NXP Semiconductors has introduced a new generation of high-definition digital terrestrial silicon tuner, the TDA18211HD, which promises to raise the performance and lower the costs of STB applications. Touted to be the industry's first pure DVB-T silicon tuner, TDA18211HD eliminates the need for an external SAW filter and only requires one XTAL for a full Dual/PVR DVB-T front-end solution.

Faster time-to-market
Designed for the DVB-T standard, the new tuner reduces overall system cost and design cycles, enabling faster time-to-market while meeting the demanding performance and application requirements, the company said.

In addition, TDA18211HD offers easy multi-tuner configuration and easy on-board integration, as well as reduces tuner function size, affording manufacturers the ability to achieve smaller form factor devices. It also features fully integrated RF tracking filters, wholly incorporated IF selectivity, RF loop-through for easy STB implementation, fully integrated oscillators, built-in wideband gain control, 16MHz XTAL output buffer for single crystal applications, I²C interface compatible with 3.3V and 5V microcontrollers, single 3.3V supply and low power consumption, NXP said.

Smaller package, lesser BOM
"NXP has worked closely with its customers to develop the TDA18211HD, helping them meet their requirements of bringing more functionality and high-definition quality in a smaller package with reduced BOM, " said Guy Ducos, VP and general manager for TV front end and media interfaces at NXP.

NXP's TDA18211HD silicon tuner is sampling and is expected to be in mass production Q2 2007.
