Method and apparatus for calibrating a delay locked loop charge pump current |
摘要 |
A calibration and adjustment system for post-fabrication control of a delay locked loop charge pump current is provided. The calibration and adjustment system includes an adjustment device that varies an amount of charge pump current. Such control of the charge pump current in a delay locked loop allows a designer to achieve a desired delay locked loop operating characteristic after the delay locked loop has been fabricated. A representative value of the amount of adjustment desired in the charge pump current may be stored and subsequently read to adjust the delay locked loop.
