Beschreibung
Zusammenfassung:	A driver, includes a driver block, a controller block, and a comparison block. The driver block includes an adjustable current source configured to produce a digital output stream. The controller block is coupled to the driver block. The comparison block is coupled to the driver block and the controller block. The comparison block is configured to compare the digital output stream to a reference value at a time delayed with respect to a master clock and based upon the comparison cause the controller block to adjust a strength of the driver block.
