Dear TI, dear forum,
I am polanning an application using the ADS5400 converter. In articles I read the chip was announced to be in production during december '09.According to distributors, the production was delayed until the end of february '10.Yesterday I got the information, that there's another delay and that one can't estimate when the production will start.
Is this really true? Why is there a delay? Certain functions of the chip not working?
Another very important question is: can the chip be imported to germay or might there be problems due to ITAR or sth. like that?
I would be pleased to get some information on this topics because during the last two months I didn't really get useful imformation by phone from the TI support.
Regards and thanks in advance
The ADS5400 production has moved out as we have waited on another lot to arrive from our FAB. We recently received units and are testing them now. We were hoping to release before the end of the year, but the units for supporting production release at that time had the VCM pin stuck in a test mode, invalidating this material for production release.
If devices are required immediately we can sell the devices with the VCM mode problem under waiver. If a system using the ADS5400 AC-couples the input signal to the converter the VCM issue will not be observed and the parts will perform to the level of the upcoming released silicon.
The ADS5400 is governed by the ITAR agreement. The ITAR agreement affects this part in that it limits the countries that the device can be exported to, in particular China, Russia, North Korea, Iran, etc. TI can ship devices like the ADS5400 to Germany without a problem.
Below are the allowed speed-resolution combinations for high speed ADC export. All others are controlled (as of 2/25/10):
8/9-bit – up to 500MSPS
10/11-bit – up to 200MSPS
12-bit – up to 105MSPS
13-14-bit – up to 10MSPS
>14-bit – up to 2.5MSPS
oh this is bad news. Just yesterday I heard that the production would start during the End of March.
Since I would use the ADC in AC-coupled mode I could waive this pin. How can I order Parts with the "non-working" VCM pin? I think if I would order the ADS5400 in the "common" way, I oculd not get it because any distributor would tell me, that It's not released yet.
Thanks and Regards,
I may have been a bit unclear in my response earlier. When I mentioned 'We were hoping to release before the end of the year' this was in reference to the VCM problem material that was to support production at the end of 2009.
The material we just received from FAB is being tested now. Should it be good material as we expect then we will be able to go into production by the end of this month, with the material being tested now being orderable at the time the device goes active (in production).
Since you are AC-coupling the inputs to the ADS5400 you can purchase the previously mentioned parts with the VCM in the wrong mode under waiver or wait for the production units. TI can support you with devices in either manner.
Thanks and Regards,
