FoLD
O
Multiplexed output of the Main/Aux programmable or reference dividers
and Main/Aux lock detect. CMOS output. (See Programming Description
2.5)
1

OSC
IN
I
PLL reference input which drives both the Main and Aux R counter
inputs. Has about 1.2V input threshold and can be driven from an
external CMOS or TTL logic gate. Typically connected to a TCXO output.
Can be used with an external resonator (See Programming Description
2.5.4).

AUX
I
Aux prescaler input. Small signal input from the VCO.
56
V
CCAUX
—
Aux PLL power supply voltage input. Must be equal to V
CCMAIN. May
range from 2.7V to 3.6V. Bypass capacitors should be placed as close
as possible to this pin and be connected directly to the ground plane.

CPo
AUX
O
Aux PLL Charge Pump output. Connected to a loop filter for driving the
control input of an external VCO.
78
EN
AUX
I
Powers down the Aux PLL when LOW (N and R counters, prescaler, and
tristates charge pump output). Bringing EN
AUX HIGH powers up the Aux
PLL.
89
EN
MAIN
I
Powers down the Main PLL when LOW (N and R counters, prescaler,
and tristates charge pump output). Bringing EN
MAIN HIGH powers up the
Main PLL.

GND
—
Main PLL ground.

LE
I
Load enable high impedance CMOS input. Data stored in the shift
registers is loaded into one of the 4 internal latches when LE goes HIGH
(control bit dependent).
14
15
Data
I
High impedance CMOS input. Binary serial data input. Data entered MSB
first. The last two bits are the control bits.
15
16
Clock
I
High impedance CMOS Clock input. Data for the various counters is
clocked in on the rising edge, into the 18-bit shift register.
