LMK00105: Input Circuit

Part Number: LMK00105

Hi team,

Is it possible to feed a 5v LVCMOS input into the subject part? If so what is the appropriate input circuit?

Thanks.

    The input swing needs to be limited to Vi_se max. Use a voltage divider to attenuate the swing and limit the sum of the 2 resistors values to 500 ohms (e.g. 300 ohms series, 200 ohms to ground) to minimize high frequency roll off. Also, make sure the LVCMOS driver has series/source termination to impedance match the PCB trace.
