The Si2144 is the industry's most advanced digital Set-Top Box (STB) tuner supporting all worldwide cable and terrestrial TV standards for digital TV reception. Like the previous generations of Silicon Labs' digital TV tuners, the Si2144 maintains very high linearity and low phase noise to deliver superior picture quality compared to competing silicon tuners.

Available in an industry-leading 3x3 mm QFN package, the Si2144 delivers the lowest-cost, most design-friendly and area-efficient digital STB solution available today. A fully-integrated RF front-end eliminates the need for an external balun, LNAs, SAW filters, and inductive power supply filtering. Also included is a fully-integrated loop-through function with a zero-power mode switch (ZPS) for additional board area and BOM savings. An on-chip 1.8 V LDO enables single-supply operation, while a dual-supply option offers additional system flexibility. The Si2144’s excellent immunity to LTE interference and 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 Si2144's superior integrated phase noise delivers industry-leading reception performance.

The Si2144 delivers a higher number of received stations compared to other silicon tuners. Incorporating worldwide field experience from prior generations of digital tuners in mass production, the Si2144 delivers the highest tolerance to real-world reception conditions.

Symmetry Electronics is an authorized Silicon Labs distributor.
