 102 1000 - 108 kHz dBc/Hz

The GHz R/N-counter (register 00 bits 18,19,20; register 01 bits 10,11,12) are Johnson counters which may hang up if they start from a forbidden state. For a 2-3-4-5-6-7-8 counter chain forbidden states can appear at non binary divider values of 3, 5, 6, 7. Whereas the forbidden states in odd counter values correct themselves this will not happen with even counter values. Therefore the remaining counter value of 6 may come into an forbidden state if the programming is switched from a higher value (7 or 8) to 6, because the higher divider values include the forbidden states for counter value of 6. Therefore it is an absolute must to program the counter chain to e.g. 5 (which does not include forbidden states for 6) before it is set from higher values to 6. If this is not done a proper operation of the TUA6120 cannot be guaranteed. Reference frequency is 800 kHz with a 4 MHz crystal.
