ADC1158 Clock generation

Other Parts Discussed in Thread: ADS1158

Greetings to everybody.

I'm trying to use an ADC1158, but it is just not generating clock signal, I'm using the cristal and conetions suggested in user manual but no clock signal is obtained.

Someone who had worked with this DAC can tell me any clue to start using it?

Thank you

    Hi Alejandro,

    Welcome to the TI E2E forums!
    Sorry for the response delay. The correct device name is "ADS1158", because of the typo the question didn't make it into my inbox.

    What crystal part # are you using?

    Often times a crystal will not start because of too much load capacitance, either because of the passive components or because of layout.
    Do you have schematic of your circuit that you can share?

    Best Regards,
    Chris

    Hi Chris,

    Thank you for answer.

    Sorry for the mistake in the reference.

    I'm using a generic 32.7 KHz crystal, not a brand one. This is the conection I made:

    There was not any clock signal in out pin.

    I also tried using external clock, but did'nt work. What is the work frecuency range of this IC?

    Thank you in advance for your help
