Hi Lisa,

We urge customers to use the LMK05318B as that is the latest silicon. The LMK05318B (even the LMK05318, though not recommended) can meet those requirements.

It is recommended to route to place identical frequencies on adjacent outputs, such as moving 100 MHz on OUT3 to 100 MHz on OUT6.

Regards,

Jennifer

Hi Lisa,

You may find the key summary here:

The fixes are essentially to allow low frequency inputs and more APLLx divider flexibility by adding a programmable denominator.
