Silicon Laboratories has introduced a digital TV demodulator that combines satellite, terrestrial and cable digital video broadcast (DVB) functions in one highly integrated device. The Si2167 multimedia TV demodulator provides a small, single-chip, multi-standard demodulation solution, simplifying the design of integrated digital TVs (iDTV), set-top boxes (STB), personal video recorders (PVR), network interface modules, and professional video DVB receivers.

Today’s iDTV and STB makers rely on multiple demodulators to enable satellite (DVB-S/S2), terrestrial (DVB-T) and cable (DVB-C) reception in a single system. This approach adds cost and complexity to the system design. By supporting DVB-T/C/S/S2 in a single device, the Si2167 eliminates the need for multiple demodulators and simplifies both hardware and software design. The Si2167 IC’s DVB-T/C core is an enhanced and field-proven version of the Si2165 IC core, a market-leading terrestrial and cable demodulator that has shipped in high volumes during the last two years.
Available in a tiny 48-pin 7 mm x 7 mm QFN package, the Si2167 IC enables a small demodulator footprint for a DVB-S/S2 demodulator despite the inherent complexity of the DVB-S2 standard. The lower pin count simplifies the design process and significantly reduces the overall electrical component bill of material.

The Si2167 supports a seamless interface to Silicon Labs Si217x hybrid silicon tuner. Additionally, the Si2167’s flexible terrestrial and cable intermediate frequency (standard and low IF) interface is also compatible with any standard mixer oscillator phase-locked loop (MOPLL) based metal can tuners.
