Abstract
A signal conditioner can include a state machine configured to detect a predetermined protocol level mode of a data signal on a bi-directional serial bus. The signal conditioner can also include a re-driver configured to inject current into at least one of a rising edge and a falling edge of the data signal on the bi-directional serial bus in response to the detection of the predetermined protocol level mode.
Claims20
A signal conditioner comprising:
- a state machine configured to detect a predetermined protocol level mode of a data signal on a bi-directional serial bus;
- and
- a re-driver configured to inject current into at least one of a rising edge and a falling edge of the data signal on the bi-directional serial bus in response to the detection of the predetermined protocol level mode.
A system comprising:
- a given universal serial bus (USB) device that communicates with another USB device via a USB channel;
- and
- a signal conditioner comprising:
- a state machine configured to detect a predetermined protocol level mode of a data signal propagated on the USB channel;
- and
- a re-driver configured to inject current into at least one of a rising edge and a falling edge of the data signal on the USB channel in response to the detection of the predetermined protocol level mode.
3 more elements
A method comprising:
- detecting, at a state machine, a predetermined protocol level mode of a data signal propagated across a universal serial bus (USB);
- injecting, by a re-driver, a positive current into the data signal in response to detecting a rising edge of the data signal that has a rise time greater than a predetermined maximum rise time;
- and
- injecting, by the re-driver, a negative current into the data signal in response to detecting a falling edge of the data signal that has a fall time greater than a predetermined maximum fall time.
