Silicon tuner adoption in TVs and other electronics will help drive down costs, which is a pressure needed for manufactures to stay cost competitive. Electronics have to continually get cheaper for more people to buy them, unless any major breakthrough is achieved to justify high prices. This is something I will be paying close attention to.

You need a tuner for each channel and an SOC with enough horsepower to decode both (or all three) channels.

During 1980's the TV signals received with Yagi antennas.A low noise combined with good varicaps with highly stable tuning voltage with good AFC/AGC circuits were required. Nowa days the specifications required are not so tight as the signals are strong and almost from cable and dish. A lot of architectures are possible and many designs will evolve in future.

How do you achieve PIP functionality with Digital tuner? It will be nice if it is possible to tune to even three or more channels simultaneously.

Great article on the evolution of silicon tuners. I must say I got a chuckle from the phrase "Digital SAW" -- an oxymoron that only a receiver designer would understand :)

I continue to follow the development of silicon tuners for TV with great interest, and still find myself wishing for minimum performance requirements on TVs so that better tuning is achieved.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
