Description

Built upon six generations of field-proven TV tuner

technology, the Si2124 is Skyworks’ first digital set-top box

(STB) tuner designed specifically for digital terrestrial STB

applications. Like the previous generations of Skyworks'

digital TV tuners, the Si2124 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

Si2124 delivers the lowest-cost, most design-friendly and

area-efficient digital terrestrial 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 loopthrough

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 Si2124’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, the Si2124's superior

integrated phase noise delivers industry-leading reception

performance.

The Si2124 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 Si2124 delivers the highest tolerance

to real-world reception conditions.
