DAC38RF82: DACCLKSE Electrical Specifications

Part Number: DAC38RF82

hello,

Regarding the DACCLKSE input pin:

1. How does the input stage, electrically, look like for this signal?

2. What is the Vcom, Vi(pp) and/or any other voltage specification for this pin's signal?

thanks

Gil

  • Gil,

    We are looking into this.

    I am still waiting on a response from the design team.

    Hi Jim,

    Any progress?

    I found this post: https://e2e.ti.com/support/data_converters/high_speed_data_converters/f/68/t/651655.

    How applicable is it to my question for the DAC38RF82?

    thanks

    hello Jim,

    Still no answer from the design team?

    Can I use the post above (as I wrote)?

    I would still like to have additional data besides the 1Vpp.

    thanks

    Gil

    Gil,

    Most of our staff is on holiday, thus the reason for no response. What exactly do you mean by using the post above (as I wrote)? If this was the 1Vp-p spec, I would say yes.

    Regards,

    Jim

    Jim,

    See the post above my last post.

    It asks if I can use your reply for a post that has some relevance to mine:

    I found this post: https://e2e.ti.com/support/data_converters/high_speed_data_converters/f/68/t/651655.
    How applicable is it to my question for the DAC38RF82?


    So, yes. I wanted to know if the 1Vpp is also applicable in my case.

    And I also asked if more electrical data for DACCLKSE can be supplied.

    thanks

    hello Jim,

    Any reply to my original post on this thread?

    Thank you

    Gil,

    The CM for this input is 0.5V. What min and max values does your design provide to this input? I am still working with the design group on obtaining these values.

    Regards,

    Jim 

  • In reply to jim s:

    Jim,

    So, after the DC block capacitor, the device gives this input, internally, a CM of 0.5V.
    Correct?

    I need to know what is the minimum and maximum Vi(pp) for this pin (around the 0.5V).

    This input is externally driven by a signal generator (external to the board).

    thanks
    Gil
