LMK00306: minimum input frequency

Part Number: LMK00306

Hi team,

I wonder the minimum input frequency for CLKin0/0* and CLKin1/1*. As per the DS, it will be all the way down to DC. But could you help me to understand what 'DC' exactly means?

Having said that if CLKin0 is 0.2-V and CLKin0* is 1-V in DC, then CLKout would be VCCO*(1-0.2) V. Is my understanding is correct?

    Hi Ella,

    CLKin supports DC coupling, if you put a static voltage to the CLKin pins, the output state (H or L) is deterministic, see Table 3 for details.

    If the voltage at CLKin0* pin is higher than CLKin0 pin, the output is L.
