TAS6422Q1EVM: Seeking documentation PDFs for eval. kit....

Part Number: TAS6422Q1EVM
Other Parts Discussed in Thread: CC2650

Hi all,

I have been through the ringer on trying to get documentation on the evaluation modules I ordered through Mouser.

Eval. kits are: TAS6422Q1EVM and TAS6424Q1EVM , ICs are: TAS6422Q1 and TAS6424Q1


I will be using both parts in a 6 channel multi-phase array for a navigation aid in the Gulf oil fields (fog-horn alert and storm warning/tsunami

warning) device. I need the full documentation on the modules, I already have purchased parts from Mouser of both ICs and the TAS6422Q1EVM

to get prototyping. Please advance the documentation on the EVM  modules so I can get a thumb nail reference design going as soon as possible.

For some strange reason I fill out the info. on that form but get a "rejected" a day or two later and no reason or missing piece of info. is asked for.

Seems strange that TI would make it so hard to get documentation on something I can order from Mouser so easily.  The documentation should

have came with the modules or at least a "key" to use to access them on TI's web site if they are "family secrets".

This is the form link, I am in Colorado, don't know why there is an export form needed any ways?

"www.ti.com/licreg/docs/swlicexportcontrol.tsp?form_id=171739&prod_no=TAS6422Q1EVM&ref_url=HPAAudioAIP"

I've filled this out and submitted it several times, from two different browsers and it gets bounced back "rejected" or I get this email:

"Hello,

 Unfortunately, we are not able to verify your information. Please contact your local TI Sales office for more information.

 Best Regards,

   Audio Software Team  ,    Texas Instruments"

With no explanation on what they are trying to verify or what has not verified for them, it's just an email address and my TI login

as well as the part numbers, quantiles and dates????

Can somebody in "Audio Amplifiers Department" please find out why or help me or point me to the department of person

in charge of this so I can move on?   I don't want to have to "move on" to another vendor due to such a silly problem.

I easily submitted and received the CC2650 Cortex-M3 CPU info. and doc. packages that I needed already, what gives?

I have the data sheets/PDFs on the actual amplifier ICs already, just need sufferance design and EVM documentation!

Thanks,

Marc Y.

 

 

 

  • Hello all, 

    I've got the exact same problem. Have no idea why. TI, please explain, what is going on here, and why the datasheet for TAS642xEVM is so secret??

  • Hello Marc! I am sorry about that as these requests pass through TI's export control department who has a protocol that they walk through to give approval. If the email address you noted in your my.ti.com account is the current address I can have the approval sent your way? Just please let me know. Thanks, Jeff
  • Hi Jeff,
    Thanks for the attention. Yes that is the email to use and I did get some access to things I don't need. I do not plan to use that PurePath
    stuff at all. I did not see anything on the TAS6422Q1EVM kit (other than a couple page revisions/notes), still no access to what ever doc. I would need to understand this module and be able to use the marked pins on it to connect my I2S controller and use a scope to probe around on the board to see what it's doing with large loads and power supply swings. There has to be a manual/schematic/bom on this board as it is your reference design for the IC itself???? Can you connect me up to that PDF file? I wonder of Mouser will take it back at this point, although I really like those two parts for what we are designing.
    Thanks Marc
  • Hello Marc! Those two documents have been sent over to your email. thanks, Jeff
  • Thanks Jeff, finally I scored the correct doc. package for the reference design  I was seeking, yeah!

    These Class-D amp's TI offers are the best solution for us being we can generate I2S waveforms

    and send them right to the ampl. IC with no analog path.  Throw I2C controls in there and wide

    power supply variation handling (closed-loop) we are well within our spec. for the coast guard

    battery powered navigation aids products requirements.

    Thanks for nailing this down for us!

    MY

  • My pleasure! Thanks, Jeff
