• AD9558 Jitter Performance


    I have two questions about AD9558.

    • Is there any tool to estimate jitter performance of AD9558 with custom configuration?
    • If no, could you provide an estimation of clock output rms jitter performance with following configuration?
      • System clock (49…

    Can I use EVAL-AD9558 to programming AD9558 on-chip EEPROM? Is there any user guide for EVAL-AD9558 borad?


    1, click EEPROM button;

    2, check EEPROM Write Enable;

    3, click Write Sequence to EEPROM

    Follow the above operation sequence, I can not program…

    Can I use AD9558 or AD9558 with gapped clock for asynchronous demapping SDH from OTN?

  • RE: AD5933 external clock signal


    As stated on UG-364, for a 16MHz crystal to generate your desired MCLK frequency an external clock divider should be used. To achieve a 25kHz MCLK, the 16MHz crystal should be divided by 640 which can be done using AD9558 or AD9959 that is controlled…

  • RE: frequency synthetizer

    Hello Zanzibar,

    We have four solutions:

    1. The AD9578

    2. The AD9558, AD9559, and AD9554-1. This are DPLL based jitter cleaning PLLs but also work as synthesizers. You might consider these if you want to ultimately have your clocks locked to a reference…

  • RE: AD9958扫频问题

    AD9558支持向上、向下线性扫描。如数据手册的36图(Linear Sweep Parameters)。

    请问你的寄存器REG0x07, REG0x08, REG0x09,CFR REG0x3的内容是多少,另外Profile PIN是否正确切换?

  • RE: Three outputs from External Crystal

    There are a few options to consider:

    - The AD9577 is a fully configurable part which can use a XTAL reference and has four outputs, but the minimum output frequency is 11.2 MHz.

    - The AD9553 is a fully configurable part  which can use a XTAL reference…
