• ADN2812 CDR

    === ADN2812 CDR ===

    The LOL (loss of lock) of ADN2812 is asserted around every 200ms for short  period in our system.

    The datasheet shows it will return frequency acquisition mode when frequency difference between VCO & incoming data over 1000 ppm. The…

  • RE: Questions for your ADN2812

    Dear Kaos,

    Yes, an external reference clock can help ADN2812 locking to an input data signal after you have set ADN2812 in "Lock to Reference" mode.

    To do this, you need to write CTRLA[0] = 1.

    In this LTR mode, the ADN2812 locks onto a…

  • What are the finer points of using the ADN2812 to support FDDI data?

    I'm trying to use the ADN2812 to recover an FDDI stream.  I’ve been following the reference design (AN-657) as well as AN-746 “Supporting FDDI with the ADN2812."  I have the ADN2812 in lock to refclock mode and as long as the FDDI data is sufficiently…

  • which register we can read to know the status of HD

    We want to use disable and enable HD(Harmonic Detector) to avoid the abnormal
    frame question.
    And you sent to me some datasheet, we know how to disable and enable HD through
    configure the registers,
    But now, we want to know whether…

  • ADN2816 Evaluation Board Documentation

    Could you please send me the documentation the th ADN2816 EVAL Board?

     

    All the ADN281x CDR product shares the same ADN2812 EVB, with special BOM
    assembly instruction.
    Please find the attached ADN2812 EVB application note and the ADN2816…
  • RE: ADN2913

    Dear HNL,

    Sorry for my typo, it should be 1.3MHz instead of 1.3kHz.

    Did you lock on to an input clock signal or a burst mode PRBS type of modulated data signals?

    Both ADN2812 and ADN2913 supports continuous mode, PRBS type, NRZ encoded data signals…

  • RE: If ADN4612 can both support 1.25G 2.5G and 10G ?

    Sorry for the delay.  Evaluation board materials have been sent offline.

    We recommend the ADN2817  or ADN2818 as "recommended/preferred" instead of ADN2812.  ADN2817/8 are newer products.
