TUA6024-2
Wireless Components
Specification, July 2001
2.1
General Description
The TUA6024-2 device combines a digitally programmable phase locked loop
(PLL), with a mixer-oscillator block including two balanced mixers and oscilla-
tors for use in TV and VCR tuners.
The PLL block with four selectable chip addresses forms a digitally programm-
able 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 micropro-
cessor 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 high-
impedance input and one mixer with a balanced low-impedance input), two fre-
quency and amplitude-stable balanced oscillators for LOW/MID and HIGH, an
IF amplifier, a low-noise reference voltage source, and a band switch.
