Description
Output from the oscillator amplifier.
Ground: 0 V reference.
Analog Ground: 0 V reference. This should nominally be the same voltage
as VSS, but should be isolated to minimize noise and error.
PLL Analog Ground: 0 V reference. This should nominally be the same
voltage as VSS, but should be isolated to minimize noise and error.
1.8 V Core Power Supply: This is the power supply voltage for internal
circuitry.
Analog 1.8 V Core Power Supply: This is the power supply voltage for
internal circuitry. This should be nominally the same voltage as V18 but should
be isolated to minimize noise and error.
3.3 V Pad Power Supply: This is the power supply voltage for the I/O ports.
Analog 3.3 V Pad Power Supply: This should be nominally the same
voltage as V3 but should be isolated to minimize noise and error.
