LMK1D1216: Can ONE input signal (IN0) fan out to ALL 16 Output Channel pairs?

Part Number: LMK1D1216
Other Parts Discussed in Thread: LMK1D2108

Hi, I am reading the documentation here and here for this board and I can't tell whether one input signal (IN0) is capable of fanning-out to all 16 output channels or if IN0 is restricted to OUT0 through OUT7 only? I can't make sense of the documentation.

Our design effort was planning on having one input signal fan-out to all 16 output channels.

Please advise - thank you!

Thomas

    Yes, you can insert one input signal (e.g. to IN0) and fan it out to all 16 outputs of LMK1D1216. LMK1D1216 routes either IN0 or IN1 to all of OUT0 through OUT15, depending on the state of the IN_SEL pin.

    There is another device with the same pinout, LMK1D2108, which is similar to the LMK1D1216 except that it splits the output banks as a dual 1:8 buffer. In LMK1D2108, IN0 is restricted to OUT0 through OUT7, and IN1 is restricted to OUT8 through OUT15.

    LMK1D1216 and LMK1D2108 share the same package, pinout, and many design characteristics, so much of the documentation is common between devices - this may give rise to some ambiguity. If there's specific language in the documentation that's confusing or contradictory, or something you feel is absent that should be explicitly present, let us know and we'll put it in the queue for the next documentation revision.
