GNDCP

Main frac-N charge pump

ground.

VCCCP

Main frac-N charge pump VCC.

It is decoupled to GNDCP at

the pin of the IC.

MLPF

Main frac-N loop filter (Charge

Pump). The filter is referenced

to VCC.

GNDPRE

Prescaler ground.

VCCPRE

Prescaler VCC. The pin of the

IC is bypassed to GNDPRE.

VCCVCO

VCCVCO is decoupled to

GNDVCO at the pin of the IC.

Extreme caution should be

used when decoupling/routing

to this pin.

GNDVCO

VCO ground.

GNDMOD

Modulation DAC ground.

VCCMOD

Modulation DAC VCC. The pin

of the IC is bypassed to

GNDMOD.

GNDMIX

Mixer ground.

VCCMIX

Mixer VCC. The pin of the IC is

bypassed to GNDMIX.
