Generating digital square-wave signals at logic levels from fast signals having frequencies up to 150 MHz (such as sinusoidal signals from quartz-crystal oscillators) is not particularly easy. The discrete circuits used for this purpose are relatively complex and require fast HF transistors.This problem can now be solved in a considerably simpler manner using the fast Linear Technology LT1715 dual comparator (www.linear-tech.com/pdf/1715f.pdf).
