Hi team,

Is there a delay between the enablement of LMK3H2104 via OE pins and clock output from output pins?

I would like to know if there is a delay on other devices;

Yamamoto-san,

For LMK3H2104, the timing for enable and disable based on the OE pin state is given by this table from the Electrical Characteristics table:

Thanks,

Hi Kadeem-san,

Thank you for the clear explanation. Regarding No sync mode, Is it possible to choose 0ns of t_OE by internal register setting?

Best regards,

Yamamoto-san,

No sync mode is the fastest method, but is not configurable between 0ns and 40ns. It is anywhere between the two times. Selecting no sync mode instead of full sync mode is register configurable.

Thanks,

Kadeem
