Abstract:
A circuit for transferring a n-bit phase value between circuits includes a system clock input, a n-bit phase value generator coupled to the system clock input generating a phase value output, and an edge output indicating the phase output value is valid, a latching clock delay circuit having an input coupled to the system clock input, an input coupled to the edge output, a variable phase delay circuit coupled to the phase value output, a delay adder having a first input coupled to the phase value output, a second input coupled to a delay offset signal, and an output coupled to the control input of the variable phase delay circuit, and a phase flip-flop having a data input coupled to the output of the variable phase delay circuit, a clock input coupled to a latching clock output of the variable output clock delay circuit and a Phase Out output.
