A fully integrated 1.8 V LDO enables single supply operation, while a dual supply option offers additional system flexibility. While competing solutions may also eliminate the balun, they suffer degradation in NF and second-order distortion, compromising reception. The Si2141 delivers unprecedented integration with no external balun, tracking filters, LNAs, SAW filters or inductive power supply filtering.Īvailable in an industry-leading 3x3 QFN24 package, the Si2141 eliminates 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. Leveraging five generations of field-proven TV tuner technology, the Si2141 delivers improved RF performance over our Si21x7 TV tuners while further reducing footprint size and bill of materials cost. The Si2141 is the industry's most advanced silicon TV tuner IC supporting all worldwide terrestrial and cable TV standards for digital and analog TV reception.
