Clock Synthesizer Suggestion

Other Parts Discussed in Thread: LMK05318B, LMK03328, CDCE6214, LMK3H0102

Kindly suggest Clock Synthesizer, where the following outputs shall be configured 125MHz, 100MHz, 156.25MHz (LVDS), 300MHz and 25MHz(LVCMOS). It shall be hard-coded and each outputs shall have dedicated enable/disable future as well. 25MHz output frequency is not mandatory

    Manikandan,

    The team is out of office for the US holiday, please expect a response by tomorrow.

    Thanks,

    Manikandan,

    Is the 300MHz clock LVDS, or LVCMOS? The below recommendations assume LVDS, as we do not have any devices that support LVCMOS at 300MHz.

    LMK05318B and LMK03328 can generate all of these clocks, but not with the dedicated individual output enable. Only global output enable is supported.

    LMK3H0102 + CDCE6214 can support this request with individual output enable.

    If you can clarify the formats for the clocks, and let us know of any jitter requirements, I can provide more specifics for this configuration.

    Thanks,

    Kadeem
