Abstract

um circuito de geração do relógio é operativo para desabilitar e habilitar uma pluralidade de sinais de relógio de saída mantendo ainda relacionamentos de fase predeterminados entre os sinais de relógio. um sinal de relógio de referência é dividido por um fator de pelo menos dois, para gerar um sinal de relógio mestre. uma pluralidade de circuitos de fase, cada qual independentemente habilitado, gera uma pluralidade de sinais de relógio de saída dividindo o sinal de relógio de referência. os sinais de relógio de saída têm relacionamentos de fase predeterminado relativos um com o outro. cada circuito de fase é habilitado sincronizadamente para uma borda de sincronização do sinal de relógio mestre. um circuito de sincronização associado com cada circuito de fase assegura sincronização com o sinal de relógio mestre produzindo um sinal de habilitação do circuito de fase somente nas condições em que um sinal de habilitação de relógio associado com o relógio de saída é afirmado e um número predeterminado de bordas de sincronização de sinal de relógio mestre é recebido.
