Si2177

Worldwide Digital and Analog TV Tuner

with Analog Demodulator

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 Silicon

Laboratories’ proven digital low-IF architecture with a

highest performance that exceeds that of MOPLL-based

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

distortion

compromising reception.

Silicon

Laboratories’ 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.
