Abstract
A multiphase clock generating apparatus includes a clock generator providing an M-clock having a frequency M times that of a received reference clock. Divider circuitry is coupled to provide an alignment signal having 1/M the frequency of the M-clock. A recovery circuit recovers up to M distinct clocks from the M-clock in accordance with the alignment signal. The recovered clocks have substantially an N•180°/M phase difference from each other, wherein N≧1.
