Product Information

Back to top
The Si2151 is the industry's most advanced hybrid TV tuner supporting all worldwide terrestrial and cable TV standards for digital and analog TV reception. Leveraging five generations of field-proven hybrid TV tuner technology, the Si2151 delivers the same or better RF performance as Silicon Labs' Si2157 hybrid TV tuner while further reducing footprint size and bill of materials cost.

Available in an industry-leading 3x3 mm QFN package, the Si2151 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. 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 provides several dB of improved reception performance compared to competing solutions. Additionally, a software-selectable cable mode offers optimized return loss.

The Si2151 delivers exceptional picture quality and a higher number of received stations when compared to other silicon tuners. Incorporating worldwide field experience from five prior hybrid tuner generations in mass production, the Si2151 delivers the highest tolerance to real-world reception conditions.
