(PLL), with a mixer-oscillator block including two balanced mixers and oscillators for use in TV and VCR tuners. The PLL block with four 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 three output ports. A flag is set when the loop is locked it can be read by the processor via the I2C bus. The mixer-oscillator block includes two balanced mixers (one mixer with highimpedance input and one mixer with a balanced low-impedance input), two frequency and amplitude-stable balanced oscillators for LOW/MID and HIGH, an IF amplifier, a low-noise reference voltage source, and a band switch. 2.2 Features General Suitable for analog and digital terrestrial TV tuner Full ESD protection Wireless Components Mixer/Oscillator High impedance mixer input for LOW/MID band Low impedance mixer input for HIGH band 4 pin oscillator for LOW/MID band 4 pin oscillator for HIGH band IF-Amplifier balanced SAW preamplifier Low output impedance PLL PLL with short lock-in time High voltage VCO tuning output Fast I2C bus 3 NPN bandswitch buffers Internal LOW-MID/HIGH switch Lock-in flag Power-down reset 2-2 Specification, March 2000 TUA6020 preliminary Product Description Programmable reference divider ratios: 24, 64, 80, 128 Programmable charge pump current 2.3 Application 2.4 Package Outlines Wireless Components The IC is suitable for PAL tuners in TV- and VCR-sets or set-top receivers for analog TV and Digital Video Broadcasting.

Filters between tuner input and IC separate the TV frequency signals into two bands. The band switching in the tuner front-end is done by using two or three port outputs. In the selected band the signal passes a tuner input stage with MOSFET amplifier, a double-tuned bandpass filter and is then fed to the balanced mixer input of the IC which has in case of LOW / MID a high-impedance input and in case of HIGH 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 high-impedance output pair by means of a parallel tuned circuit. The following SAW preamplifier 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 to a reference frequency fref = 31.25, 50, 62.5 or 166.7 kHz.This frequency is derived from a unbalanced, low-impedance 4 MHz crystal oscillator (pin XTAL) divided by R = 128, 80, 64 or 24. The phase detector has two outputs that drive two current sources of opposite palarity as 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 I- 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 pullup resistor at TUNE and external RC circuitry). The charge pump output is also switched into the high-impedance state if the control bit T0 = 1. 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. TUNE 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). 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. Wireless Components 3-8 Specification, March 2000 TUA6020 preliminary Confidential Functional Description The software-switched ports PLOW, PMID and PHIGH are general-purpose open-collector outputs. The test bit T1 = 1, switches the test signals fref (i.e.fXTAL / 64) and fdiv (divided input signal) to PLOW and PMID respectively. The lock detector resets the lock flag FL if the width of the charge pump current pulses is wider 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 == I P (KVCO / fXTAL) =(C1+C2) / (C1C2) where IP is the charge pump current, KVCO the VCO gain, fXTAL the crystal oscillator frequency and C1, C2 the capacitances in the loop filter (see Figure 4-1 Evaluation Board on page 2). As the charge pump pulses at i.e. 62.5 kHz (= fref), it takes a maximum of 16=s 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=s for FL to be set after the loop regains lock. 3.4.3 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), while pin SDA functions as an input or output depending on the direction of the data (open collector, external pull-up resistor). Both inputs have 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 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 10) should be referred to 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 (chip 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. Wireless Components 3-9 Specification, March 2000 TUA6020 preliminary Confidential Functional Description 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 the lock flag and the power-on flag. Four different chip addresses can be set by appropriate DC level at pin AS (see Table 5-6 Address selection on page 11). While applying the supply voltage, 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 when VCC falls below 3.2 V. It will be reset at the end of a READ operation.
