Silicon Labs showed continuing support for analogue TV standards, as it announced a family of hybrid TV tuners.
The family covers just about every combination of digital reception, analogue reception, and analogue demodulation β all in the same pin-compatible 4x4mm QFN-28.
βAlthough a few countries have successfully switched to digital-only broadcasts, more than 95% of todayβs TVs must continue to support analogue broadcast reception,β said SiLabs. βIn addition, analogue-only TVs prevalent in China, India and Southeast Asia represent about 20% of the global TV market. For these regions, analogue TV tuners often require a high tolerance to non-standard analogue TV signal conditions.
There is close competition in the TV tuner market between SiLabs, NXP, MaxLinear and Sony.
