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 
"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
