# High frequency clock from clocked RS latch

We were taught that this circuit is not of much use as when CLK=1, J=1 & K=1, Q toggles at a very high rate. So suppose I want to make a high-frequency clock, can I use this?
Of course, the frequency itself can't be changed for given logic gates, but can I make a clock from this by giving high inputs at CLK,J and K? (I don't care about the exact frequency, it should just be like in MHz)

• Possibly, but there are more reliable ways to make oscillators, why go for this way? – user253751 Apr 26 '18 at 3:07
