System and method for accurate adjustment of discrete integrated circuit delay lines

The present invention is related to delay lines, and more particularly to a system and method for controlling the amount of delay over a range of delays and operating conditions. A system and method of controlling delay in a delay line. In a delay line having a system mode and an oscillator mode, wherein the delay line delays a signal as a function of a delay code, the method comprises setting the delay code, placing the delay line in oscillator mode, determining frequency of oscillation of the delay line, comparing the frequency of oscillation to a target frequency and adjusting the delay code until the frequency of oscillation of the delay line is substantially equal to the target frequency.
