Description
DC Power Supply for analog circuitry.
The pins are not connected internally; however, all data shown herein was measured
with these pins connected to RF/DC ground externally.
Power Supply for charge pump analog section
Charge Pump Output
Power Supply for the charge pump digital section
Reference Supply
Reference Oscillator Input
DC Power Supply for Digital (CMOS) Circuitry
Chip Enable. Connect to logic high for normal operation.
VCO Varactor. Tuning Port Input.
VCO Analog Supply 2
VCO Analog Supply 1
VCO Divide by 2 RF Positive Output
VCO Divide by 2 RF Negative Output
PLL Serial Port Enable (CMOS) Logic Input
PLL Serial Port Data (CMOS) Logic Input
PLL Serial Port Clock (CMOS) Logic Input
Lock Detect, or Serial Data, or General Purpose (CMOS) Logic Output (GPO)
DC Power Supply for Analog Circuitry
DC Power Supply for Analog Prescaler
DC Power Supply for Phase Detector
External bypass decoupling for precision bias circuits.
Note: 1.920V ±20mV reference voltage (BIAS) is generated internally and cannot
drive an external load. Must be measured with 10GΩ meter such as Agilent 34410A,
normal 10MΩ DVM will read erroneously.
