    Hi Sir,

    Our customer used the Main chip reference code, There are some improvements, But they are hope Jitter under 40ns.

    Could you please share some suggest for me?

  • In reply to Hugo Liu:

    Hi Hugo, 

    Thanks for the update. 

    Can make Fz lower and Fp higher to see if it helps reduce jitter further. 

    I'm not sure if we can make jitter less than 40ns. The impact of jitter is output ripple. As long as output ripple meet spec, it should be fine even jitter is larger than 40ns. 

    Thanks

    Qian
