Product Information

The Si2141 is the industry's most advanced digital TV tuner supporting all worldwide terrestrial and cable TV standards for digital TV reception. Leveraging five generations of field-proven digital TV tuner technology, the Si2141 delivers the same or better RF performance as Silicon Labs' Si2147 digital TV tuner while further reducing footprint size and bill of materials cost.

Available in an industry-leading 3x3 mm QFN 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. 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 Si2141 provides several dB of improved reception performance compared to competing solutions. Additionally, a software-selectable cable mode offers optimized return loss.

The Si2141 delivers exceptional picture quality and a higher number of received stations when compared to other silicon tuners. Incorporating worldwide field experience from five prior digital tuner generations in mass production, the Si2141 delivers the highest tolerance to real-world reception conditions.
