TUA6024
Wireless Components
Specification, December 1999
2.1 General Description
The TUA6024 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 programma-
ble phase locked loop. With a 4 MHz quartz crystal, the PLL permits precise set-
ting of the frequency of the tuner oscillator up to 900 MHz in increments of
31.25, 50 or 62.5 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 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.
