Description

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

Skyworks' 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 fullyintegrated

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.
