    7. QAM DEMODULATOR – STV0297E 7.1. General Desription The STV0297E is a complete single-chip QAM (quadrature amplitude modulation) demodulation and FEC (forward error correction) solution that performs sampled IF to transport stream (MPEG-2 or MPEG-4) block processing of QAM signals. It is intended for the digital transmission of compressed television, sound, and data services over cable.

  • Page 16: Features

    Japanese DBS systems require a transport stream multiplex frame (TSMF) layer to carry digital signals over cable systems. When the recovered transport stream is a multiplex frame, the STV0297E post-processes it to extract a single transport stream. Automatic detection of the TSMF layer is provided. The chip integrates an analog-to- digital converter that delivers the required performance to handle up to 256-QAM signals in a direct IF sampling architecture, thus eliminating the need for external downconversion.
