Description
The Cascade2 is a multistandard demodulator and decoder for
terrestrial and cable TV reception. It is designed to support 8/16-VSB
in compliance with the ATSC Digital Television Standard as well as
OpenCable ITU-T J.83B in compliant 256/64 QAM and OOB QPSK
modes for Digital Cable Ready downstream reception.
The Cascade2 is designed to reduce system costs by integrating the
FAT channel demodulation of VSB, J.83 Annex B QAM and Audio
decoding (for analog channels) and the FDC QPSK channel
demodulation.
The small, high-performance Cascade2 is well suited for any system
designed to receive off-air and cable digital TV transmissions. This
includes stand-alone SDTV or HDTV sets, Set-Top Boxes, PC-TV
cards and data reception appliances.
The Cascade2 family ICs are produced in several combinations of
reception standards:
