Description
LE
I
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 IF analog circuitry.
IF 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 some loss of sensitivity.
IF prescaler input. Small signal input from the VCO.
Ground for IF digital, MICROWIRE, F
o
LD, and oscillator circuits.
IF charge pump output. For connection to a loop filter for driving the
input of an external VCO.
Power Supply for IF charge pump. Must be
