Abstract
A device for passive equalization and slew-rate control of a signal includes a first branch that includes a first driver coupled in series with an equalization capacitor, and a second branch that includes a second driver coupled in series with a resistor. The second branch may be coupled in parallel to the first branch, and the first branch may be configurable to enable one of passive equalization or slew-rate control of the signal based on a mode control signal.

A device for passive equalization and slew-rate control of a signal, the device comprising:
- a first branch comprising a first driver coupled in series with an equalization capacitor;
- and
- a second branch comprising a second driver coupled in series with a resistor,
- wherein the second branch is coupled in parallel to the first branch, and the first branch is configurable to enable one of passive equalization or slew-rate control of the signal based on a mode control signal.
A method for providing a device for enabling passive equalization and slew rate control of a signal, the method comprising:
- coupling a first driver in series with an equalization capacitor to form a first branch;
- coupling a second driver in series with a resistor to form a second branch;
- coupling the second branch in parallel to the first branch;
- and
- configuring the first branch to enable one of passive equalization or slew-rate control of the signal based on a mode control signal.
A system comprising:
- a transmit circuit configured to transmit a signal;
- and
- a device for passive equalization and slew-rate control of the signal, the device comprising:
- a first branch that includes a first driver coupled in series with an equalization capacitor;
- and
- a second branch that includes a second driver coupled in series with a resistor,
- wherein the second branch is coupled in parallel to the first branch and the first branch is configurable to enable one of passive equalization or slew-rate control based on a mode control signal.
