This ATSC Demodulator IP is extracted from the production chip and silicon-proven IP core. It integrates a digital terrestrial ATSC receiver 8VSB demodulation and FEC, and a downstream interactive out-of-band (OOB) receiver (QPSK Demodulation). On-chip SRAMs avoid the need
for external memory components. In the case of OpenCable compliant products, this IP provides the support for a unidirectional (in-band and OOB downstream) configuration and enables a low-cost frequency-agile OOB by embedding an OOB tuner.
