If frequency fV is greater than fR or if the phase of fV is
leading, then error information is provided by
φ
V pulsing low.
φ
R remains essentially high.
If the frequency fV is less than fR or if the phase of fV is
lagging, then error information is provided by
φ
R pulsing low.
φ
V remains essentially high.
If the frequency of fV = fR and both are in phase, then both
φ
V and
φ
R remain high except for a small minimum time
period when both pulse low in phase.
fR, fV
R Counter Output, N Counter Output (Pins 13, 3)
Buffered, divided reference and fin frequency outputs. The
fR and fV outputs are connected internally to the
÷
R and
÷
N
counter outputs respectively, allowing the counters to be
used independently, as well as monitoring the phase detector
inputs.
LD
Lock Detector Output (Pin 7)
This output is essentially at a high level when the loop is
locked (fR, fV of same phase and frequency), and pulses low
when loop is out of lock.
REFout
Buffered Reference Oscillator Output (Pin 14)
This output can be used as a second local oscillator, refer-
ence oscillator to another frequency synthesizer, or as the
system clock to a microprocessor controller.
S/Rout
Shift Register Output (Pin 12)
This output can be connected to an external shift register
to provide band switching, control information, and counter
programming code checking.
POWER SUPPLY
VDD
Positive Power Supply (Pin 4)
The positive power supply potential. This pin may range
from +3 to +9 V with respect to VSS.
VSS
Negative Power Supply (Pin 6)
The most negative supply potential. This pin is usually
ground.
