Pin Description
Power Supply Connection for PLL1 and PLL2:
When power
is removed from both the V
CC
1 and V
CC
2 pins, all latched data
is lost.
PLL1 Charge Pump Rail Voltage:
This voltage accommo-
dates VCO circuits with tuning voltages higher than the V
CC
of
PLL1.
PLL1 Charge Pump Output:
The phase detector gain is I
P
/2
π
.
Sense polarity can be reversed by setting the FC bit in software
(via the Shift Register).
Input to PLL1 Prescaler:
Maximum frequency 2.5 GHz.
Complementary Input to PLL1 Prescaler:
A bypass capaci-
tor should be placed as close as possible to this pin and must
be connected directly to the ground plane.
Oscillator Input:
This input has a V
CC
/2 threshold and CMOS
logic level sensitivity.
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.)
Data Clock Input:
One bit of data is loaded into the Shift Reg-
ister on the rising edge of this signal.
Serial Data Input
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.
Complementary Input to PLL2 Prescaler:
A bypass capaci-
tor should be placed as close as possible to this pin and must
be connected directly to the ground plane.
Input to PLL2 Prescaler:
Maximum frequency 600 MHz.
PLL2 Charge Pump Output:
The phase detector gain is I
P
/2
π
.
Sense polarity can be reversed by setting the FC bit in software
(via the Shift Register).
PLL2 Charge Pump Rail Voltage:
This voltage accommo-
dates VCO circuits with tuning voltages higher than the V
CC
of
PLL2.
Power Supply Connections for PLL1 and PLL2:
When pow-
er is removed from both the V
CC
1 and V
CC
2 pins, all latched
data is lost.
Analog and Digital Ground Connections:
This pin must be
grounded.
