Part Number: DLPC910
Other Parts Discussed in Thread: DLPC410


in the DLPC910 datasheet @ pin DLPC_DONE Revision D (September 2020) (page12) it states to add 4.7k P.U to 3.3V......but, in sample design this net has a 330 ohm p.u to 3.3V

which is correct to follow? and why is there a mismatch?

thank you!

  • adding to my question. the 330 ohm p.u appears to be from Xilinx UG191 document page 39. question is thus, why Xilinx asks for 330 ohm (and in sample design) while at TI datasheet a 4.7K is asked.

  • Hello Moshe,

    I will need to consult with one of our board guys on this.  I can look to see what is actually on one of the test boards we built which I have in the lab.


  • Hello again Moshe,

    I spoke with our board folks on this one and we have determined that the data sheet is not correct on this one.  The design was originally brought over from the DLPC410 and on that system it is connected to 4.7k Ohm pullup to 2.5 V.  

    The reference design shows 330 Ohm which is correct.  We will set it to be corrected in the next revision of the data sheet.
