Si2178 Worldwide Digital and Analog TV Tuner with Analog Demodulator Description The Si2178 integrates a PAL/SECAM/NTSC analog TV demodulator with a universal hybrid TV tuner supporting all worldwide digital and analog TV standards. The Si2178 requires no external balun and offers the lowest-cost BOM for a hybrid TV tuner with analog demodulator. By combining Silicon Labs' proven digital low-IF architecture with a 4th-generation RF front-end, the Si2178 maintains the highest performance that exceeds MOPLL-based tuners, including industry-leading 2nd-order distortion performance. Compared with competing silicon TV tuners, the Si2178 delivers an unprecedented level of front-end integration, resulting in the lowest number of external BOM components.
