Hello
Kindly can anyone forward me the BOM and schematic of TMS320DM648.
I have with me the BOM and schematic of TMX320DM648 , i want to compare the
difference btw da two.
Kindly reply asap

You give a device part number [TMS320DM648] and use the terms 'BOM and
schematic' which are board terms.
I assume that you are looking for a BOM and schematic for some
particular board. If so, it would help if you identified the board
vendor [Lyrtech, Spectrum Digital, or ??] and their part number. BTW,
they usually have revision info on their web sites.

TMX Experimental device that is not necessarily representative of the
final device's electrical
specifications.
TMP Final silicon die that conforms to the device's electrical
specifications but has not completed
quality and reliability verification.
TMS Fully-qualified production device.

Adding to Mike's comments, if you want to compare experimental vs. production version
of TMS320DM648, then you want the errata:
http://focus.ti.com/lit/er/sprz263e/sprz263e.pdf
If the current errata (Rev E) doesn't cover TMX, then you may be able to find earlier
versions of the sprz263.pdf file (Rev D, Rev C, etc). But you might have to ask TI,
as they tend to remove old versions of errata as soon as they put up a new one.
Note this comment about TMX:
[TMX indicates] Experimental device that is not necessarily
representative of the final device's electrical specifications

Hello
Yes the board is from Lyrtech. They have actually updated the chip to TMs320Dm648 from TMX320DM648 .
So i am asking , does this upgrading changes the BOM and schematic of the board??
bec i want to compare it my TMX320DM648 lyrtech board.
IF u hve the BOM and schematics of TMS320DM648 lyrtech board kindly forward it to me .
Gud day all
waiting for a reply
Regards
Almira

Lyrtech should be able to tell you whether there is any change to a board with TMX part vs. a board with TMS part.
They may not give you the BOM and schematics though, as I believe they consider their boards as proprietary, as
opposed to something like GNU radio where you can freely download the hardware design material.
Sometimes PCB changes are minor and not easily visible, so one thing you can do is check the PCB very carefully for
markings like 1.1 vs. 1.2, 1.01 vs. 1.02, etc. PCB revision markings are sometimes shown in the silkscreen (typically
white or yellow lettering) and sometimes etched as copper or solder mask on a surface layer. The latter can be hard
to find, you have to look closely.

hola
I am very confused .. bec i hve already bought DM648 board from lyrtech based on tmx320dm648. Lyrtech ppl provided the complete list of BOMs and the schematic along with it. N it is evm so , such information is always provide.
If anyone has purchased Dm648 board from lyrtech , based on tmx320dm648 , they will hve the BOM and schematic too . I f anyone has it kindly share it with me my email address is g...@yahoo.com .
Waiting for a reply
Regards
Almira

If Lyrtech gives out the schematic and BOM for the the board, then just ask Lyrtech these questions:
1) Can you get their latest schematic version?
2) Does the schematic show any difference depending on silicon revision of DM648 device installed on the board? (Of
course, be specific also about TMX vs. TMS part).
It should be easy. Is there something you're not saying? Otherwise I don't understand why you can't get this solved
with Lyrtech with simple e-mail or phone call.

hello
I hve already mailed lyrtech but they r not keen on replying ... still waiting form answer from them ...
So i mailed at da group instead ... if nyone else may have clue about this ... if some1 does plz share the info.
Regards
Almira

Almira,
I suggest a post to one of TI's forums [I think they have one for
DaVinci media processors] at:
http://community.ti.com/forums/
These are monitored by TIers [most of the time]
As I understand your question, the 'real question' is "What is the
difference between the TMX320DM648 and the TMS320DM648 devices?"
And, if there are differences, "What design changes are required to
support them?"
You may also want to mention that you are trying to get info from
LyrTech on the differences between their EVMs that have the
TMX320DM648 and those that have the TMS320DM648.
I will now add some comments about board changes/differences and the
way that you asked your question.
1. I have been involved in several projects that transitioned from TMX
to TMS devices. I have never had to make a board change to go from
TMX to TMS devices.
2. Many engineers do not understand the issues involved in "making a
simple change [from the engineer's view] in the manufacturing process.
Sometimes when a change is known [minor improvement, device changes
that require PCB changes, etc.], it is not implemented immediately for
a variety of reasons. Then, when a mandatory change comes along [like
TMX devices are no longer available], it is implemented and any
"queued up changes" [possibly totally unrelated] are implemented at
the same time.

Suggest to e-mail them again and:
-mention that C6x group members say "this is an easy question
and Lyrtech should be able to answer it promptly"
-attach the whole thread
-Jeff
PS. I might mention that you have been "cutting text" from each reply, which is bad form for group communication.
Therefore, now to make effective use of this thread, you have to manually edit all your messages with this subject
line to reconstruct the complete dialog. You're making things more difficult for yourself -- more difficult to get
help, taking more time to get the answers you need for your project. Not good engineering practice.
