LMK04828B - Operating Mode

Hello,

I have a question about LMK04828B.

Can this device operate by Single PLL Mode, 0-delay Single PLL Mode and Distribution Mode?

 

Regards,

Hiroshi Katsunaga

  • Yes.

    The setup would be similar to...

    • Single PLL mode = dual loop mode (but with PLL1 powered down), and
    • Single PLL mode, 0-delay = Dual loop cascaded 0-delay (but with PLL1 powered down)
    • Distribution mode can use CLKin1 as external VCO mode, but with PLL1 and PLL2 related functions powered down.

    See register 0x140 and 0x173 for some more power down bits, like PLL1_PD.

    Instead of using CLKin, OSCin would be used for an input.  Do you require more than one input (OSCin) in your single loop modes?

  • Timothy-san,

    Thank you for your fast reply.

    My view became clear.

     

    Your Question : Do you require more than one input (OSCin) in your single loop modes?

    →No, I don't. My customer is satisfied with one input now.
