oscillators of DPLL #1 and DPLL #2 to have
maximum tolerances of ±32ppm and ±50ppm
respectively.
However, if DPLL #1 and DPLL #2 are daisy-chained
as shown in Figures 9 and 10, the output clock
tolerance of DPLL #1 will be equal to that of the
DPLL #2 oscillator when DPLL #2 is free-running. In
this case, the oscillator tolerance of DPLL #1 has no
impact on its output clock tolerance. For this reason,

it is recommended to use a ±32 ppm oscillator for
DPLL #2 and a ±100 ppm oscillator for DPLL #1.
Differences between MT8941 and MT8940
The MT8941 and MT8940 are pin and mode
compatible for most applications. However, the user
should take note of the following differences between
the two parts.
