High sensitive TV tuner IC TDA18275 immune to interference
NXP Semiconductors N.V. has unveiled its latest new TV tuner chip TDA18275 for terrestrial and cable TV reception. The TDA18275 integrates RF tracking filter and FM filter, and is available in a small 5-mm x 5-mm 32-pin HVQFN package. Offering a very low noise figure of 3.5 dB and the best return loss, the TDA18275 picks weak signals and is also immune to analog and digital ACI (adjacent channel interference), and to LTE and Wi-Fi interference. TDA18275 hybrid silicon tuner operates from a single 3.3V power supply while consuming only 750 mW. Now sampling with qualified customers, the TDA18275 is scheduled for volume production in July 2013.
“For TV set manufacturers replacing older can tuners with silicon tuners, NXP offers the most cost-effective high-performance silicon tuner solutions, optimized for direct on-board integration. With the TDA18275 hybrid silicon tuner, we continue to raise the bar in power efficiency and robustness, while reducing overall application size and BOM costs,” said Fabrice Punch, international product marketing manager, NXP Semiconductors. “NXP’s expertise in RF and analog and digital TV standards, combined with our strong manufacturing supply chain, positions us as a highly reliable partner – now supplying silicon tuners to 13 of the top 15 TV brands in the world.”
