What is the best way to convert a square wave to a sine wave? I was thinking of putting it through a LPF. Basicly, I need to convert the square wave output of a PLL to a sine. Mind you, the square wave frequency is not fixed, it will be changing.

Linearity can be expressed by the amplitude of fundamental freq. component (freq. you want) relative to adjacent second harmonic freq. component.
Linearity is the best if your oscillator has only single fundamental component..
You can make a simple sinusoidal oscillator using a 555 oscillator and simple LPF..
Depending on frequency.. This

How often do you want your 5 cycles? Do you want the cycles to be switched on at a certain part of the waveform. It looks like pin 3 controls the output level, so link it to V cc with a high value resistor. Then a 555 timer chip can be used as a monostable, if you set its time to (250KHz = 4 microS period X 5) to 20 microseconds to the output of t

You can use a comparator and connect a variable DC voltage to one of the inputs to vary the trigger point on the sine wave.
Use the comparator output to trigger a one-shot such as with a 555 or a CD4098 to get a fixed pulse-width output.
