It quite true that Silicon Tuner ICs will be the perfect replacement of Analog Tuners this has all the advantages of the digital tuning with the digital displays or digital devices. In fact designers were really wanted to have such kind of device which be easily interfaced in the design with improvement in the user friendliness.
This recalls me designing of Analog VHF UHF tuners in the year 1980. THe LO and tuned circuits tuned by varactor diodes BB115,116.They were made on glossepoxy boards with the inductors made on the board's copper area for UHF portion.Matching the various stages over the whole band and setting the tuning is the interesting portion of it. This item will have its market for life time.
"Designing silicon TV tuners that matched MOPLL performance levels was the main hurdle for adoption..."
I'm not sure it was that, so much as it was finding ways around the patents of early silicon tuner makers like Microtune.
