Si2146

Worldwide Digital TV Tuner IC

Description

The Si2146 integrates a complete TV tuner

supporting all worldwide digital terrestrial and cable

TV standards. Leveraging Silicon Labs’ field proven

digital low-IF architecture, the Si2146 maintains the

unmatched performance and design simplicity of the

Si2143 while further reducing footprint size and bill of

materials cost. No external LNAs, tracking filters,

wirewound inductors or SAW filters are used.

Compared with competing silicon tuners and discrete

MOPLL-based tuners, the Si2146 delivers superior

picture quality and a higher number of received

stations in crowded and near/far real-world reception

conditions. The high linearity and low noise RF

front-end delivers superior blocking performance and

higher sensitivity in the presence of strong undesired

channels and interference.

The Si2146 integrates the complete signal path from

antenna input to IF output. Compared to traditional

discrete MOPLL-based tuners, the Si2146 eliminates

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 digital TV tuner.

nterfacing the Si2146 seamlessly with the Si2165

DVB-T/C demodulator creates a complete terrestrial

and cable DVB-T/C receiver.
