Fig. 11 Typical applications circuit

* Insert C15, delete R4 and R5 if CON2 is to be used to monitor the VCO. Delete C15 insert R4 and R5 if CON is to provide

an external source, otherwise short C15 and delete R4, R5 and CON2.

NOTES

1. With the exception of electrolytics, all capacitors are surface mount types.

2. All resistors are 0.25W, ±2%.

3. C0, C1, C2, C11, C12, C13 and C14 must be low leakage types.

4. R18 may be required to optimise VCO close in noise performance.
