Hi,
We have recived today an end of life notification for our distributor Digikey (with a final order date of the 17th Aug 2024) for the AD LTC6957 clock buffer.
We are very heavily invested in this component in our end products so the distributor's notification has potential for serious impact on our business and we are looking for AD confirmation of any change in product life cycle status.
Checking the AD product page today the LTC6957 flagged as "recomeneded for new designs"
Can you please confirm if the LTC6957 is indeed still recomended for new designs ?
If so how long does this status indicate supply will be maintained for ?
Is the distributor correct that the device is due to be end of lifed ?
If this is not the correct forum to make life cycle can you please direct us to a point that can help with this query.
Thank you in anticipation.
Nick.
Hi Nick,
Sorry to relay this bad news. The distributor is correct. This was part of one of vendors discontinuing a wafer fab process, that affected several different part numbers.
The PDN (product discontinuation notices) is on the analog.com website also (ADI_PDN_23_0089_Rev_-_Form.pdf (analog.com)). The PDN outlines the last time buy and ship dates. We are working to update our website to state 'Life Time Buy', instead of Recommended for new designs.
Thanks
Chris
Chris hi,
Thankyou for coming back and clarifying the position.
Looking at the linked PDN notice unfortunately the situation looks more serious for us, we also use the LTC6952 which core to our product and which is also listed for EOL.
We originally developed our application / imbedded firmware on the LTC6950 which was then flagged to EOL just as the development was completed. This drove a move the LTC6952 and a lot of effort to change pcbs, reintegrate and verify.
I hope looking at the PDN pdf you kindly linked above that there may be a solution. Both the LTC6947 and LTC6952 have no immediate replacement parts listed. However in the comments entry of the table each seems to have a direct replacement planned at some future point. The listings state:
"ADF6957 will be function, package, and pin compatible with LTC6957"
"ADF6952will be function and package compatible with LTC6952"
There is no information on the AD site currently for these new parts parts. We need a plan in place to manage the withdraw / possible move to the new parts. Would you be able to help me with the following questions.
Can we have confirmation that these new part numbers are fully committed AD product releases ?
It would be immensely helpful to have time frames for the new components becoming available (particularly if a Fab move is involved, this becomes a concern) and access to datasheets to check specifications ?
Thanks,
Nick.
Do you have a local ADI Field Engineer or Salesman, or local distributor that you work with on ADI parts? The information requested is usually handled through those channels. Let me know, if not I can try to figure out if there is someone you can talk with.
I also have this question in regard to the LTC6952 and details around ADF6952.
I think this information would be helpful for the wider ADI community.
Chris hi,
I don't have a field engineering or sales contact, we do most of our work through distributors, if I can take you up on the offer to link me up with someone in ADI that could help here I would be very grateful.
Nick.
Chris hi,
I am not sure if I used the correct reply button below and you may not have seen my follow up message. Thank you for your help so far and offer to link us up with a point that can assist, I understand that the forum is not the appropriate place for these follow up questions.
I am coming under pressure now to make recommendations to the business on how these EOL events should be managed and have been looking at other channels to reach someone in ADI who can help with our questions. If you could assist by pointing us to preferably a contact point or channel to help us that would be very helpful indeed ?
From reply below:

ChrisPearson Hello, I would like to reiterate that I think the ADI community would like to know more about ADF6952, but will also take you up on your offer for field engineer support. I have emailed who I believe to be our sales engineer over the past 2 weeks and haven't heard anything. If you can recommend someone for me to speak to as well, that would be helpful. Thanks!
I apologize sales is not responding and also my delay. I have sent an email internally to figure out how to handle this. Usually such discussions are not done a public forums.
Hi Nick, your email address looks like home email address. Can you have someone with your companies address email ADI sales, or respond to the engineerzone post?
Hi Chris,
Thanks for the help pointing my to the right contact point.
Engineering Zone profile should now be up to date with company mail details.
Just in case there is a problem I will also pm you my contact details.
