DESCRIPTION
DESCRIPTION
-
Input power supply voltage (2.7V -5.5V), for RF
analogue/digital circuits. VCC1 must equal VCC2.
-
Power supply for charge pump. Must be ≥ VCC.
O
Internal charge pump output.
-
Ground for digital circuitry
-
RF prescaler input. Small signal input from VCO.
-
RF prescaler complementary input.
Ground for RF analogue circuitry.
-
Oscillator input.
-
Digital ground.
