3.6 MORE THAN EIGHT OUTPUTS WITH AN LMK01000
FAMILY DEVICE
The LMK01000 family device can be used in conjunction with
a LMK02000, LMK03000, LMK04000, or even another
LMK01000 device in order to produce more than 8 outputs.
When doing this, attention needs to be given to how the fre-
quencies are assigned for each output to eliminate synchro-
nization issues. Refer to AN-1864 for more details.

3.7 GLOBAL DELAY THROUGH AN LMK01000 FAMILY
DEVICE
The delay from CLKin to CLKout is determinsic, but can vary
based on the engaged delays and divides as discussed in
Section 2.3.2 for the CLKoutX_MUX bit. In addition, there can
be variations based on voltage, temperature, and frequency.
AN-1864 discusses this global delay in more detail.
