Description
Power supply voltage input for RF1 analog and RF1 digital circuits. Input may range
from 2.7V to 5.5V. V
CC
1 must equal V
CC
2. Bypass capacitors should be placed as
close as possible to this pin and be connected directly to the ground plane.
Power supply for RF1 charge pump. Must be
≥
V
CC
.
RF1 charge pump output. For connection to a loop filter for driving the input of an
external VCO.
LMX2335/37: Ground for RF1 analog and RF1 digital circuits. LMX2336: Ground for RF
digital circuitry.
First RF prescaler input. Small signal input from the VCO.
RF1 prescaler complementary input. A bypass capacitor should be placed as close as
possible to this pin and be connected directly to the ground plane. Capacitor is optional
with loss of some sensitivity.
Ground for RF1 analog circuitry.
Oscillator input. The input has a V
CC
/2 input threshold and can be driven from an
external CMOS or TTL logic gate.
Oscillator output.
Multiplexed output of the programmable or reference dividers, lock detect signals and
Fastlock mode. CMOS output (see Programmable Modes)
High impedance CMOS Clock input. Data for the various latches is clocked in on the
rising edge, into the 20-bit shift register.
Binary serial data input. Data entered MSB first. The last two bits are the control bits.
High impedance CMOS input.
Load enable high impedance CMOS input. When LE goes HIGH, data stored in the
shift registers is loaded into one of the 4 appropriate latches (control bit dependent).
Ground for RF2 analog circuitry.
RF2 prescaler complementary input. A bypass capacitor should be placed as close as
possible to this pin and be connected directly to the ground plane. Capacitor is optional
with loss of some sensitivity.
RF2 prescaler input. Small signal input from the VCO.
LMX2335/37: Ground for RF2 analog, RF2 digital, MICROWIRE

LD and Oscillator
circuits. LMX2336: Ground for RF2 digital, MICROWIRE, F
o
LD and Oscillator circuits.
RF2 charge pump output. For connection to a loop filter for driving the input of an
external VCO.
