Abstract:
A precision timing generator, comprising:a coarse timing generator that receives a clock signal and a timing command input and generates a coarse timing signal;a fine timing generator including a sine generator and a phase shifter, wherein the sine generator receives the clock signal and generates a sine wave signal (Sin 2 .pi.ft), and wherein the phase shifter receives the sine wave signal (Sin 2 .pi.ft) and the timing command input and phase shifts the sine wave signal (Sin 2 .pi.ft) based on a fine timing component of the timing command input to generate a phase shifted sine wave signal (Sin 2 .pi.ft+B) having a desired phase shift (B);a converter that converts the phase shifted sine wave signal into a square wave signal having the desired phase shift (B), wherein the square wave signal comprises a fine timing signal; anda combiner that uses the fine timing signal and the coarse timing signal to generate precision timing signal.
