The TDA18275 features a fully integrated RF tracking filter as well as an integrated FM filter, and is available in a 5 x 5-mm 32-pin HVQFN package, reducing bill of materials costs. With an ultra-low noise figure of 3.5 dB and excellent return loss, the silicon tuner provides high sensitivity combined with enhanced immunity to analogue and digital ACI (adjacent channel interference), as well as stronger immunity to LTE and Wi-Fi interference. The 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 tuners, 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.
