Mnemonic Description
1
AVDD
DC Power Supply for Analog Circuitry.
2, 5, 6, 8, 9, 11 to
NC
14, 18 to 22, 24, 26,
34, 37, 38
No Connect. These pins are not connected internally; however, it is recommended to connect these
pins to RF/dc ground externally.
3
VPPCP
Power Supply for Charge Pump Analog Section.
4
CP
Charge Pump Output.
7
VDDLS
Power Supply for the Charge Pump Digital Section.
10
RVDD
Reference Supply.
15
XREFP
Reference Oscillator Input.
16
DVDD
DC Power Supply for Digital (CMOS) Circuitry.
17
CEN
PLL Subsystem Enable. Note that there is no effect on the VCO subsystem. Connect to logic high for
normal operation.
23
VTUNE
VCO Varactor. Tuning port input.
25
VCC2
VCO Analog Supply 2.
27
VCC1
VCO Analog Supply 1.
28
RF_N
RF Negative Output.
29
RF_P
RF Positive Output.
30
SEN
PLL Serial Port Enable (CMOS) Logic Input.
31
SDI
PLL Serial Port Data (CMOS) Logic Input.
32
SCK
PLL Serial Port Clock (CMOS) Logic Input.
33
LD/SDO
Lock Detect, or Serial Data, or General-Purpose (CMOS) Logic Output (GPO).
35
VCCHF
DC Power Supply for Analog Circuitry.
36
VCCPS
DC Power Supply for Analog Prescaler.
39
VCCPD
DC Power Supply for Phase Detector.
40
BIAS
External Bypass Decoupling for Precision Bias Circuits. Note: 1.920 V ± 20 mV reference voltage (BIAS) is
generated internally and cannot drive an external load. It must be measured with a 10 GΩ meter, such
as the Agilent 34410A; a normal 10 MΩ DVM reads erroneously.
EP
Exposed Pad. The exposed pad must be connected to RF/dc ground.
