Need a ADI recommended Fractional N PLL

Hello,

My customer wants to use ADI PLL devices, so they request your recommeded  PLL device adapting below conditions.

Please refer below conditions and let me know your opinions.

Case 1:

        1. Reference Frequency: 153.6MHz

        2. Reference Frequency: 10MHz

        3. Output Clock Frequency: 322.265625MHz

   

         If you can recommend, both reference Frequencies are supported.

         If you can't, 153.6MHz is more important than 10MHz.

Would you recommend ADI PLL adapting above conditions?

Case 2:

        1. Reference Frequency:  322.265625MHz

        2. Output Clock Frequency: 153.6MHz

        

        If 322.265625MHz is too high, they can use divided- N (integer) frequency of this.

    

  Would you recommend ADI PLL adapting above conditions?    

Please advise me.

Regards,

Se-woong

  • Dear Neilw,

    Thank you for your kind explanation.

    Anyway, about choosing a fractional N PLL device, how about using below devices for case #1 & 2 in my previous request?

    I can get a list of below devices from ADSimPLL with Single Output/Fractional-N, 322.265625MHz Output/, 25KHz PD Freq., 153.6MHz Ref. Freq.

    Please refer a list of  below devices and let me know your opinions.

        1. HMC703
        2. HMC704
        3. HMC829
        4. HMC830
        5. HMC832
        6. HMC833
        7. HMC834
        8. HMC835
        9. HMC7759
