Product Description
The TUA6034, TUA6036 ’TAIFUN’ device combines a mixer-oscillator block with a
digitally programmable phase locked loop (PLL) for use in TV and VCR tuners and in set-
top-box applications.
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, 125, 142.86 or 166.7 kHz. The tuning process is controlled by a microprocessor
via an I
2C bus. The device has 5 output ports, one of them (P4) 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 I
2C bus.
