Pin Descriptions
Pin Number
Function
Description
1, 9 - 13, 22, 36
N/C
No Connection. These pins may be connected to RF/DC ground.
Performance will not be affected.
2 - 4, 7, 37, 39
GND [1]
These pins must be connected to RF/DC Ground
5GND
These pins and package bottom
must be connected to RF/DC Ground
8VCCVCO2 [2]
+5V Power Supply for VCO
40
VCCVCO1
6VTUNE
Control Voltage Input. Modulation port bandwidth
dependent on drive source impedance.
14
ACG
AC Ground. This pin must be connected to
an external capacitor to ground.
15
AVCC
Analog Power supply pin for the RF Section.
A decoupling capacitor to the ground plane should
be placed as close as possible to this pin. Nominally 3.3V
16
VDDCP
+5V Power Supply for charge pump digital section
17
VCCCP
+5V Power Supply for the charge pump analog section
18
CP
Charge pump output
19
VDDPFD
Analog Power supply for the phase frequency detector, Nominally 3.3V
20
BIAS [3]
External bypass decoupling for precision bias circuits,
1.920V ±20 mV is generated internally
21
AVDD
Analog Power supply for analog ref paths, Nominally 3.3V
23
REFN
Reference input (Negative or AC coupled to GND)
24
REFP
Reference input (Positive)
25
RVDD
Ref path supply
26
DVDDQ
Digital supply for Substrate, Nominally 3.3V
27
CE
Chip Enable
28
SEN
Serial port latch enable input
29
SCK
Serial port clock input
30
SDI
Serial port data input
31
DVDD
Power supply pin for internal digital circuitry. Nominally 3.3V
32
VDDIO
Power Supply for digital I/O driver
33
LD_SDO
Lock Detect, Main Serial Data Output
or VCO Serial Port Data Out
34
VCCPS
Analog Power Supply for Prescaler, Nominally 3.3V
35
DVDDM
Digital Power Supply for M-Counter, Nominally 3.3V
38
RFOUT
RF output (AC coupled).
[1] This pin is not connected internally, however, this pin must be connected to GND to maintain product family pin for pin compatibility.
[2] This pin is not connected internally, however, this pin must be connected to Vcc to maintain product family pin for pin compatibility.
[3] BIAS ref voltage (pin 20) cannot drive an external load, and must be measured with a 10 GOhm meter such as Agilent 34410A; a typical
10 Mohm DVM will read erroneously.
