Product Specification

Figure 11. Application Example

Note 1:

For optimum fractional spur and lock-time performance C2 and C5 should be polyester (or poly

propylene). In addition, the loop filter components must be free from contamination. Contamination

will result in poor spur performance. For accurate loop bandwidth, C1 must be greater than or equal to

100 pF, and C4 must be greater than or equal to 200 pF.
