Worldwide Hybrid TV Tuner IC with Analog Demodulator

Description

Features

- Worldwide hybrid TV tuner

The Si2176 integrates a complete hybrid tuner with

analog TV demodulator supporting all worldwide

terrestrial and cable TV standards. Leveraging

Silicon Labs’ field proven digital low-IF architecture,

the Si2176 maintains the unmatched performance

and design simplicity of the Si2173 while further

reducing footprint size and bill of materials cost. No

external LNAs, tracking filters, wirewound inductors

or SAW filters are used.

- Analog TV: NTSC, PAL/SECAM

- Digital TV: 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, EN55020, OpenCable™ specifications

- Best-in-class real-world reception

- Exceeds discrete 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

Compared with competing silicon tuners and discrete

MOPLL-based tuners, the Si2176 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

- Analog TV demodulator

- Superior video SNR performance

- Overmodulation and ICPM tolerant

- Customizable ATV and DTV channel filters

- Flexible output interface

- CVBS + SIF/AF to audio/video processor or SoC

- 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 Si2176 integrates the complete signal path from

antenna input to IF incorporating Silicon Labs' third

generation field-proven analog demodulator to

provide analog video and sound outputs. Compared

to traditional discrete MOPLL-based tuners, the

Si2176 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

hybrid TV tuner.

Applications

- Hybrid ½-NIM, ¾-NIM and full-NIM

- iDTV (Integrated Digital TV)

- Digital terrestrial and cable STB

- Hybrid PVR and DVD recorder

Interfacing the Si2176 seamlessly with the Si2165

DVB-T/C demodulator creates a complete terrestrial

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