... Pin 12, needs to be grounded and Pin 13 has a 3.9k resistor to ground. Timing cap, C and for 70MHz operation with temperature compensation network should be 16pF, not 34pF as was used in the NE568. The NE568A has the following improvements: ESD protected; extended V range from 4.5V to 5.5V; operating temperature range -55 to 125 C (see Signetics Military 568A data sheet) ...

... JA ELECTRICAL CHARACTERISTICS The elctrical characteristics listed below are actual tests (unless otherwise stated) performed on each device with an automatic IC tester prior to shipment. Performance of the device in automated test set-up is not necessarily optimum. The NE568A is DC ELECTRICAL CHARACTERISTICS 70MHz, Test Circuit Figure 3, f ...

... The loop filter determines the dynamic characteristics of the loop. In most PLLs, the phase detector outputs are internally connected to the ICO inputs. The NE568A was designed with filter output to input connections from Pins 20 ( DET (ICO), and Pins 19 ( DET (ICO) external. This allows the use of both series and shunt loop-filter elements ...
