摘要： A programmable circuit for generating a clock signal is disclosed. The present invention provides a clock generator architecture that combines PLL-based clock generator circuitry with an on-chip EPROM in a monolithic clock generator chip. The clock generator allows for electrical configuration of various information including PLL parameters, input thresholds, output drive levels and output frequencies. The various parameters can be configured after the clock generator is fabricated. The parameters can be configured either during wafer sort or after packaging. The clock generator can be erased prior to packaging so programming can be verified.

摘要： 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 loop (PLL) circuit. A latch and enable circuit is responsive to this lock control signal to latch the input signal (off of the pin), and, thereafter, enable output of an output signal onto the bidirectional pin. The latch and enable circuit includes a data latch to store the input signal when the lock control signal goes to an active state. The latch and enable circuit also includes a delay circuit to delay the lock control signal to produce a delayed lock control signal, and a tristateable output driver that is tristated when the delayed lock control signal is inactive, but, operates to pass (i.e., enable) the output signal to the bidirectional pin when the delayed lock control signal is active.
