NOTES:
1. When used, the
φ
R and
φ
V outputs are fed to an external combiner/loop filter. See the Phase–Locked
Loop — Low–Pass Filter Design page for additional information.
2. Transistor Q1 is required only if the standby feature is needed. Q1 permits the bipolar section of the device to
be shut down via use of the general–purpose digital pin, OUTPUT B. If the standby feature is not needed, tie
Pin 12 directly to the power supply.
3. For optimum performance, bypass the VCC, VDD, and VPD pins to GND with low–inductance capacitors.
4. The R counter is programmed for a divide value = REFin/fR. Typically, fR is the tuning resolution required for
the VCO. Also, the VCO frequency divided by fR = NT = N
×
64 + A; this determines the values (N, A) that must
be programmed into the N and A counters, respectively.
