    Hi Stan,

    I told you on the last post that your SCLK has too much ringing and over/undershoot.  These look better, but its still pretty noisy.

    Hi Stan,

    You had this working at one point.  Can you please provide a complete schematic and layout of your project?  We want to help you but you are not providing enough detail to debug your setup.

    Hello Tom, I have update you the schematic and numerous waveforms in the previous question threads and you have deliberate close these thread without resolving my problem, why are you dodgeing these problem, this is very unbecoming of you, if you cannot please allow other TI member to advise us, we cannot wait forever for you, we are a revenue generating organization. It has been months since we contact you and TI. Our patience is wearing thin, our team is contemplating ditching TI!

    I enclose again the schematic for your reference...Please help to resolve this, anyone in TI….

    Hi Stan,

    Every interaction gets 'closed', that does not mean we abandon you.  It just level sets the conversation.  You had the TLV1570 working at one point, so please go back to where you were at that point in time.  From what you have told me, you have a breadboard with fly wires and its not working out for you.  Have you created a proper printed circuit board or not?  You have provided a white board schematic and signal traces for the SCLK that ring excessively.

    The DAC circuit is implemented on a bread board, and its working fine... i would need time if implemented on PCB which our hardware guys would not recommend cause we are designing the which custom board. Could anyone in TI please help .....

    Hi Stan,

    I can have my associates ask you the same questions if you think that will help.  Your ringing SCLK is giving you issues.  If that is because of fly wires and breadboard hookups there is not much we can do to help you.  I believe the issues you are having is due to your hardware and not directly related to the TLV1570 itself.
