Si2146

Worldwide Digital TV Tuner IC

Description

Features

- Worldwide digital TV tuner

The Si2146 integrates

complete TV tuner

- ATSC/QAM, DVB-T/T2/C, ISDB-T/C, DTMB

- 42-1002 MHz frequency range

- Compliance to A/74, NorDig, D-Book, C-Book,

ARIB, OpenCable™ specifications

- Best-in-class real-world reception

- Exceeds MOPLL-based tuners

- Highly integrated, lowest BOM

- No SAW filters or wirewound inductors required

- Integrated LNAs and complete tracking filters

- No alignment, tuning or calibration required

- Digital low-IF architecture

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.

- Integrated channel select filters

- Flexible output interface

- DLIF to digital TV demodulator or SoC

- 3.3 and 1.8 V power supplies

- Standard CMOS process technology

- 5 x 5 mm, 32-pin QFN package

- RoHS compliant

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.

Applications

- Digital ½-NIM and full-NIM

- iDTV (Integrated Digital TV)

- Digital terrestrial and cable STB

- Digital PVR and DVD recorder

Interfacing the Si2146 seamlessly with the Si2165

DVB-T/C demodulator creates a complete terrestrial

and cable DVB-T/C receiver.
