Si2167-D DVB-S2X/S2/T/C/S Digital Demodulator

Si2167-D multimedia TV demodulators combine satellite, terrestrial and cable digital-video broadcast (DVB) functions in one highly integrated device. Si2167-D devices are a single-chip, multi-standard solution that simplify the design of complex video front-ends now common in iDTV and STB designs.

Si2167-D solutions integrate digital demodulators for first and second generation DVB standards, DVB-/T/C/S and DVB-S2X/S2, respectively, in a single advanced CMOS die. Leveraging our proven digital demodulation architecture, Si2167-D devices achieve excellent reception performance for each media while significantly minimizing front-end design complexity, cost and power dissipation. Connecting Si2167-D demodulators to a hybrid TV tuner or digital only tuner, such as our Si2177, Si2151 and Si2141 tuners, results in a high-performance and cost optimized TV or STB front-end solution.
