    • A method for synchronizing a plurality of programmable timing verniers with a reference pulse signal, each of the verniers being programmable to one of a plurality of timing steps within a delay range determined by a control signal applied to a bias input. A first and second control vernier is selected from the plurality of verniers, the first control vernier is programmed to a first delay, and the second control vernier is programmed to a second delay. The first and second control verniers are triggered together to generate respective first and second delay signals.
