Si2151/41 第 6 代硅电视调谐器 IC

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

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 eliminates 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 Si2151/41 devices provides industry-leading reception performance as well as exceptional picture quality and a higher number of received stations compared to other silicon TV tuners.
