Description

A universal hybrid TV tuner with an integrated

PAL/SECAM/NTSC analog TV demodulator, the Si2177

supports digital and analog reception for all worldwide

terrestrial and cable TV standards. By combining

Skyworks’ proven digital low-IF architecture with a 5thgeneration

RF front-end, the Si2177 maintains the highest

performance that exceeds that of MOPLL-based tuners,

including industry-leading 2nd order distortion performance.

Pin- and API-compatibility to the previous generation

minimize customers’ development effort.

The Si2177 delivers unprecedented integration with no

external balun, tracking filters, LNAs, SAW filters, or

inductive power supply filtering. While other solutions may

also eliminate the balun, they suffer degradation in NF and

2nd order distortion compromising reception. Skyworks’

proprietary and field-proven architecture delivers not only

an optimized BOM but also world-class system

performance. Options for single or dual supply and internal

power-on reset are included. A harmonic rejection mixer

delivers outstanding immunity to Wi-Fi and LTE

interference, replacing the need for external filtering.

For advanced digital terrestrial TV reception, DVB-T2 and

DVB-C2 constellations demand outstanding phase noise

specifications, and the Si2177 rises to the challenge,

delivering industry-leading integrated phase noise.

Additionally, a software-selectable cable mode offers

optimized return loss.

The Si2177 delivers exceptional picture quality and a

higher number of received stations when compared to

other solutions. Incorporating worldwide field experience

from four prior tuner generations in mass production, the

Si2177 delivers the highest tolerance to real-world

reception conditions.
