11 Power Supply Recommendations

CDCM7005 has a simple power scheme. Two power supplies are needed general VCC and analog AVCC. Both supplies should have the same voltage, with individual beads to isolate them. No special power sequencing is needed. A separate supply VCC_CP is used for the charge pump. This supply should match the VCO/VCXO supply but not to exceed the maximum recommended operating voltage of AVCC/VCC.

As PD pin is active low, It is recommended to ramp up the PD with the same time as VCC and AVCC or later. The ramp up rate of the PD should not be faster than the ramp up rate of VCC and AVCC.
