STMicroelectronics STV0297E
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. It is fully compliant with ITU-T J83 Annexes A/C or DVB-C specification bitstreams (ETS 300 429, “Digital broadcasting systems for television, sound and data services - Framing structure, channel coding and modulation - Cable Systems”).| Part No. | STV0297E |
