摘要：
A digital-to-phase or digital-to-time-shift converter (100) includes a delay line (106), a multiplexor (108) and synchronization circuit (110). In the converter (100) the clock edges of a reference signal are shifted in response to the value of a multi-bit digital word, IN (104). The synchronization circuit (110) gates the output of the multiplexor (108) such that a pulse appears at the synchronization circuit's (110) output port (114) only when the circuit is gated by a signal at input TRIG (112). The synchronization circuit (110) creates a time aperture for the multiplexor output.
