OSCin
I
Oscillator input. A crystal may be connected between OSCin and OSCout. It is
highly recommended that an external source be ac coupled into this pin (see text).
1
1
OSCout
O
Oscillator output. Pin should be left open if external source is used
2
3
VP
—
Power supply for charge pumps (VP should be greater than or equal to VCC) VP
provides power to the Do, BISW and
φ
P outputs
3
4
VCC
—
Power supply voltage input. Bypass capacitors should be placed as close as
possible to this pin and be connected directly to the ground plane.

Do
O
Internal charge pump output. Do remains on at all times

fIN
I
Prescaler input. The VCO signal is AC–coupled into this pin
8
10
CLK
I
Clock input. Rising edge of the clock shifts data into the shift registers
9
11
DATA
I
Binary serial data input
10
13
LE
I
Load enable input (with internal pull up resistor). When LE is HIGH or OPEN, data
stored in the shift register is transferred into the appropriate latch (depending on
the level of control bit). Also, when LE is HIGH or OPEN, the output of the second
internal charge pump is connected to the BISW pin
11
14
FC
I
Phase control select (with internal pull up resistor). When FC is LOW, the
characteristics of the phase comparator and charge pump are reversed. FC also
selects fp or fr on the fOUT pin
12
15
BISW
O
Analog switch output. When LE is HIGH or OPEN (“analog switch is ON”) the
output of the second charge pump is connected to the BISW pin. When LE is LOW,
BISW is high impedance
13
16
fOUT
O
Phase comparator input signal. When FC is HIGH, fOUT=fr, programmable
reference divider output; when FC is LOW, fOUT=fp, programmable divider output
