ST unveils single-chip DVB-T tuner

STMicroelectronics NV (Geneva, Switzerland) has introduced the STV4100 terrestrial tuner, a direct conversion (zero-IF) receiver with quadrature outputs intended for digital TV broadcasting. With digital switchover now imminent in many territories, ST said its STV4100 silicon tuner aims to meet demand for terrestrial set-top boxes, integrated digital televisions (iDTVs), and PCTVs.

With the STV4100, ST notes that it provides complete chipsets for DVB-T receivers, including the tuner and a choice of demodulators, MPEG decoders and combined demodulator/decoder ICs.  The STV4100 complies with all DVB-T standards such as DTG, Nordig Unified v2.0, and Digitenne.

The STV4100 can be used with the STV0362 demodulator to create a generic STB front end for a decoder IC such as the STi7105. Alternatively, the device can be used with one of ST's combined demodulator/decoder ICs such as the STi516x SD MPEG2 decoder family or the forthcoming STi5267 and STi7167 H.264 decoders for SD and HD applications, respectively.
