Note that RCA DTA-800 comes in two very different versions:
RCA DTA-800B uses Broadcom's new BCM3543 "super-chip"
which has an internal ATSC Decoder function:http://www.broadcom.com./press/relea...45&source=home
RCA DTA-800A uses Zoran SupraHD 640 "super-chip" with a
separate Cascade 220 ATSC Decoder chip (an older design):http://www.zoran.com/Zoran-Corporati...che=rca+dta800
Apex DT1001 uses the latest Zoran SupraHD 741,
with internal ATSC Decoder function.
But we still don't know whether 5th or 6th Generation LG chip
is used in LG Insignia and LG-Zenith boxes....or maybe something else....
until someone checks the part numbers:http://english.chosun.com/w21data/ht...612280032.html
The smaller 6th gen is on the left and 5th gen LGDT3303 on the right....
and 4th gen LGDT3302 was in LST-4200A HD-STB.
Sansonic FT300A and FT300RT use Auvitek AU8515 ATSC Decoder chip with
MicroTuner MT2131 Double Conversion RF Mixer/IF chip:http://www.microtune.com/products/pdf/mt2131_11.pdf
Nearly all HDTV/HD-STBs are Single Conversion....it is not yet sorted out
how the advantages & disadvantages of each are somehow "better" overall....
Auvitek's "6th Generation" had longest equalizer length ever tested by CRC:http://www.tvtechnology.com/pages/s.0115/t.10652.htmlhttp://www.tvtechnology.com/pages/s.0115/t.10454.html

FYI: More info re earlier CRC Tests (Samsung outperformed LG 5th Gen):http://www.avsforum.com/avs-vb/showt...=basic+english
No one ever made a "Gemini" ATSC Decoder chip...but Samsung DTB-H260F
actually uses AMD-ATI Xillion 240H chip with an Alps Tuner NIM.
PrimeDTV PHD-200 & PHD-205 also use AMD-ATI Xillion 240H w Alps NIM.
An AMD-ATI report re A/74 Field Ensemble test results:http://gullfoss2.fcc.gov/prod/ecfs/r...ent=6517693762
Two "best" chips are their own products--no doubt Theater (T312, T314)
and/or Xillion chips.
FCC OET comparison test of various HD-STBs & HDTVs (Sec 6 Field Ensembles):http://gullfoss2.fcc.gov/prod/ecfs/r...ent=6517693762
No names, but one low performance HD-STB has Smart Antenna control...
hence is my Sylvania 6900DTE (with 3rd Gen AMD-ATI NXT2004).
There were two groups: high performance HDTVs and low performance HDTVs/HD-STBs.
My guess is the high performance units contained Theater/Xillion and/or LG 5th Gen chips.
And the "best" low performance HD-STB was probably the LG LST-4200A
(highly rated at the time)....with a dearth of 5th Gen HD-STBs.
Wish CRC would release these new reports....newer should be better....
Since the LG 5th Gen and Zoran Supra 640 + Cascade 220 chips are older
designs, I'll be avoiding those units (e.g. RCA DTA-800A, the "A" version).
Unless some specific test results magically appear, I'll equally consider
Zoran SupraHD 741, Broadcom BCM3543, Auvitek 8515 and LG 6th Gen....
But I'm only interested in boxes with EIA/CEA-909 Smart Antenna interface.
