Biphase vernier time code generator

A time code generator for generating a digital value associated with the arrival time of an event, such as a logical transition of a digital signal. In one embodiment, the time code generator includes a pair of oscillators configured to generate a plurality of oscillating signals of differing phases relative to the system clock. A first and second phase counters are each driven by one of the plurality of oscillating signals. Each of the oscillating signals drives a separate vernier interpolator configured to capture an event. A composite time coder is in communication with the phase counters and the plurality of vernier interpolators to generate a digital value indicating the arrival time of the event.
