Si5356A
3.12. Power Supply Considerations
The Si5356 has two core supply voltage pins (V_DD) and
four clock output bank supply voltage pins (V_DDOA–
V_DDOD), enabling the device to be used in mixed supply
applications. The Si5356 does not require ferrite beads
for power supply filtering. The device has extensive on-
chip power supply regulation to minimize the impact of
power supply noise on output jitter. Figure 10 is a curve
of additive phase jitter with power supply noise. Note
that even when a significant amount of noise is applied
to the device power supply, additive phase jitter is still
very small.
