Si2151/41 6th Generation Silicon TV Tuner ICs 

The Si2151/41 are the industry's most advanced silicon TV tuner ICs supporting all worldwide terrestrial and cable TV standards for digital and analog TV reception. Leveraging five generations of field-proven TV tuner technology, the Si2151/41 deliver improved RF performance over Silicon Labs' Si21x7 TV tuner family while further reducing footprint size and bill of materials cost. The Si2151/41 deliver unprecedented integration with no external balun, tracking filters, LNAs, SAW filters or inductive power supply filtering.

Available in an industry-leading 3x3 mm QFN package, the Si2151/41 eliminate the need for an external balun, LNAs, SAW filters, and inductive power supply filtering to deliver the lowest-cost, most design-friendly and area-efficient solution available today. While competing solutions may also eliminate the balun, they suffer degradation in NF and second-order distortion, compromising reception. A fully-integrated 1.8 V LDO enables single supply operation, while a dual supply option offers additional system flexibility. Increased immunity to LTE interference and a harmonic rejection mixer with outstanding immunity to Wi-Fi interference eliminate the need for external filtering.

For advanced digital broadcast standards with high-order constellations, such as DVB-T2 and DVB-C2, the superior integrated phase noise of the Si2151/41 provides industry-leading reception performance compared to competing solutions. The Si2151/41 deliver exceptional picture quality and a higher number of received stations when compared to other silicon TV tuners.
