TUA6030, TUA6032
Wireless Components
Specification, January 2002
2.1
Overview
The TUA6030, TUA6032 devices combine a mixer-oscillator block with a digi-
tally 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-imped-
ance 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 digit-
ally programmable phase locked loop. With a 4 MHz quartz crystal, the PLL per-
mits 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.
