Asjad,
There are two outputs on this circuit! The top half uses two D-type flip flops. The second one (FF2) is the one that contains the outputs. On the right of it are two connectors, Q and NOT Q, (Q with a bar above it). The one that you need to connect to your PIC is the Q output.
All the NOT Q output does, is give you an inverse of the Q output. So, say there was +5v on Q, there would be -5v on NOT Q.
As for the bottom half of the circuit. That is just an oscillator circuit. Which provides FF2 with a clock pulse.
I would use this circuit, if it was on the datasheet then it will have all the right characteristics and ratings for your PIC in that particular circuit. So good luck!
