NXP Announces Breakthrough Silicon TV Tuner Fully Optimized for On-Board Design

NXP Semiconductors has announced the TDA18274 - a groundbreaking high-performance silicon tuner for worldwide terrestrial and cable TV reception. Supporting all analog and digital TV standards, the TDA18274 hybrid silicon tuner is optimized for direct "on-board" designs and will be available in two versions: a 48-pin HLQFN package version featuring fully integrated RF filters, and a 40-pin HVQFN package version with external UHF and VHF filters. The TDA18274 is also optimized for multi-tuner applications, eliminating the need for a companion chip by integrating the RF splitter function, enabling shared use of a single 16-MHz crystal via a crystal oscillator output buffer, and providing a control interface that can manage up to 4 tuners via four I2C addresses. Significantly, the TDA18274 provides strong immunity to LTE interference - a mounting concern in the TV industry, as ultra-fast LTE networks using frequencies formerly allocated to analog television are rolled out worldwide, and consumer adoption of 4G LTE handsets continues to grow. The TDA18274 also offers improved handling of DTG D-Book 7 requirements, as well as strong immunity to other spurious and field interferences including EMI (electromagnetic interference). NXP will demonstrate the TDA18274 at 2012 International CES in Las Vegas, Nevada (Central Plaza 8) from January 10 - 13. Samples are available now for selected customers.
