The TVP9900 ATSC Demodulator supports the reception of DTV broadcasts, includinghigh-definition TV (HDTV), in North America. The device supports all standard ATSCover-the-air and cable transmissions. The standalone demodulator is compatible withstandard ATSC tuners and a wide range of DTV video processors from TI and othersuppliers. Figure 1 shows the major components and connections of a DTV receiverusing the TVP9900.TVP9900 performance meets or exceeds the American Television StandardsCommittee’s (ATSC’s) A/74 recommendations, helping to simplify receiver design whileensuring high-quality imaging. Signal equalization covers the echo profile required byA/74 guidelines, and multipath and burst noise impairment performance demodulatesall Brazil ensembles—among the industry’s most demanding tests of multi-path performance—for improved signal reception over a greater transmission range. Figure 2on the following page shows how dramatically the TVP9900’s multi-path performance(top line) exceeds the A/74 requirements, ensuring high picture quality for the user.With its high level of system integration, the demodulator saves DTV manufacturersa significant amount, up to 20 percent, in the bill of materials for the receiver.
