Abstract
A simple, reliable, divide by 1.5 clock generator is provided. This is done by using a divide by 3 circuit with three gates. The first two gates are clocked by the RLL clock, and the third gate is clocked by the inverse of the RLL clock. The output of the first gate is combined with the RLL clock to provide an output pulse. Another output is produced when the output of the third gate is combined with the inverse of the RLL clock. The combination of these two outputs thus produces a divide by 1.5 clock with a precisely placed rising edge. The output clock is not symmetrical, but the rising edge (or the falling edge on its inverse) is precisely placed at the 1.5 frequency.
