General Description

The STi5162 is the latest in the family of STBus set-top box ICs providing high-performance, low-cost system-on-chip (SoC) for MPEG processing in digital terrestrial STBs. It is derived from the STi5107, with the addition of a DVB-T COFDM demodulator and supports multiple platforms using a unified architecture.
