Part Number: CDCE913

Hi,

My customer is evaluating CDCE913 and uses not a Xtal but an external clock.

When the external clock stops and restart, PLL of CDCE913 does not lock.

What is recommended workaround for this condition?

Best Regards,
Kuramochi

    Hi Kuramochi,

    Unfortunately I didn't find a soft reset bit or recal bit that recalibrates VCO. Is it possible to toggle the PWDN bit then rewrite all registers?

    Regards,
    Hao
