ADIS16223 Rev0 Data sheet typos?

Are these typos? The Rev 0 Data sheet for ADIS16223 as downloaded from AD website has a couple of important typos.

Page 14 of 20

Alarm Indicator states "Set GLOB_CMD[4]=1 (DIN = 0xBF10)"

The DIN should be 0xBE10 not 0xBF10 ?


Page 15 of 20

Self-Test states "Set GLOB_CMD[2] = 1 (DIN = 0xBE02)"

The DIN should be 0xBE04 not 0xBE02 ?


I have drawn up a table based on Table 27 but with the addition of the DIN commands as I understand them.

Please can you check the above observations and the table below for accuracy / errors.

Are the observations above due to typos or have I misunderstood the GLOB_CMD[x] commands?

  • Thank you for posting this. I haven't tested this product in a while, so I will need to get my setup together and try this out.  Might take a few days to get back to you on this one. Based on everything I see right now, 0xBE02 should power the device down and 0xBE04 should be self-test.  We will figure this out. Thank you!

  • Just wanted to offer a quick update. I was unable to verify this on my evaluation tools, so I will need to find another way to test this. I might need a few more days to close this out.  Thank you!

  • We are still working on being able to test the power-down on the evaluation tools, but I did speak with the Product Test Engineer for this product and he confirmed that Power-down is part of our automated testing of these devices. He reviewed his test procedure and confirmed that GLOB_CMD[1] actually does initiate the Power down.  As we were talking, one idea came up, which might help you.  The GLOB_CMD is unique in that you only need to write to one byte at a time.  So, if you send DIN = 0xBE02, the device should go into the power down mode. However, if you send 0xBF00 afterwards, it will wake the device up. Could that be what is happening in your setup?

  • Just closing the loop on this. Sorry about the delay.  We have been able to confirm that our automated test for the ADIS16223 runs both Self-test and Power down functions.  Our Product Test Engineer (PTE) has verified that the coding in the table that I posted, is correct.  In our evaluation software, we found that it was waking the device up, by sending the 0xBF00 command, as I had described in my previous post.  Could that be what is happening in your attempt to observe a power down?
