Searching Clock Generator

Other Parts Discussed in Thread: LMK04906, LMK03200

Hi,

I'm searching the clock generator.

Input is 80MHz from oscilator and I want to generate output 26.67MHz x 5ch.
And output 26.67MHz need to be in-phase against Input 80MHz.
Are there any clock generator which can realize this generation?

best regards,
g.f.

    Hello,

    Devices which have 0-delay feature and can accept your input/output frequencies include: LMK03200 and LMK04906 among others.

    You can do simulations using Clock Architect (ti.com/clockarchitect) by using 80 MHz for input and 26+2/3 for output. Set the filter to LMK04906 to use LMK04906.

    Please note that LMK04906 is a dual loop device, but can be used for dual loop, single loop (your use case), or distribution. See figure 6 on page 5 of revD datasheet for illustration of your use case.

    Hi Timothy,

    Thank you for the reply and I'm sorry for the delay.
    I also need output 80MHz(LVCMOS) and it seem LMK04906 will fit to our spec.
    Thank you so much.

    best regards,
