Abstract :
Two mixer-oscillator PLL ICs were developed to convert the desired TV-RF (45 MHz-1000 MHz) or TVSAT-RF (700 MHz-2500 MHz) to standard IF for TV or TVSAT sets and setstop baseband converters. Only two switched bands cover the complete frequency range of the TV or TVSAT channels. These ICs combine analog (mixer-oscillator) and a complete digital (PLL) functionality
