A circuit for latching inputs and enabling outputs on a bidirectional pin using a PLL lock detect circuit is disclosed. A PLL lock detect circuit generates an active lock control signal when an output reference signal is phase locked relative to an input reference signal applied to a phase locked...http://www.google.fr/patents/US5764714?utm_source=gb-gplus-shareBrevet US5764714 - Latching inputs and enabling outputs on bidirectional pins with a phase locked loop (PLL) lock detect circuit
