Theater 314, 312, and 311 comprise a family of advanced QAM
and VSB demodulator ICs for the Digital Cable Ready and ATSC
environments.
The Theater 314 (T314) is configurable to operate in either
the ITU-J.83B/SCTE DVS-031 compliant 64 QAM or 256 QAM modes
used by digital cable systems, or the ATSC compliant 8VSB mode
used in digital terrestrial broadcasting. For digitally modulated
input signals (QAM or 8VSB), Theater 314 outputs a parallel or
serial MPEG compliant transport stream. For the out-of-band FDC,
Theater 314 performs the QPSK demodulation and provides a direct
digital interface (clock and data) to CableCARDsTM.
The Theater 312 (T312) offers the same functionality without
the FDC out-of-band receiver.
Theater 311 (T311) offers just the VSB demodulator function
for ATSC-compliant TV sets and satellite set-top-box applications.
Theater 314/312/311 demodulators enable equipment manufacturers
to deliver high performance products to consumers.
Theater 314/312 offers exceptional performance in the cable
environment. Their adaptive blind equalization algorithms allow
for fast acquisition times, while interference detection and
mitigation algorithms provide robust performance in the presence
of burst noise and adjacent channel interference. For digital
terrestrial reception, the advanced equalizer in the Theater
314/312/311 provides exceptional dynamic and static multi-path
performance. Superior performance in harsh environments is achieved
by the use of robust synchronization and equalization algorithms.
Furthermore, Theater 314/312/311's high level of integration
allows manufacturers to develop high performance, high functionality
products in a space and cost effective manner. |
