Description

RSET
Connecting a resistor between this pin and CPGND sets the maximum charge pump output current. The
nominal voltage potential at the RSET pin is 0.66 V. The relationship between ICP and RSET is

where RSET = 5.1 k and ICPMAX = 5 mA.
2
20
CP
Charge Pump Output. When enabled, this provides ±ICP to the external loop filter that, in turn, drives the
external VCO.
3
1
CPGND
Charge Pump Ground. This is the ground return path for the charge pump.
4
2, 3
AGND
Analog Ground. This is the ground return path of the RF input.
5
4
RFINB
Complementary Input to the RF Input. This point must be decoupled to the ground plane with a small
bypass capacitor, typically 100 pF. See Figure 11.
6
5
RFINA
Input to the RF Input. This small signal input is ac-coupled to the external VCO.
7
6, 7
AVDD
Analog Power Supply. This can range from 2.7 V to 3.3 V. Decoupling capacitors to the analog ground
plane should be placed as close as possible to the AVDD pin. AVDD must be the same value as DVDD.
8
REFIN
Reference Input. This is a CMOS input with a nominal threshold of VDD/2 and a dc equivalent input
resistance of 100 k. See Figure 10. This input can be driven from a TTL or CMOS crystal oscillator or it can
be ac-coupled.
9
9, 10
DGND
Digital Ground.
10
11
CE
Chip Enable. A logic low on this pin powers down the device and puts the charge pump output into three-
state mode. Taking this pin high powers up the device, depending on the status of the Power-Down Bit F2.
11
12
CLK
Serial Clock Input. This serial clock is used to clock in the serial data to the registers. The data is latched into
the 24-bit shift register on the CLK rising edge. This input is a high impedance CMOS input.
12
13
DATA
Serial Data Input. The serial data is loaded MSB first with the two LSBs being the control bits. This input is a
high impedance CMOS input.
13
14
LE
Load Enable, CMOS Input. When LE goes high, the data stored in the shift registers is loaded into one of
the four latches; the latch is selected using the control bits.
14
15
MUXOUT
Multiplexer Output. This allows either the lock detect, the scaled RF, or the scaled reference frequency to
be accessed externally.
15
16, 17
DVDD
Digital Power Supply. This can range from 2.7 V to 3.3 V. Decoupling capacitors to the digital ground plane
should be placed as close as possible to this pin. DVDD must be the same value as AVDD.
16
18
VP
Charge Pump Power Supply. This should be greater than or equal to VDD. In systems where VDD 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 V.
EP
Exposed Pad. The exposed pad must be connected to AGND.
