Pin Description
VCC1
1
24
19
P
Power Supply Connection for PLL1 and PLL2: When power
is removed from both the VCC1 and VCC2 pins, all latched data
is lost.
VP12
2
20
P
PLL1 Charge Pump Rail Voltage: This voltage accommo-
dates VCO circuits with tuning voltages higher than the VCC of
PLL1.
DOPLL1
3
1
O
PLL1 Charge Pump Output: The phase detector gain is IP/2π.
Sense polarity can be reversed by setting the FC bit in software
(via the Shift Register).
FIN1
553
I
Input to PLL1 Prescaler: Maximum frequency 1.2 GHz.
FIN1#
664
I
Complementary Input to PLL1 Prescaler: A bypass capacitor
should be placed as close as possible to this pin and must be
connected directly to the ground plane.
OSC_IN
886
I
Oscillator Input: This input has a VCC/2 threshold and CMOS
logic level sensitivity.
FO/LD
10
11
8
O
Lock Detect Pin of PLL1 Section: This output is HIGH when
the loop is locked. It is multiplexed to the output of the program-
mable counters or reference dividers in the test program mode.
(Refer to Table 3 for configuration.)
CLOCK
11

9
I
Data Clock Input: One bit of data is loaded into the Shift Reg-
ister on the rising edge of this signal.
DATA

I
Serial Data Input
LE
13
15
11
I
Load Enable: On the rising edge of this signal, the data stored
in the Shift Register is latched into the reference counter and
configuration controls, PLL1 or PLL2 depending on the state of
the control bits.
FIN2#
15
17
13
I
Complementary Input to PLL2 Prescaler: A bypass capacitor
should be placed as close as possible to this pin and must be
connected directly to the ground plane.
FIN2
161814
I
Input to PLL2 Prescaler: Maximum frequency 600 MHz.
DOPLL2

O
PLL2 Charge Pump Output: The phase detector gain is IP/2π.
Sense polarity can be reversed by setting the FC bit in software
(via the Shift Register).
VP2

P
PLL2 Charge Pump Rail Voltage: This voltage accommo-
dates VCO circuits with tuning voltages higher than the VCC of
PLL2.
VCC2
202318
P
Power Supply Connections for PLL1 and PLL2: When power
is removed from both the VCC1 and VCC2 pins, all latched data
is lost.
