9.3.3 Loop Filter

The phase locked loop (PLL) included in the LM567 has a pin for connecting the low pass loop filter capacitor. The selection of the capacitor for the filter depends on the desired bandwidth. The device bandwidth selection is different according to the input voltage level. Refer to the Section 9.4.1 section and the Section 9.4.2 section for more information about the loop filter capacitor selection.
