Non-whole-number frequency divider for e.g. PC motherboard synthesizes generated edge triggered clock signals whose rising edge or falling edge is synchronized with rising edge or falling edge of original clock frequency

摘要

A phase shifter changes original clock frequency into preset number of phase shifted versions of the original clock frequency. Generators are input with the original clock frequency and phase shifted versions to synchronize rising edge or falling edge of edge triggered clock signals with rising edge or falling edge of the original clock frequency. A synthesizer (30) synthesizes the generated edge triggered clock signals.
