TYPE
DESCRIPTION
RSET
19
1
O
The user needs to place an external resistor (RSET) from this pin to ground to control the
maximum charge pump current. This node’s output voltage is typically around 1 V and the
relationship between ICPOUTmax and RSET is:
ICPOUTmax +
23.5
RSET
A 4.7-k resistor placed at this pin to ground would hence provide a maximum charge pump
output current of approximately 5 mA.
CPOUT
20
2
O
Charge pump output. This node provides the charge pump current that ultimately controls the
external VCO.
CPGND
1
3
I
Charge pump ground
AGND
23
4
I
Analog ground
RFIN
4
5
I
Complementary input to the prescaler. For single-ended applications, bypass with a small
capacitor to ground (typically 100 pF).
RFIN
5
6
I
Input to the prescaler. To complete the PLL, this signal must come from the output of the
external VCO.
AVDD
6, 7
7
I
Analog power supply. There are two possible supply ranges: 3 V 3.6 V and 4.5 V 5.5 V.
This value should be the same as the DVDD. Appropriate decoupling is necessary for optimal
performance.
REFIN
8
I
Reference frequency input. This externally provided reference gets divided by the selectable R
divider, and is used to synthesize the desired output frequency. Typically this input is an
ac-coupled sinusoid; however, a TTL or CMOS signal can also be used.
DGND
9, 10
9
I
Digital ground
CE
11
10
I
Chip enable. Setting this pin low puts the device into power down; setting it high activates the
charge pump if the software controlled power down is also disabled.
CLOCK
12
11
I
Serial clock input. This is the input that is used to clock the serial data into the 24-bit shift
register of the device. The data is read at the rising edge of this clock.
DATA
13
12
I
Serial data input. This is the data stream that contains the data to be loaded into the shift
register. The data is loaded MSB first.
LE
14
13
I
Load enable. When this asynchronous signal is asserted high, the data existing in the shift
register get loaded onto the selected latch.
MUXOUT
15
14
O
This user-selectable output can be controlled to provide the digital or analog lock detect
signals, the divide by N RF signal or the divide by R reference. The output can also be
3-stated.
DVDD
16, 17
15
I
Digital power supply. There are two possible supply ranges: 3 V 3.6 V and 4.5 V 5.5 V. This
value should be the same as the AVDD. Appropriate decoupling is necessary for optimal
performance.
VCP
18
16
I
Charge pump supply. This supply must be at least 1 V greater than the AVDD and DVDD and
can be as high as 8 V, accommodating a large range of possible VCOs.
(1) The thermal pad on the bottom of the QFN package may be tied to ground, but is not required to meet specified performance.
