TDA18274 Features Full Integration of RF Filter and State-of-the-Art LTE Immunity

EINDHOVEN, NETHERLANDS — NXP Semiconductors N.V. (NASDAQ: NXPI) today 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.

Additional features in the TDA18274 high-performance silicon TV tuner include:

  • RF input bandwidth extended to 1 GHz in anticipation of updates to OCUR specification
  • Flexible low-IF output interface from 3 to 7.5 MHz, enabling high compatibility with SoCs
  • Best-in-class phase noise performance; return loss higher than 8 dB with 4 dB noise figure
  • Two (2) General Purpose Output (GPO) pins
  • No need for external LNA, SAW filters and extra balun, or for manual alignment
  • Reduced Bill of Materials to less than $0.30, including eBoM, connector and shielding
  • Availability in both 48-pin (7-mm x 7-mm) and 40-pin (6-mm x 6-mm) HL/HVQFN packages

Standards targeted with the TDA18274 include:

  • All analog (PAL, SECAM, NTSC) and digital TV standards worldwide (DVB-T/T2, DVB-C/C2, ATSC, ISDB-T, DTMB, J.83B)
  • Specifications including ARIB STD-B21 (Japan, Brazil), A74-2010 (US), C-Book (EU), D-Book 7 (UK), E-Book (EU), CENELEC EN55020 (EU), NorDig 2.2 (EU) and OCUR (US)
