Description

The Si2173 integrates a complete hybrid tuner with

analog TV demodulator supporting all worldwide

terrestrial and cable TV standards. Leveraging

Silicon Labs’ proven digital low-IF architecture, the

Si2173 extends the unmatched performance and

design simplicity of the original Si2170/1/2 while

further reducing footprint size. No external LNAs,

tracking filters, or SAW filters are used.

Compared with competing silicon tuners and discrete

MOPLL-based tuners, the Si2173 delivers superior

picture quality and a higher number of received

stations in crowded and near/far real-world reception

conditions. This unprecedented level of performance

in the field is enabled by a novel front-end

architecture which uniquely combines very high

linearity and low noise, delivering superior blocking

performance and higher sensitivity in the presence of

strong undesired channels and interference.

The Si2173 integrates the complete signal path from

antenna input to IF or analog video and sound

outputs.

MOPLL-based

hundreds of external components including external

LNAs, tracking filter varactors and inductors (unlike

competing silicon tuners), and SAW filters, resulting in

the simplest, lowest-cost BOM for a hybrid TV tuner

while improving performance.

DVB-T/C demodulator creates a complete terrestrial

and cable hybrid PAL/SECAM and DVB-T/C receiver.
