output configuration A
Output configuration A is valid when any output configured as a 1x frequency output in Table 1 is fed back to
FBIN. The input frequency range for CLKIN is 50 MHz to 100 MHz when using output configuration A. Outputs
configured as 1/2x outputs operate at one-half the CLKIN frequency, while outputs configured as 1x outputs
operate at the same frequency as CLKIN.

output configuration B
Output configuration B is valid when any output configured as a 1x frequency output in Table 2 is fed back to
FBIN. The input frequency range for CLKIN is 25 MHz to 50 MHz when using output configuration B. Outputs
configured as 1x outputs operate at the CLKIN frequency, while outputs configured as 2x outputs operate at
double the frequency of CLKIN.
