Description
Connecting a resistor between this pin and ground sets the maximum charge pump output current. The

= 5 mA.
Charge Pump Output. When enabled, this provides ±I
CP
to the external loop filter, which in turn, drives the
external VCO.
Charge Pump Ground. This is the ground return path for the charge pump.
Analog Ground. This is the ground return path of the prescaler.
Complementary Input to the RF Prescaler. Decouple this point to the ground plane with a small bypass
capacitor, typically 100 pF.
Input to the RF Prescaler. This small-signal input is normally ac-coupled from the VCO.
Positive Power Supply for the RF Section. Decoupling capacitors to the digital ground plane should be
placed as close as possible to this pin. AV
DD
has a value of 3 V ± 10%. AV
DD
must have the same voltage as
DV
DD
.
Reference Input. This is a CMOS input with a nominal threshold of V
DD
/2 and an equivalent input resistance
of 100 kΩ. This input can be driven from a TTL or CMOS crystal oscillator, or it can be ac-coupled.
Digital Ground.
Chip Enable. A logic low on this pin powers down the device and puts the charge pump output into three-
state mode.
Serial Clock Input. This serial clock is used to clock in the serial data to the registers. The data is latched
into the shift register on the CLK rising edge. This input is a high impedance CMOS input.
Serial Data Input. The serial data is loaded MSB first with the three LSBs serving as the control bits. This
input is a high impedance CMOS input.
Load Enable, CMOS Input. When LE is high, the data stored in the shift registers is loaded into one of the
five latches. The control bits are used to select the latch.
Multiplexer Output. This multiplexer output allows either the RF lock detect, the scaled RF, or the scaled
reference frequency to be accessed externally.
Positive Power Supply for the Digital Section. Decoupling capacitors to the digital ground plane should be
placed as close as possible to this pin. DV
DD
has a value of 3 V ± 10%. DV
DD
must have the same voltage as
AV
DD
.
Charge Pump Power Supply. This should be greater than or equal to V
DD
. In systems where V
DD
is 3 V, it can
be set to 5.5 V and used to drive a VCO with a tuning range of up to 5.5 V.
