Divide by three clock divider with symmertical output

A divide by three digital clock divider circuit providing a symmetrical output, comprising:

• a divide by one and one-half circuit comprising flip-flop means and gate means for receiving clock pulses of frequency F and generating a plurality of nonaligned staggered signal streams with nonsymmetrical pulses of frequency 1/3F including first and second 1/3F streams each having a duty cycle of substantially 33%, said gate means gating said clock pulses against said first 1/3F stream to yield output pulses during the first half of the duty portion of a cycle of said first 1/3F stream, and gating said clock pulses against said second 1/3F stream to yield output pulses during the second half of the duty portion of a cycle of said second 1/3F stream, such that the output of said divide by one and one-half circuit provides pulses of frequency 2/3F with a duty cycle of substantially 33%;
• and
• a divide by two flip-flop clocked by said divide by one and one-half circuit to provide symmetrical 1/3F output pulses.
