Silicon TV Tuner Integrates RF, FM filters

NXP’s latest silicon tuner for worldwide terrestrial and cable TV reception features a fully integrated RF tracking filter and integrated FM filter. With a noise figure of 3.5 dB and excellent return loss, the TDA18275 tuner delivers the sensitivity combined with enhanced immunity required for analogue and digital ACI (adjacent channel interference), as well as stronger immunity to LTE and Wi-Fi interference. The hybrid silicon tuner, which operates from a single 3.3-V power supply, consumes 750 mW. The TDA 18275 comes in a 5mm-by-5mm, 32-pin HVQFN package.
