I finally found an ATSC demodulator chip with a datasheet. The TI TVP9900
Claims to exceed A/74 and have "Superior Multipath Performance Demodulating for Brazil Ensembles A Through E". Supports "smart" antennas. (I'm not convinced that smart antennas are worth bothering with. Every tuner would need its own antenna, and it sounds like the antennas aren't that great. But hey, having support for it is better than not having it.) US$6 in quantity "1ku" (does that mean 1000?) http://focus.ti.com/docs/prod/folders/print/tvp9900.html http://www.digitaltvdesignline.com/showArticle.jhtml?printableArticle=true&articleId=199701903 I was hoping the datasheet would tell how to get the coefficients being used for the equalizer taps, but it doesn't appear to even mention them. I can't find much on sibling chips TVP9007 or TVP9010. It appears that the TVP9007 includes a mpeg decoder. It looks like it would be fairly straightforward to build an antenna-to-Ethernet box. _______________________________________________ Open-hardware mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-hardware
