The 2nd LO. External tank components are
required. The internal capacitance across the pins
is adjustable from 0 to 7.6 pF for fine tuning
performance with bits 7/20–18.
LO2 Control is the dc control input for this VCO.
Typically it is the output of the low–pass filter fed
from the phase detector output.
Ground pin for the LO2 section. A direct connection
to a ground plane is strongly recommended.
LO2 Phase Detector Output. The output either
sources or sinks current, or neither, depending on
the phase difference of the phase detector input
signals. During lock, very narrow pulses with a
frequency equal to the PLL reference frequency are
present. Output current is either 100 µA or
Ground pin for the LO2 section. A direct connection
to a ground plane is strongly recommended.
400 µA, selectable with bit 3/14.
