LMK5B12204: ZDM fucntion implemention

Part Number: LMK5B12204
Other Parts Discussed in Thread: LMK05318B

Hello,

I would like you to confirm about below.

* I would like to align phase between input clock and output clock by using LMK5B12204.
According to datasheet, there is following description. but there is no information about register setting and internal function block about this.

* Output will have deterministic input-to-output phase relationship if Zero-Delay Mode (ZDM) SYNC is enabled.
(P56, Figure 9-33, PLL start-up sequence)

Is it possible to realize ZDM function by using this device ?

BR,

    Hello BR,

    Yes, the ZDM feature can be used to align the phase between input and output clock.

    Unfortunately, the LMK5B12204 does not support ZDM mode.

    The 8 channel version of the LMK5B12204 does support ZDM between the input and OUT7. The 8 channel version is the LMK05318B.

    Regards,
