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
5
th
-generation RF front-end, the Si2177 maintains the
highest performance that exceeds that of MOPLL-based
tuners, including industry-leading 2
nd
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
2
nd
order 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.
