The latest generation of Silicon Labs’ TV tuners—the Si21x7 family—improve the noise figure (NF) across all bands, return loss for a given NF, and linearity over an extended RF input power range over their predecessors. They also enhance channel selectivity in the presence of terrestrial blocks and in a fully loaded and/or tilted cable spectrum. The tuners’ high integration cuts bill of materials (BOM) costs. For instance, the tuner does away with the external balanced-to-unbalanced transformer (balun) on the RF input without degrading performance. Moreover, all tracking filter inductors are integrated, and built-in high-supply ripple tolerance eliminates the need for inductive power-supply filtering. Also integrated is a power-on reset monitor and optional single 3.3-V power-supply operation. Power consumption is less than 500 mW. Clearer, crisper reception of analog broadcasts is possible thanks to an ultra-low noise floor at the IF output, which boosts the video signal-to-noise ratio at the audio/video SoC’s analog demodulator output.
