Clock Generator recommendation

JH Shin
Guru 10950 points

Hello,

My customer is looking for a clock generation device that can generate a clock like this:

Could you please recommend a suitable clock generation IC?

Thank you.

    Hi JH,

    Could you specify:

    1. Is the output 'Single 100 Hz ~ 10 MHz' exact as the input?

    2. Do you have the specific frequency for this single output? This would help determine if the clock generator would use 2x or 3x PLLs.

    1. Is the output 'Single 100 Hz ~ 10 MHz' exact as the input?

     

    -->  It is a 10 MHz single input (LVCMOS or CMOS)

      

    1. Do you have the specific frequency for this single output? This would help determine if the clock generator would use 2x or 3x PLLs.

      

      --> The fixed frequency of the output is 155.52 MHz and 156.253 MHz. (LVPECL)

     --> The other output frequency is a bypass of the input frequency. (10MHz, LVCMOS or COMOS)

    Hi Haeseung,

    You can use LMK03328 which has 2x PLLs to generate the 2x LVPECL clocks and bypass the LVCMOS/CMOS input clock. Note that only OUT4-7 can bypass the input clock. Hope this helps.
