Description

I
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.
LMX2335L: Ground for RF2 analog, RF2 digital, MICROWIRE,
F

LD and Oscillator circuits. LMX2336L: Ground for IF 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.
Power supply for RF2 charge pump. Must be

LD and oscillator circuits. Input may range from
2.7V to 5.5V. V

CC
1. Bypass capacitors should
be placed as close as possible to this pin and be connected
directly to the ground plane.
