NXT2003 and NXT2004

The NXT2003 and NXT2004 are ATSC receiver ICs. The NXT2003 DTV Cable and Terrestrial Receiver is configurable to work in either the ATSC compliant 8-VSB reception mode for terrestrial broadcasting, or in the OpenCable™/ITU J.83B/SCTE DVS-031/DOCSIS™compliant 64/256-QAM and QPSK modes for Digital Cable compatbile downstream reception.

The NXT2003 is designed for a variety of applications including off-air and cable digital television receivers, set-top boxes, PCTV, and datacast appliances, where cost and industry-leading performance are a must.

The NXT2003 is based on the same VSB and QAM demodulator technology available in the NXT2004. In addition, it incorporates the QPSK forward datachannel receiver, all in one highly integrated solution. The FDC receiver provides a direct digital interface to OpenCable™ compliant Point of Deployment (POD) modules. NXT2004 is identical to NXT2003 with the FDC receiver removed and packaged in a 100 LQFP.
