[LMK03002] Registor R0 question, output clock registers

Other Parts Discussed in Thread: LMK03002

Hi Team!

I had a few questions regarding the LMK03002.

On the datasheet, it states that bit 31 is the RESET bit in register R0. Is this the only thing that is present in register 0?

Also, on page 15, section 2.3. It states that "Registers R4 through R7 control the four clock outputs. Register R3 controls CLKout0, Register R4 controls CLKout1, and so on." Is this a mistake? Should the correct statement say the following "Registers R4 through R7 control the four clock outputs. Register R4 controls CLKout0, Register R5 controls CLKout1..." ?

Thank you for all your support!

Ben

    Hello Benjamin,

    RESET bit is the only bit in register R0.  It should be programmed as per datasheet section 2.2 LMK03002/LMK03002C Register Map on page 13 (pdf page 14).

    As for the R4 to R7, you are correct, we mean to start the number at R4, not R3 for the other clock outs.  Thanks for pointing this out.
