The TV industry is moving towards the full-scale adoption of silicon tuners, and NXP Semiconductors is paving the way. The company's TDA18272 silicon tuner is designed for worldwide terrestrial and cable TV reception, supporting all the analogue and digital TV standards worldwide. Helping TV manufacturers get ready for next-generation TV sets, the company has shipped over 40 crore silicon tuners to date, driving system optimised silicon tuners. The TDA18272 represents NXPs fourth generation of silicon tuner design.

With silicon tuners poised to replace traditional MoPLL based CAN tuners in all applications, the TDA18272 addresses the growing global demand for highly-integrated, low-power and ultraslim TV architectures. Possessing a very small form factor, the TDA18272 comes in a 40-pin, 6mm x 6mm package which facilitates the design of ultraslim, flat panel TVs. Featuring a high level of integration, the TDA18272 incorporates RF tracking filters, oscillators, IF selectivity and wide band gain control, eliminating the need for external components such as SAW filters or Baluns. With TDA18272, NXP introduces a master/slave architecture for optimising the design of multi-tuner applications. The TDA18272 is manufactured under NXP's zero defect program which enables manufacturers to simplify product assembly and supply-chain management.

"Production-proven silicon tuners such as the TDA18272 will swiftly replace CAN tuners, just as transistors replaced vacuum tubes during the 60s. TV broadcast tuners are evolving rapidly, replacing old radio RF analogue circuits with silicon tuners. NXP's silicon tuners speed up the design-in process, save production costs and improve performance. They also save space in multi-tuner systems and reduce energy requirements," said Robert Murray, general manager and senior director, product line TV front end, at NXP Semiconductors.

"Traditional STB and TV tuners have reached a stage of maturity in size and price, making further technological progress difficult. To overcome this, we are continuously looking at highly integrated solutions which meet attractive system cost. Silicon tuners which integrates the tuner function and channel filters are such building blocks. The NXP silicon tuner technology helps us to design products which meet current market requirements. Because of the high level of integration, they are also suited for multi-tuner applications," said Veit Armbruster, VP of development, NuTune.
