ISDB-S3 compatible demodulator chip for 4K and 8K satellite digital broadcasts

Sony commercialized what it claims as industry's first demodulator LSI and tuner modules meeting ISDB-S3 (Integrated Services Digital Broadcasting for Satellite, 3rd generation) standard for 4K and 8K satellite digital broadcasting. ISDB-S3 capable of transmitting twice the amount of data compared to conventional ISDB-S standard. The ISDB-S3 standard expands the upper limit for reception frequency to 3224 MHz, from 2070 MHz with the conventional standard.

Sony to ship sample quantities of this semiconductor device in the month of September. In Japan test broadcasting of ISDB-S3 4K and 8K is scheduled to start in the month of August and full-scale broadcasting is slated to begin in December 2018.

CXD2857ER demodulator LSI is designed with proprietary reception algorithms and error correction technology to offer high-quality signal reception. The LSI also features reduced power consumption, and because it is compatible with all digital TV broadcast standards currently in use in Japan, it enables TV and set-top box manufacturers to make their products more compact by freeing them from the need to incorporate different component parts for different standards, says Sony.

Sony's new SUT-PJ/CJ series tuner modules feature built-in noise reduction powered by the use of CXD2868ER, a newly developed silicon tuner IC that features Sony's proprietary noise reduction circuitry. Also this silicon tuner IC is capable of receiving the three Japanese TV broadcasting signals (terrestrial digital, BS/CS digital) all in one IC and retains the same size and power consumption levels as its predecessor.
