Abstract
A closed loop delay line system () includes a phase lock loop that provides a phase lock output signal (). A delay line () includes a clock input, a delay line output, and a delay line bias input. A bias signal provided to the delay line bias input () adjusts the speed of the delay line (). A phase detector () compares phase between a first timing signal input () and the delay line output (). A bias adjust circuit () mixes the phase compare output signal () and the phase lock output signal () to provide a combination bias signal () to the delay line (). Additionally, the relative timing position of strobe outputs () from the delay line () can be individually adjusted.
