Description

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 Skyworks' 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 fullyintegrated

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.
