Title: Digital voltage controlled oscillator
Inventor: SUEHIRO YOSHIKAZU
IPC: H03L7/06
Filed: 1984-12-29
Abstract: PURPOSE:To obtain a digital voltage controlled oscillator having double clocks of highest output by executing the division at the rise and fall points of the pulse output of a fixed oscillator and then executing the division by R/2 in each of said two cases. CONSTITUTION:In case a delay detecting signal 9 is set at an H level where a delay is detected, a counter 8 is set under a rise operation state before the signal 9 is set at an H level. In other words, the output Q21 of a positive edge D-FF6 is set at an H level. While the advance or delay of the phase is decided at the rise point of a clock 12. When the signal 9 is set at an H level, the output Q21 is changed to an L level. Thus a reversed signal of 8phi0 is supplied to the counter 8. That is, a counting action carried out so far at the rise point of 8phi0 is done at a fall point. Thus the output Q235 of the counter 8 is reduced by half cycle compared with 8phi011.
