Rise and Fall Time Mismatch Adjustment Circuit for USB-On-The-Go Modules

Abstract:

An apparatus may include an output pin, an output driver circuit communicatively coupled to the output pin and configured to output a rising signal or falling signal on the output pin, and a programmable current source communicatively coupled to the output driver circuit. The programmable current source may be configured to drive a speed of a rising signal or of a falling signal on the output pin and, based upon adjustment data, increase or decrease current to the output driver circuit to change the speed of the rising signal or of the falling signal on the output pin.
