... General Description The TUA6020 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 1024 MHz in increments of 31 ...
