Micronas, ATI Introduce DTV Chips
has launched its line of 8VSB/QAM/QPSK/NTSC demodulator products, the first line of DTV chips based on its 2004 acquisition of LINX Electronics.
Designed for DTVs, set-top-boxes, PCs, DVD records, PVRs and tuner models, the silicon complies with the FCC tuner mandate, which requires CE manufacturers to integrate digital receivers into TVs and some digital consumer electronics devices.
German-based Micronas built its primeD technology DRX-H to boost DTV reception performance. Instead of just filtering echoes out, primeD technology improves reception by combining multiple echoes to create a single, stronger signal. Four versions of the DRX-H are available, all in a 14x20mm 128 pin QFP range.
"Unlike most competitors' implementations, Micronas' DRX-H demodulator does not simply discard undesired echoes but combines them in a unique patented manner with the desired signal which results in superior performance under realistic field conditions," said Hans-Juergen Desor, vice president, consumer products, Micronas.
Also this week, Ontario, Canada-based ATI
launched its Xilleon 240, an integrated TV-on-Chip designed for DTV sets in the North American and Korean markets.
Xilleon 240 includes a MIPS CPU, a digital front end capable of demodulating and decoding 8-VSB for ATSC terrestrial broadcasts or 64/256 QAM for digital cable, and HD/SD capable MPEG video and audio decoder, an NTSC video decoder video decoder with a 3D comb filter and a video scaler and deinterlacer.
