Funny...I was not aware that the FCC had imposed "stringent digital TV
tuner standards" on the CE industry. The things you find out in magazines...

LSI Single-Chip Tuner for ATSC DTV
LSI Logic has announced a new single-chip RF tuner, the DPS7040, that
Mike Paxton, a multimedia analyst at In-Stat/MDR claims, "meets the
FCC's stringent digital TV tuner standards and provides manufacturers
with a single-chip RF tuner solution for the next-generation of
television appliances." The tuner receives TV signals from 48 to 870 MHz
and downconverts them to an intermediate frequency (IF) in the 30 to 60
MHz range.
According to the LSI news release
<http://stg.syndnet.thomsonfn.com/InvestorRelations/PubNewsStory.aspx?partner=5333&storyId=117539>
"The synthesizer and oscillator sections have been designed to exhibit
exceptional close-in phase noise, making this IC an ideal choice, for
applications that require support for DTV standards." The chip includes
a low-noise amplifier (LNA), a variable gain IF amplifier, RF automatic
gain control, filters, mixers and oscillators.
Ravi Shenoy, Director of Analog and RF Technologies at LSI Logic
explained, "The DPS7040 RF tuner permits manufacturers to cut space,
minimize component cost and hit the market windows required by the FCC
mandate. The unique design of our RF tuner chip means that there is no
need for specific radio frequency (RF) alignments, giving digital flat
panel, PCTV Card and STB manufacturers much easier and quicker
development of applications."
A search of www.lsilogic.com <http://www.lsilogic.com> did not provide
any additional detail or specifications for the chip, so it is
impossible to determine if it meets the ATSC Recommended Practice A/74
Receiver Performance Guidelines <http://www.atsc.org/standards/a_74.pdf>.

===================================
"A strict observance of the written laws
is doubtless one of the high duties of a
good citizen, but it is not the highest.
The laws of necessity, of self-preservation,
of saving our country when in danger, are
of higher obligation. To lose our country
by a scrupulous adherence to written law
would be to lose the law itself, with life,
liberty, property, and all those who are
enjoying them with us; thus absurdly
sacrificing the end to the means."
--Thomas Jefferson
